Grass-leaved Goldenrod

Euthamia graminifolia

Grass-leaved Goldenrod is a perennial that grows 2 to 4 feet tall, featuring narrow, lance-shaped leaves and dense, flat-topped clusters of small, yellow flowers that bloom from July to September. It is commonly found in moist to wet habitats such as meadows, ditches, fens, and shores, preferring sandy to gravelly soils and full sun. This species is valuable for pollinator gardens, attracting bees and butterflies, and is suitable for wetland restorations and naturalized areas.

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.
