Description

Lobelia siphilitica. This perennial produces racemes of 2-lipped violet-blue flowers in late summer and autumn. They are borne on 2-3 foot stalks.

Cultivation

These frost-hardy to somewhat frost-tender plants are best grown in well-drained, moist, light loam enriched with animal manure or compost. Most grow in sun or part-shade but resent wet conditions in winter. Prune after the first flush of flowers to encourage repeat flowering, and fertilize weekly with a liquid manure during the season.
