Landscape Design Solutions

Posted on by

Gardens illicit emotions, tell a story, and provide an escape from the mundane. They must also be sustainable, functional, and change with the seasons. Landscape design inspired by the union of form and function, results in uniquely beautiful gardens that meet a set of design criteria. From this perspective, most challenges are simply opportunities for creative problem-solving.

Below are some garden challenges and strategies for solving them.

A low-maintenance garden.

How do you define low maintenance? How much work are you willing to do or hire out? Realistic expectations help a designer create a garden that fits your lifestyle. A well-defined maintenance plan takes the guess work out of garden care. Proactive maintenance saves time, money and keeps your garden healthy and looking good. Deferred maintenance can lead to unhealthy, unattractive plants.

A water-wise garden

Understand how much supplemental water your desired garden will require. The effectiveness of watering can be maximized by grouping complementary plants in zones according to their water requirements. Place plants that need the most water close by, and those that need the least, in outer zones. Plants at the outside edge may not need any supplemental water once established. This method requires careful plant selection and a watering plan or a drip system with multiple zones.

A colorful garden

Color is derived from both foliage and flowers. In the Maritime Pacific Northwest, evergreen plants provide interest during wintertime. Some evergreens may also have colorful needles, foliage, and seasonal flowers. However, perennials provide the greatest spectrum of concentrated color for the longest period. A well-designed plan including perennials and evergreen plants will provide flowers throughout the seasons.

A shade garden

Dappled shade provides an opportunity to create a lush tapestry of color, texture, and flowers. There are also plenty of plants that thrive in full shade. Some of the same plants are equally at home when planted en masse or grouped in elegant drifts. Many of these plants are perennials, but handsome broad-leaf evergreens and conifers will provide structure in a shade garden, especially during wintertime.

As each site and every client is different, so is every garden one of a kind.

Power Perennials

Posted on by

It’s peak season for summer-blooming perennials – the easiest way to enjoy reliable flowers all summer without having to replant annuals. If you’re considering adding perennials to your garden or expanding the collection you already have, now is the time.

My list of power perennials are plants with an abundance of flowers and a long bloom cycle. They are also water-wise, adaptable, and low-maintenance.

Here are some of my favorites:

Achellia (Yarrow). This tried and true perennial has several exotic cultivars that are just as versatile and tough as the old-fashioned, and still popular, bright yellow ‘Moonshine’. The flowers of Achellia millefolium ‘Sassy Summer Sangria’ are a multitude of individual deep coral-red florets with a white eye and ‘Sassy Summer Sunset’ has red-orange florets with a yellow eye. Woody stems hold the flower heads above a clump of soft, feathery green-gray foliage. Achellia does best in well-drained average soil with some supplemental water, but once established it will tolerate short periods of drought.

Salvia (Sage). A large genus that includes several species and numerous cultivars. Here, I am focus on Salvia nemorosa. ‘Marcus’, one of the most compact cultivars, has deep purple flower spikes above a low basal clump of silvery-green foliage. Its diminutive size and uniform appearance make it a good choice for a seasonal border or edging a perennial garden. ‘Rose Marvel’ has small leaves along upright stems with flower spikes lined composed of rose-colored florets. Its unique color and form add continuity when repeated in combination with other plants. Salvia will bloom throughout summer if the spent flower heads are removed. It thrives in full sun and may become leggy with too much moisture or not enough sun.

Nepeta (Catnip). Hybrid Nepeta x faassenii has low, spreading stems of soft gray-green foliage that extend outward horizontally giving the plant a graceful, symmetrical appearance. Each stem develops a flower spike at the end making the plant a solid mass color when in bloom. ‘Walker’s Low’ has light blue flowers and may reach more than 24″ across in a single season making it an excellent seasonal ground cover or colorful mass planting. ‘Cat’s Pajamas’ is a compact cultivar with indigo blue flowers and rosy-purple calyxes that remain after the flowers are spent. Catnip x faassenii hybrids have a long growth season – foliage emerges in early spring and plants continue to bloom until frost. If plants become leggy mid-season, cut them back to encourage a new flush of foliage and flowers.

