A fast growing, easy to grow plant that will flower from early-summer through fall. They get about 30" tall and about 24" wide. The flowers are very fragrant, about 2" across, and are yellow, white, pink and red. The flowers open up around 4pm (name's sake) and stay open all night. Regulars at these flowers are hummingbirds, butterflies, bee's and hawk moths. These plants form tubers underground and will reemerge early next spring. They can also spread through dropped seeds. A little fertilizer mid-summer along with medium water is about all the care these plants need. These are one of my favorite plants. If you want colorful blooms, summer through fall with very little effort, Four O Clocks are for you, and me. Also, deer resistant.
