Dimorphotheca pluvialis: The Delicate White African Daisy
Dimorphotheca pluvialis, commonly known as White African Daisy, Cape Marigold, Weather Prophet, Cape Rain-daisy, Ox-eye Daisy, Cape Daisy, or Rain Daisy, belongs to the Asteraceae family of plants. This charming species has captured the hearts of gardeners with its elegant blooms and vibrant colors.
Unveiling the Background and Discovery of Dimorphotheca pluvialis
Dimorphotheca is the former name for Osteospermum, but it now refers specifically to the annual species. Unlike Osteospermum, Dimorphotheca pluvialis exhibits a different color range, showcasing hues of white, cream, yellow, and orange. This captivating flower has gained several common names, including Rain Daisy and Weather Prophet, due to its unique behavior of closing its flowers at night, on cloudy days, or before the rain.
Native to South Africa and Namibia, Dimorphotheca pluvialis boasts narrow, sometimes toothed leaves. The plant was first discovered in its native regions, where it thrives in diverse habitats. To prolong the flowering season, it is recommended to deadhead the flowers by removing spent blooms.
Characteristics and Blooming Season
Dimorphotheca pluvialis is an annual plant that typically grows to a height of 8-12 inches (occasionally up to 16 inches). It features daisy-like flowers with white rays tinged with purple beneath and yellowish-brown center disks. These delightful blooms grace the landscape from summer to fall, particularly in cool summer climates. However, flowering may slow down in the hot and humid summers of regions like St. Louis. The mesmerizing phenomenon of the flowers close at night and in certain weather conditions adds an enchanting touch to this captivating plant.
