streambank wild hollyhock
Iliamna rivularisAlso known as Mountain Hollyhock, River Mallow, Wild Hollyhock
Streambank wild hollyhock produces tall, leafy stalks crowned with delicate pink-to-lavender blossoms reminiscent of garden hollyhocks. Growing along western North American montane streams, burned hillsides, and moist forest glades, it relies heavily on wildfire or physical scarification to break its hard seed coat and stimulate germination. Its attractive blooms attract native bees, butterflies, and hummingbirds throughout midsummer.
