Plants that tuck themselves in for bedtime exhibit a natural behavior known as nyctinasty. Scientists know the mechanism behind the phenomenon: In cool air and darkness, the bottom-most petals of certain flowers grow at a faster rate than the upper-most petals, forcing the flowers shut.
Just so, how do you keep Portulaca blooming?
Make sure portulaca is planted in full sun; if it is planted in shade it may not bloom. Also, too much fertilizer can cause portulaca plants to have bright beautiful leaves and no flowers. Portulaca does not like too much fertilizer.
Moreover, do portulaca flowers bloom all summer?
At heights of no more than 6 inches, portulaca, also known as moss rose or sun plant, is a low-growing stunner with cactus-like blooms that last all summer. The blooms, in bright jewel tones of orange, pink, purple, yellow, red and white, grow on thick, succulent foliage.
