Lobelia siphilitica

3–5' tall. Sometimes called Blue Cardinal Flower.

Handsome native wildflower of stream edges and bogs. Similar habit to its more famous red cousin, but with blue-violet flowers that are beloved by the bumblebees. 

Considered a short-lived perennial, but in good conditions it will reseed and naturalize nicely. Seeds need damp open ground to germinate.

Plant along the water’s edge or in consistently moist garden soil. Full sun to light shade. Mulch to reduce weed competition in the first year. Zone 3.

Additional Information

Herbaceous Perennial Plants

When you receive your order, open the bags and check the stock immediately. Roots and crowns should be firm and pliable. Surface mold is harmless and will not affect the plant’s future performance. Store plants in their packaging in a cool (35–40°) location until you are ready to plant. If it’s going to be awhile, you can pot up your perennials.

Do not plant bare-root perennial plant crowns directly outdoors before danger of frost has passed. Wet and/or cold conditions for an extended period may cause rotting.
