Very bushy, vigorous plants growing to 60 cm (2') in height. Bright, clear flowers of white, red, yellow, rose and lilac open later in the day although they will open somewhat earlier on cloudy days. Flowers are fragrant and attractive to butterflies, hummingbirds and bees. Due to their size and bushiness, Four O'Clocks are quite suitable as an informal flowering hedge. Plants produce tubers that often grow large enough to be lifted and stored over the winter much like dahlias. The tubers can be replanted the following spring after the danger of frost has passed. Four O' Clocks are prolific bloomers and often self sow.