This summer is a great time to add perennials to your garden while there is still a good selection in nurseries. If you are not ready to plant, make notes and take pictures of your favorites and I can help you identify them.

If you’re ready to start fresh, renovate or just need a change, now is the time to evaluate your garden and complete design plans to execute this fall.

A Haven For Hummingbirds

Posted on by

Hummingbirds are one of the most popular and esteemed visitors to any garden. Why are we so fascinated by them? Is it the familiar humming sound they make as they hover with the precision of a drone? Or is it the way they dart from flower to flower with energy and determination?

Aster

If you want to attract hummingbirds to your garden, plant what they love. These intriguing little birds will appear like magic if you give them the goods. The same flowers you plant to attract hummingbirds will attract other friendly pollinators that want to join in the flower power.

Not all hummingbirds migrate south during the winter. Those that do, put on weight before their long migration, expending more than half their body weight in reaching their destinations. Those that don’t leave, seek late-blooming perennials such as salvia that bloom until frost. During wintertime they search for any nectar-rich flowers that might still be blooming and will also frequent well stocked humming bird feeders.

Here are some hardy summer and autumn blooming perennials that you can plant now. They will keep hummingbirds around and also refresh your garden when other perennials are declining at the end of summer.

Asters

Asters bloom profusely from late summer until frost. Their dense habit, bright green foliage, and delicate flowers give a tired perennial border a fresh look just when it needs it the most. This is a great choice for mass plantings.

Nepeta (catnip)

Nepeta blooms from late spring until frost making it one of the longest-blooming perennials in this region. Cutting it back mid-season will keep plants tidy and force a new flush of foliage and flowers. There are several varieties to choose from.

Salvia guaranitica ‘Black and Blue’ (Black And Bloom Salvia)

This variety of salvia is a favorite among hummingbirds and its grass-green foliage and deep blue flowers are a dramatic addition to a perennial border. Racemes holding delicate black buds emerge at the end of waist-high woody stems making them easy for hummingbirds to access and giving onlookers an excellent vantage point.

Agastache (Hummingbird Mint)

The name pretty much says it all. Most varieties bloom throughout summer and into fall. Their tidy upright habit makes them a good vertical feature in a perennial border. They are easy to grow and a multitude of tiny flowers on spire-like racemes have a luscious scent.

Hard Working Perennials For Lazy Gardeners

Posted on by

Do you crave a profusion of flowers in the spring and summer? An investment in blooming perennials will bring those glorious blossoms to your garden. Depending on the variety, perennials bloom from spring through autumn and come back bigger and better each year, needing only occasional dividing. If you want to attract bees, butterflies and hummingbirds to your garden, planting perennials is one of the best ways to do it.

Here are three of my favorite perennials that thrive in a sunny location without a lot of water or special care. All you need to do to keep these plants tidy and encourage flower production is remove spent flowers during the growing season.

Penstemon (Beardtongue)

Penstemon x ‘Pretty Petticoat’

Penstemon come in a variety of shapes, colors, and bloom times—so you’re sure to find one that work for your garden. Penstemon does best in a sunny location, tolerates imperfect soil, and is drought tolerant once it’s established. Some varieties bloom with multiple spires of flowers held upright on woody stems, while others have sweeping sprays of flowers on low, bushy plants. Plant Beardtongue in masses of a single color or mixed colors or repeat them throughout a perennial border for continuity. You can also use them to add color among broadleaf evergreens or spring-blooming plants that have finished blooming for the season. For example, low and bushy Penstemon heterophyllus ‘Electric Blue’ is covered with a multitude of iridescent blue flowers all summer. By contrast, tidy-looking Penstemon digitalis ‘Pretty Petticoats’ has upright stems with sturdy stalks of flowers that keep coming until frost.

Salvia

Salvia is another large genus of flowering perennials and plants. Some varieties have masses of flowers on rounded, twiggy plants, while others are herbaceous with upright flower stalks originating from a basal clump. Salvia requires sun but it’s not too picky about soil and can thrive without a lot of water. Herbaceous varieties can be cut back mid-season if the flowering stems become leggy or fall over under the weight of rain. This is truly one of the easiest plants to grow. Salvia guaranitica ‘Black and Bloom,’ with its vibrant deep blue flowers and unique black anthers, is a favorite of hummingbirds (it’s often one of the last plants in the garden still blooming when their food supply is becoming scarce). In the Pacific Northwest, salvia emerges in late spring when it starts to warm up. A sunny site is optimal, but this perennial will bloom even in part sun.

