Impatiens

From a genus comprised of hundreds of species, the following easily grown shade lovers offer both foliar and floral interest. Impatiens omeiana is surprisingly hardy, while the other selections are quite tender; all look compelling in either a pot or a garden bed.

<i>Impatiens namchabarwensis</i>

Hailing from the world’s deepest canyon in the remote Himalayan shadows of Mt. Namcha-Barwa, this wondrous 2003 discovery introduces perhaps the bluest flowering perennial Impatiens to date. Hallmarked by yellow-etched white throats and bright ultramarine or vivid blue-violet flared petals, whose colors vacillate with exposure, the extraordinary bountiful blooms appear nearly year round, conjuring images of exotic flying birds amid shiny serrated green leaves. Highly coveted, hard-to-find and perfect for containers, inside or out, Blue Diamond is a frost sensitive temptress that can be grown as a self-sowing annual in cold climates and as a perennial in milder areas, where it adores cool summers, even moisture and filtered light, and abhors hot sun and frosty nights.

Blooms April–October.

Size: 18" high x 18" wide.

Hardy to zone 10.

Current Staff's Favorite Plant

Helianthus 'Sheila's Sunshine', Persicaria 'Summer Dance', and Selinum wallichianum

Helianthus ‘Sheila’s Sunshine - P-0461

The sunflower was once an emblem of the Sun God of the Incas. Our sunflowers tolerate a wide range of garden soils, attract bees, and make great cut flowers. Blooms early August – October.

Persicaria ‘Summer Dance’ - P-1312

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please. Happiest in semishade with ample moisture. Blooms August–November.

Selinum wallichianum - P-1406

This refined Himalayan beauty happens to be one of our favorite perennial umbellifers. With untold elegance, infinitely divided leaves craft a delicate, lacelike transparency. The compact yet airy green canopy is framed by distinctive, purple-infused branching stems that elevate a charming, late season display of white flattened umbels.

Subduing the riotous array of summertime blooms, it seldom needs staking, and appreciates a well draining moist niche. Blooms June–August.
