Power Perennials

Posted on July 30, 2024 by michael

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.

Hillside Hideaway, Seattle WA

Posted on July 11, 2020 by michael

The owner of this Seattle home, a garden enthusiast, wanted to upgrade the landscaping and asked me to come up with a plan.

The sloped lot on a wooded hillside provided both opportunities and challenges. I created a series of terraces along the side of the house transforming an awkward slope into a place for a new patio and plantings. The terraces function as a series of connected garden rooms that flow together, making it easy to move about the site.

On the home’s entry level, we enlarged the main patio using architectural slabs that reflect the clean lines of the house and blend seamlessly with the existing concrete. Stepable groundcover adds visual interest and natural stone risers provide a graceful transition to the woodland garden beyond. The natural flagstone patio underfoot, lush plantings and mature trees overhead, gives one the feeling they have been transported far from the city. Beyond the woodland, visible from the patio during summertime, organic juniper timbers border a collection of shade-loving perennials evergreens. A combination of native, woodland and ornamental plants keeps the palette interesting.

Ballard Neighborhood, Seattle WA

Posted on June 14, 2020 by michael

A lovingly restored Ballard bungalow deserves a fitting garden. The owner, a master gardener, loves plants and hired me to create a comprehensive plan to solve problems like screening the apartment house next door. The pathway is made of repurposed brick from the original chimney and recycled stepping stones add to the relaxed air. I focused on plants that create structure and continuity with emphasis on seasonal focal points. The result: there is always something interesting popping up or coming into bloom.

In the backyard, the dappled shade below a canopy of mature trees is ideal for the lively palette of this shade garden. Broadleaf shrubs and japanese maples provide structure and perennials create a lush spot for cool summertime dining or a weekend garden party. The owner has a flair for creating a casual vibe with repurposed items like a wooden dining set that has taken on a rustic patina adding to the organic feel of this garden.

: evergreens screen the apartment house next door

: planting the parking strip gives the illusion of a much larger front yard and adds instant curb appeal

: plantings in the parking strip effectively double the size of the front yard

: an informal pathway of wood chips leads to the backyard

: plantings on both sides of the house provide a seemless transition between garden rooms

: a woodland retreat awaits in the backyard

: stepable groundcover creates a luxurious carpet underfoot

: A combination planting ensures interest at ground level

Financial Center – Credit Union Headquarters, Seattle WA

Posted on June 11, 2020 by michael

The client purchased the building for its headquarters intending to renovate inside and out. The exterior landscape was outdated and overgrown and needed to reflect the modern, fresh image of its new owner. After exploring some preliminary design concepts with the client, in concert with the project architect and interior designer, a plan for a pedestrian courtyard was born. The new landscape includes usable outdoor space for the building’s inhabitants and fosters a sense of community. Plantings include Salal (Gaultheria shallon) and other Pacific Northwest native plants that reflect the company’s branding and local roots. Large boulders and the simplicity of mostly green foliage ground the structure and support its clean lines, giving it new relevance. Permeable pavers meet current storm water codes and reflect the grid pattern on the building while designating the plaza as separate from the surrounding sidewalks.

Lenten Rose, Snow Drops and Cyclamen are flowering now. It is a good time to think about adding these to your garden for next year.

It is also a good time for a stroll through The Washing Park Arboretum, Kubota Gardens and other local parks and botanical gardens to see what is blooming now. You will notice other plants and trees that stand out. Many extraordinary and colorful varieties of conifers and deciduous trees with intriguing bark are striking during the winter months.

Enjoy the view and fresh air or take notes and pictures if you are looking to update your garden and make it more “winter friendly”.

Back home, look at your own garden and decide what adjustments would make a show at this time next year.