Perovskia atriplicifolia (Russian Sage)

This drought-tolerant perennial thrives in soil that is less than perfect. Varieties like ‘Blue Jean Baby’ are about 36″ tall while the straight species can easily reach 48″ in height. Russian Sage looks great planted en masse or at the back of perennial border where it adds a tall, unifying element. Smaller forms like ‘Denim ‘n’ Lace’ mix well as a contrast to other drought-tolerant perennials. Plant these smaller varieties with Lavender, Salvia, and Lamb’s Ears (Stachys bizantina) or Daisy Bush (Brachyglottis greyi) to create a medley of soft shades of blue, purple, violet and silvery gray.

The Most Versatile Plants For Any Garden

Posted on by

If the plants in your garden aren’t looking quite the way you’d like, it doesn’t necessarily mean your green thumb needs a tune-up. You may be able to increase your rate of success by choosing plants that are more versatile and easy to grow. Some of the best choices are broad-leaf evergreens (evergreen plants that do not have needles or bare cones). These reliable workhorses thrive in a range of conditions. They’re so attractive that you’ll find even among the sophisticated garden palettes of experienced gardeners and designers.

Some broad-leaf evergreens to consider:

Choisya ternata (Mexican Orange Blossom) — Glossy, deep green leaves and a lush, bushy habit make this plant ideal for a low hedge or backdrop planting. Lots of small pure-white flowers compliment the foliage during summer. Choisya grows fast and can be shaped with regular hand pruning or allowed to grow free-form with only occasional shaping—you just want to avoid shearing them. Mexican Orange Blossom thrives in full or part sun, but languishes in shade. ‘Sundance’ has glossy bright golden-yellow foliage that needs sun to maintain its vibrant color. A garden standout, it provides many opportunities for dramatic combinations with other plants.

Aucuba japonica (Japanese Aucuba) — A dense mounding habit and glossy leaves make Aucuba ideal at the back of a shady border where its large ovate leaves will reflect light. Green-leaf Aucuba in deep emerald makes a rich backdrop for blooming perennials and other plants with colorful foliage. Aucuba ‘Picturata’, with golden-yellow variegation, will brighten a shaded woodland garden or pop as an accent plant. All Aucuba do best in full shade, and afternoon sun is to be avoided.

Escallonia — Escallonia are woody bushes with small leaves on twiggy stems. They range in size from compact and uniform to large and arching. They can be planted en mass as an informal hedge or screen. The tidy dwarf forms of Escallonia integrate well with mixed plantings. Alongside dwarf conifers, their small flowers make a nice contrast. Escallonia blooms profusely during the summer and its flowers are a favorite of bees. It will grow almost anywhere except in shade.

Viburnum davidii (David Viburnum) — Handsome dark-green foliage, small white flowers in spring, and small, deep-blue berries make Viburnum davidii a plant for all seasons. This is good plant to use for creating drifts or mass plantings in the context of a larger garden. Its substantial foliage will provide continuity and structure in a perennial border or mixed ornamental planting. Once out of favor due to over-use in the 1970s, this plant has made a comeback for good reason — it will grow in sun or shade and thrives in most soil types. It’s also low maintenance, needing only occasional thinning.

When Is The Ideal Time To Plant?

Posted on by
Acer griseum (Paperbark Maple)

Fall’s cooling air and still-warm soil are ideal for establishing new transplants. Perennials and evergreens alike can establish root systems before winter—and they require less water as the weather cools down and precipitation is more likely.  

If you are not ready to plant but garden projects are on your mind, fall and winter are great times to think about changes to your garden that would make it more enjoyable at this time next year or plan a new one.

Last spring I wrote the following, and it’s worth repeating now:

Consider making a list of goals for your garden and prioritizing them in case you can’t get to everything you would like to do this year. A garden log is an easy way to stay on track, measure your progress, and celebrate your accomplishments. You can add notes throughout the year as new ideas come to mind.

