  • Description

  • Notes

This Lobelia is a very showy, shrub-like perennial, growing to 2'-4' tall. It spreads by underground rhizomes. It has bright, tubular, orange-red summer flowers with yellow orange throats. It can tolerate low water conditions. Hummingbirds love this Lobelia. It thrives in wet soil but does not require it. This is the most tolerant of Lobelias for full sun sites.
Planting: 1. Dig a hole 1" less the depth and 2 times the width of the container. 2. Fill hole with water, let soak. 3. Set root ball in hole. 4. Fill hole halway with native soil and water. 5. Finish backfilling hole, build basin and water.
