False Dandelion

Agoseris glauca

Agoseris glauca, known as False Dandelion, is a perennial herb reaching heights of 8 to 15 inches. It produces basal rosettes of lance-shaped leaves and solitary yellow flower heads resembling those of dandelions, blooming from late spring to early summer. This species thrives in prairies and meadows preferring well-drained soils. False dandelion blooms around mid-summer and its bright yellow bloom is especially attractive to pollinators. It has a similar flower to the common dandelion, which is non-native, but can be distinguished by its linear toothless leaves.

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.