Gardens are built over time, improving as they mature, and benefitting from adjustments along the way.

Here are some basics to consider when setting out your priorities:

  • Screening and privacy. Do you have the coverage you want when deciduous trees lose their leaves?
  • Circulation. Are pathways and patios in the best location? Is it easy to walk the entire garden and keep your feet dry?
  • Structure. Are garden focal points and plant groupings positioned to provide good views from inside the house as well as in the garden?
  • Winter color. Do your perennial borders need something added to create dormant season interest? Would evergreen color and texture add depth?
  • Outdoor living. Would a covered outdoor structure create a quiet, dry place to get out of the house and enjoy your garden on a rainy winter day?

Plant Selection: form + function

Posted on by
Queen residence, Seattle WA

It’s prime time for Pacific Northwest Gardens so almost everywhere one looks there is something blooming or succulent new foliage unfolding.  If your garden isn’t in on the party, take note of what seems lacking and take pictures when you see plants that inspire you – they might just work in your landscape design.  At trip to a nursery is a good way to to see what is in season, but buying plants without a plan will not  necessarily result in a sustainable and cohesive long term plan.  So a little restraint can go a long way if you are looking for lasting improvements in your garden (think: going to the grocery store on an empty stomach without a shopping list).

The concept of right plant, right place is popular for a reason – successful plant selection is based on consideration of numerous factors that result in plants that thrive and a garden that has interest throughout the seasons.  If your garden needs a more comprehensive renovation or if you are planning a new one, before plant selection, come practical considerations like circulation, space planning and what features you require to suit your functional needs and aesthetic desires.  These factors along with site conditions will inform plant selection (think: brains and beauty). 

Here are some basics to consider once you are ready to select plants for your garden:

  • Screening and privacy. Do you have the coverage you want when deciduous trees lose their leaves?
  • Structure. Is there enough evergreen color and texture to add depth and create dormant season interest? 
  • Color. Do you have favored color palette? Are perennials and bulbs used to add seasonal color? 
  • Repetition. What plants provide continuity, create a rhythm and connect different parts of your garden.

What’s Down This Fall?

Posted on by
Acer palmatum ‘Purple Ghost’

With the arrival of much needed rains, it seems that we may not have an Indian Summer in the Pacific Northwest this year. Another sure sign of fall, I saw the first mushroom of the season clinging to the root of a spent tomatoe plant when pulling it up to discard it. Some perennials in your garden may also be looking spent, but others, like Rudbeckia, many types of Salvia and Asters will continue to bloom until frost.

With shorter days and cooler temperatures ahead, it may seem like time to to turn the focus toward indoor activities. But any gardener knows, the real work of making gardens begins now. Fall is one of the the best times to evaluate your landscaping and make changes. Maybe you are ready for an overhaul or just want a new look. Some types of plants are best planted in the fall and will grow roots until the ground freezes so, come next summer, they need less water to thrive. Even if you don’t intend to take any action right away, fall and winter is a good time to plan changes to your garden to implement next spring. Taking pictures each season allows you look back and see what is working best, record your successes and watch your garden mature. Also note which areas need a boost in order to look better at this time next year. If you are working with a garden designer, sharing these images is a good way to start a conversation.

A garden that starts with structural plant elements (good bones) will look good all year long and may become the focus during late fall and winter when branches are bare, perennials are dormant and most blooming plants are not producing flowers. For beginners this is a good place to start and build from. Or, if your garden has never had a plan or lacks unity, looking at it through this lens may be eye opening and give you some ideas about where to focus on or where to get help.

With thousands of plants to choose from, it may seem like an overwhelming task to select plants that look good and support your overall landscape plan. Identifying the type plants you favor is a good place to start. With that information, a garden designer can figure out which ones will thrive in your garden and how those can fit into a cohesive plan.

I hope this blog post helps you get started thinking about enhancing your garden. If you are not a gardener or don’t have the time, you can work with a landscape designer to be able to enjoy the beauty and benefits of curated outdoors spaces.

