Silphium integrifolium, commonly known as Entire-leaved Rosinweed, is a striking, native perennial that adds bold texture and color to the garden. This robust, clump-forming plant features large, deep green, oval-shaped leaves and produces vibrant, yellow daisy-like flowers atop sturdy, 4-6 foot tall stems. The showy blooms of Silphium integrifolium emerge in flattened, umbrella-like clusters from mid-summer through early fall, creating a striking visual display. The large, golden-yellow petals surrounding a dark center disk are irresistible to a variety of pollinators, including bees, butterflies, and birds. Thriving in full sun and well-drained, average to poor soil, Entire-leaved Rosinweed is an adaptable and drought-tolerant perennial. Its tall, architectural habit and bold flowers make it an excellent choice as a focal point or statement plant in prairie-style gardens, meadows, and naturalized settings. The lush, green foliage also provides year-round interest, even after the blooms have faded. Easily propagated by seed or division, Silphium integrifolium is a resilient native that requires little maintenance once established, making it a valuable addition to a wide range of landscape designs.
