Favorite or New Plant

Prairie Rosinweed
With repeated hot and dry summers, our desire to add more drought-tolerant plants to the gardens increases. Prairie plants, which so often have deep tap roots, will be among those that come to the fore. One of the most dramatic of our native plants is prairie rosinweed or prairie dock, Silphium terebinthinaceum, with the one common name referring to the aromatic stem resins. The plants form a clump of huge oval to heart-shaped, dark green leaves to 2 feet long. In midsummer, thin flower stalks rise to 8 feet, topped by 3-inch wide yellow, daisy-like flowers, with the seed heads attracting birds, especially goldfinches. There are no serious insect or disease problems with prairie rosinweed, but you must be patient as the plants are slow to establish, sometimes taking two or three years to begin flowering.
