Erigenia bulbosa is the botanical name for a perennial wildflower also known as harbinger-of-spring. It is native to North America and a member of the same plant family as carrots. It produces delicate white blooms with dark brown anthers during late winter or early spring. Erigenia bulbosa grows to a height of less than 1 foot and occurs naturally in shaded, woody sites. It performs well in almost any soil that retains even moisture.
Gather Erigenia bulbosa seeds in middle spring to late spring, after they have dried completely.
Prepare a planting site by removing weeds and grass. Loosen the soil 8 to 10 inches deep with a spade.
Plant the seeds at a depth equal to 1/2 their length. Moisten the soil lightly right after planting. Continue to water the site when the top 1/2 inch of soil dries out.
Spread 2 to 3 inches of organic mulch around the plants when they are 3 to 4 inches tall. This protects the roots, prevents weeds and eliminates the need for fertilizer, as nutrients are released when the mulch decomposes.
Keep the soil lightly moist at all times, but avoid over-watering, which could lead to disease.
Prune away damaged and unsightly leaves when you notice them.
Cut the foliage of erigenia bulbosa back to soil level during summer.
Renew the layer of mulch in early fall to ensure protection of the roots during winter months.
