Pale-spike Lobelia (Lobelia spicata)

Pale-spike Lobelia

Lobelia spicata

Pale-spike Lobelia is a slender, upright perennial reaching 1 to 2 feet in height. It is commonly found in wet meadows, open woodlands, and savannas, preferring moist soils but can be found in dry soils as well. The pale blue to lavender flowers appear on tall spikes in mid to late summer. This species is a valuable addition to prairie plantings and pollinator gardens, as it provides nectar for bees and butterflies while thriving in a range of soil conditions.

Sowing Information

Sow seed onto a firm, weed-free seedbed. Hand-broadcast seed making two perpendicular passes for even coverage. If planting a mix, broadcast the grass component first and lightly rake/drag it into the top 1/8–1/4" of soil. Next, broadcast wildflower/forb seed and press it into the soil surface (with a roller/cultipacker or the back of a rake) to ensure good seed-to-soil contact. After seeding, apply a very light layer of clean, seed-free straw (or other weed-free, site-appropriate mulch) to reduce erosion and retain moisture without smothering seedlings. A good rainfall or thorough watering will help settle seed and mulch and improve germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
