Four O'Clock (Marvel of Peru)
Mirabilis jalapa
Family Nyctaginaceae
Est. zones 2-11

A delightful old-fashioned bush with its own clock — fragrant trumpet flowers opening in the late afternoon and staying open all evening to feed hawk moths and hummingbirds, often in several colors on one plant. Fast and easy from seed, drought-proof, and it makes tubers you can lift and store like dahlias, growing bushier each year. Note the seeds and roots are toxic if eaten.
