Herbaceous Plant Profile: Solidago rugosa

Author: Rebecca Stuart

Features: The pigment from the flowers can be used for dying yarn4. This plant serves as a food source for pollinators and can attract them to the area12. This plant has been mistakenly blamed for being the cause of hay fever while the real culprit is ragweed12.

Siting: Solidago rugosa is a rhizomatous plant that will spread and self-seed in the garden. It will do best in an area that gives it room to spread due to its width19. It is a hardy plant that can do well in full sun, part-shade, and a wide variety of soil types19.

Care: Plant crown at soil level18. At planting, water the roots and surrounding area slowly and deeply. Keep soil moist until plant is established, then apply enough water to thoroughly moisten the root zone when the soil is dry or during drought. Modify water recommendations to reflect site drainage and rainfall. Apply 3" of mulch over the planted area. Do not allow mulch to touch the plant stems18. Once established the plant can self-seed which can save time from replanting19. While it is a low maintenance plant the grower must watch out for disease12.

Pests: This plant does not typically have any pest issues. It can be susceptible to rust, powdery mildew and leaf spot12.
