Luna™ White Hardy Hibiscus produces enormous, dinner-plate-sized flowers that bring a tropical look to temperate gardens. It reaches 2 to 3 feet tall with a 2 to 3 feet spread, working well in perennial borders and mixed plantings. Plant in full sun to partial shade for the best results. It thrives in zones 4 through 9. Expect visits from pollinators, butterflies, and hummingbirds throughout the growing season. As a native plant, it supports local ecosystems and needs very little extra care once established.
