Description

Rosinweed (Silphium integrifolium) is a bold native perennial known for its thick, lance-shaped leaves and bright yellow, sunflower-like blooms. Standing 2 to 6 feet tall, it thrives in open meadows, prairies, and pollinator gardens—offering structure, color, and vital nectar for bees, butterflies, and other pollinators.

This low-maintenance wildflower prefers full sun and well-drained, loamy soil, but it’s adaptable to a range of conditions. Its deep roots help it withstand drought, making it a resilient choice for native landscaping and prairie restoration.

Rosinweed is ideal for gardeners looking to support local wildlife while adding long-lasting color and texture to their landscape.
