Silphium terebinthinaceum

  • Known for its sunflower-like bright yellow blooms that tower over the garden upwards of ten feet, this is a long-lived perennial that can stun for decades.

  • With preference to full sun, this plant sends a taproot up to fourteen feet into the soil making it extremely drought tolerant once established.

  • Thriving in full sun, it grows upright and dramatic with large, leathery, silver green foliage. Though slow to establish, one mature, it is low maintenance and persists in the garden for many years. It also spreads easily by seed.

  • A tall-grass prairie staple growing in the Midwest through New York.

  • Large leaves with a silvery sheer emerge in spring and grow quickly during warmer months. In late summer, flower spikes appear crowned with bright yellow daisy-like blooms that soar over the garden. Tall stems remain long after the flowers fade through winter.

  • Late-summer blooms offer an important nectar source for insects, while deep roots help stabilizing soils and enhance soil health by circulating nutrients found deep underground.
