Lobelia ‘Grape Knee-Hi’

Hybrid Lobelia

USDA Zone: 5-9

Plant number: 1.328.150

The perennial Lobelias have upright spikes of large flowers, not at all like the more familiar trailing types grown in hanging baskets. They are terrific plants for the moist garden, adapting well to ‘wet feet', but growing equally well under average conditions. This beautiful, compact selection bears rich grape-purple flowers through late summer and fall, over a clump of dark-green leaves. In colder regions plants should be mulched well for the winter. Nice for cutting. Attracts butterflies. USPP#13264: unlicensed propagation prohibited. CAUTION: Harmful if eaten.
