The individual flowers may not last for more than a day or two, but they open in succession leaving the plant in continuous bloom. In the winter burgundy rosettes remain evergreen.

Sundrops are easily grown in average, medium moisture, well-drained soils in full sun. They prefer heat and dryish soils. They will tolerate poor soils, light shade and some drought. Although sundrops tolerate poor soils, they do better when the soil is supplemented with organic material. Sundrops will grow in partial shade, but flowers best in the more sunny spots. Once a popular pass-along in old fashioned gardens, sundrops are enjoying a renaissance with the growing popularity of native plants and wildflowers. Moths pollinate the flowers, particularly Sphinx moths. Other occasional visitors include the Ruby-Throated Hummingbird, honeybees and bumblebees. The insects seek nectar, although some of the bees collect pollen.
