Thimbleweed

Anemone cylindrica

Anemone cylindrica, known as Thimbleweed, is a perennial herb reaching heights of 1 to 2 feet. It has deeply lobed leaves and produces greenish-white flowers from June to August, followed by cylindrical seed heads resembling thimbles. Thimbleweed thrives in prairies, woodland edges, and along roadsides, preferring well-drained sandy or loamy soils. Thimbleweed is appreciated in landscaping for its unique seed heads and adaptability, making it suitable for prairie gardens and naturalized plantings.

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.
