For those looking for perennials that bloom in August, consider the
Delosperma florbunda, a trademarked ice plant with succulent, gray-green leaves and bright pink flowers with white centers. Not only does this plant cover itself in flowers, but if given enough light, it will do so all summer long.
Like almost all ice plant, this one requires excellent drainage and not too much water. Drought tolerant, it grows to a height of four to six inches and will spread into a nice circle about a foot in diameter. Even though cold hardy, in our climate, the plant will most likely die back for the coldest part of the winter, but don't forget it's there, because it will probably come back in the spring to offer another year of beauty.
Ice plant is a good choice for rock gardens, container arrangements, and along the front edge of borders.
