Mirabilis nyctaginea

Wild four-o'clock flower cluster showing buds and an open flower.

Wild four-o'clock leaves are generally heart-shaped, resembling leaves of lilac.

Wild four-o'clock has a large branched taproot, making it nearly impossible to pull up.

  • The scientific name roughly translates to 'wonderful night-bloomer'. The common name, 'wild four-o'clock', refers to the time of day that this species will flower (around 4 pm).

  • Another common name, 'umbrella-wort', refers to the large papery bracts which form an 'umbrella' around the flower clusters and seeds.

  • Several Native American tribes used the root to reduce fever, cleanse wounds and relieve abdominal swelling.
