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.

May rebloom if cut back after flowering.

Noteworthy Characteristics

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.

'Sparkle DeVine' is a clump-forming hybrid perennial lobelia which features erect, terminal spikes (racemes) of large, lavender to purple flowers on alternate-leaved stalks typically growing to 36" (less frequently to 48") tall. Stalks rise up from basal rosettes. Flowers are 2-lipped, with the three lobes of the lower lip appearing more prominent than the two lobes of the upper lip. Long August to September bloom period. In nature, lobelias are typically found in wet areas such as bogs, moist meadows and along streams. This hybrid cultivar is more adapted to garden conditions and will live longer than the perennial species lobelias.


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.

One of the longer blooming lobelias.
