Mirabilis nyctaginea (Michx.) MacMill.
Heartleaf four o'clock
Nyctaginaceae (Four-O'clock Family)
Synonym(s): Allionia nyctaginea, Mirabilis collina, Oxybaphus nyctagineus
USDA Symbol: MINY
Mirabilis, in Latin, and Maravilla, in Spanish, both mean marvelous, which the flowers certainly are. They open in the shade of the late afternoon. This lovely native species is a close relative of Common Four-oclock (M. jalapa), a plant originally from Mexico, popular in gardens since the Aztecs, and now commonly escaping into the wild; it has purple, yellow, or sometimes white or variegated flowers generally not longer than 2 1/2 (6.5 cm).
