Mirabilis multiflora

Quick Characteristics:

Mirabilis multiflora (Torr.) A. Gray or Colorado Four o'clock is a species native to the south-western states of the USA. Typically for section Quamoclidion it has several of its bright purple flowers per involucre. The somewhat darker throat is notably wider than in Mirabilis jalapa. The sprawling plant has silverish and slightly succulent leaves, as it is adapted to dry, desert-like conditions. The species is among the most hardy of the genus and has survived -15 °C with only minor snow cover in southern Germany. You need to be patient in spring, as it doesn't emerge before early May.
