Four O'Clocks for Descanso Gardens
Four O'Clock (Mirabilis jalapa). Upright herbaceous annual growing large tuberous roots. It may survive as a perennial, becoming dormant in our milder winters. Many hybrids are available in shades of red, pink, yellow or white. They bloom in the evening and are very fragrant. White varieties are lovely in gardens seen in the evening. It reseeds prolifically into the garden. Keep the seedlings pulled to control it. Seeds and roots are poisonous. Gophers don't like it. The red varieties attract hummingbirds.
