Bee introduces how to plant

Plant Perennial Lobelia Seeds: Sow seeds in cell packs or two in. pots, press into soil but do not cover. Needs light to germinate. Kept at 75°F., germination is usually within 4-5 weeks. If not, put container inside a zip-lock bag and refrigerate for 4 weeks. Then return to 75°F. until germination occurs.

Probably the brightest red wildflower, hummingbirds love them, especially Ruby-Throated hummingbirds. The nectar-rich flowers also attract Swallowtail, Sulphur and a host of other butterflies.
