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.
Have you grown weary of Lobelias, whose lovely blooms reside above a rather untidy base? If so, you may be interested in Dan Heimís brilliant solution to this age-old challengeóa small-statured L. cardinalis and L. syphilitic backcross, known as ĎGrape Knee-Hií. Painted with vibrant deep purple hues, the long lasting and freely flowering, tightset spikes crown upright stalks and good-looking compact foliage that stands on its own all season long.
Size: 2' 0" high x 15" wide.
Hardy to zone 6.
