Lobelia

Cardinal Flower

In the dog days of August, just when the border is not looking so lively, this genus of colorful, stately selections rejuvenates the garden with spectacular leafy flowering spires, attracting crowds of eager hummingbirds. Perfect in meadow plantings, these sturdy herbaceous perennials appreciate a well drained site, a light winter mulching, rich, moist soils and partial shade in warm climates, except for Lobelia tupa and Lobelia laxiflora, which like it hot and on the dry side.

Dressed in a crisp snowy white, the profusely flowered tapers of this Lobelia stand in sharp relief to its dark green foliage. A newly selected form of our U.S. native, ‘White Candles’s small, compact stature keeps its lift all season, lending a clean and classic look, especially when partnered with Geranium ‘Orion’.

Blooms July–August.

Size: 18" – 20" high x 18" wide.

Hardy to zone 5.

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.