Extend Summer Color with Perennials

Posted on by

After the dog days of summer, the landscape can begin to look a little peaked. Fall-blooming perennials are a great way to add a fresh splash of color that will extend garden blooms to the first frost and beyond. Plant fall-blooming plants among summer-blooming perennials and annuals for a seamless display of color that can start in early spring and last through November.

Rudbeckia hirta ‘Cherry Brandy’

These garden mainstays flower reliably, year after year. Unlike annuals and biennials, which live for only a year or two, perennials are permanent plants that need only periodic division and replanting. This is about as low-maintenance as it gets! Some plants are semi-evergreen; others go dormant and die to the ground at the end of each season, and then reemerge from the roots the following year. Note that most perennials that bloom in the summer and fall require a full-sun location.

Here are some of my favorites for summer/fall color:

  • Rudbeckia hirta ‘Cherry Brandy’. A type of Black-eyed Susan, these are large deep maroon-red flowers with a dark chocolate center. A sturdy plant to 24″ tall.  Full sun, does best with ample moisture.
  • Sedum spectabile ‘Brilliance’. Waxy, Soft blue-green rounded leaves and deep rose-red blooms. Full sun, drought tolerant.
  • Asters (many, many cultivars). Sturdy plants covered with small daisy-like flowers. An array of growth habits and colors to choose from. Full sun, drought tolerant.

Late summer is the best time to reevaluate how perennials are working in your garden. Choosing them carefully can maximize bloom season and refresh the garden. If you are not ready to add plants now, note which areas could use some attention — but realize that the selection will be best now, while the plants are blooming. They may be hard to find out of season.

This is also the time to look to broad-leaf and coniferous evergreens for color, texture and structure during the wintertime.

Got Deer?

Posted on by

Deer enjoy some of the ornamental plants we grow in our gardens as much as we do, so if you are designing a garden in an area where deer are present, there are some key factors to consider.

Deer populations are thriving in the Puget Sound region. You’ll find them in the wooded suburban areas where they enjoy an abundance of food and have no natural predators. Some people think deer are adorable and others find them a nuisance, but what we can agree on is that they won’t be going away any time soon.

By planning ahead and making intelligent choices, you can minimize the effects of deer on your garden.

I won’t go into detail about deterrents, but you can search online for “deer-proof” and “deer-resistant” plants, as well as deer-fencing or other solutions. There has been much research done and there is an abundance of good material that can be found online or in books. Look at several sources, as recommendations vary.

For a less aggressive approach, here are my own top tips for creating a garden that can survive contact with our local deer:

  • Try planting in masses. This decreases the chances that all of one variety will be eaten at one time.
  • If you crave summer color, try vigorous, fast-growing perennials that can tolerate or benefit from being cut back midseason. Deer nibbling may act as “trimming” and plants may grow in fuller and stronger than before. This was the case in a client’s yard in Port Townsend, WA—a place know for its robust deer population. We were able to successfully grow Rudbeckia fulgida (black-eyed susan).
  • Plant many different species of plants and repeat throughout the garden. Deer may sample (as if at a smorgasbord), but get distracted and move on rather than consuming all of one single plant (no doubt one of your favorites).

A new garden is fascinating place for curious deer and they may be fickle and erratic. Deer may nibble on new plants once and then leave them alone. They may pass up a plant that they’ve eaten in the past.

However, keep in mind that there are some plants that are very likely to attract deer. For instance, a lush-looking bed of hosta can quickly turn into a salad bar. And a plump lily bud (just ready to pop into bloom) might just be a sweet treat for dessert.

Some trial and error is involved and it’s not a perfect science. If you absolutely don’t want to experiment with plantings, you still have plenty of options. Some deer-resistant design options include a rock garden, a dry riverbed, stepable ground covers and dwarf conifers.

I am experimenting with a number of strategies to keep ahead of the deer. One of these is containing a garden within a border of barberry and then planting a favorite food of deer, like lillies, on the outside. The idea is that the deer will be satisfied with the hosta and won’t want to push through the barberry perimeter to get to the main garden. I’ll keep you posted on how this turns out—and I’d love to hear about your experiences with deer.
