Grow in rich, medium to wet soils in full sun to part shade. Needs constant moisture. Tolerates full sun in northern climates, but appreciates part afternoon shade in hot summer climates of the lower Midwest and South. In nature, lobelias are typically found in wet areas such as bogs, moist meadows and along streams. Divide clumps in spring. Root mulch should be applied in cold winter climates such as St. Louis to protect the root system and to prevent root heaving.
'Cotton Candy is well-suited to very moist soil conditions, but does surprisingly well in average garden soils as long as those soils are not permitted to dry out.
Lobelia is a genus of about 370 species of annuals, perennials, shrubs and some aquatics. They grow in tropical and temperate areas worldwide but many come from North, Central and South America.
Genus name honors Matthias de l'Obel (1538-1616), French physician and botanist, who with Pierre Pena wrote Stirpium Adversaria Nova (1570) which detailed a new plant classification system based upon leaves.
'Cotton Candy' is a hybrid lobelia introduced by Thurman Maness. It is a vigorous, clump-forming perennial which features erect, terminal spikes (racemes) of cotton candy pink flowers on alternate-leafed stalks typically growing to 2-3' tall. Stalks rise up from basal rosettes. Flowers are two-lipped, with the three lobes of the lower lip appearing more prominent than the two lobes of the upper lip. Long late July to September bloom.
No serious insect or disease problems. Snails and slugs may damage the foliage.
Effective in moist areas of woodland/shade gardens, wet meadows or along streams or ponds. Also adds late summer bloom and height to borders as long as soils are kept uniformly moist.
