Say hello to the sunny Silphium integrifolium, otherwise known as wholeleaf rosinweed, just one of the many native plants available this year at our Native Plant Sale. This herbaceous perennial is native to Eastern and Central North America and generally blooms from July to September. A wonderful attractor of birds and butterflies, it is know to grow quite easily in average, medium moisture to well-drained soils in full sun. It can even tolerate a bit of drought once rooted. This sunflower look-alike usually grows 2 to 3 feet tall, but can reach heights up to 6 feet. Find it, and more, on Saturday, April 7 at Ruffner Mountain! Plant Natives. Grow Diversity.
