Desert Four O'Clock

Mirabilis multiflora

Plant Details:

Plant Type: Perennial
Plant Family: Nyctaginaceae
Plant Description: This large Utah native plant spreads horizontally from a single large tap root. It has lush green leaves all season, with attractive magenta blooms appearing from mid-summer through frost. Requiring little or no additional water and not performing well if overwatered, this plant is a "must have" for any low-water landscape. Stems detach easily from the root at the end of the growing season for easy fall cleanup.


Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
