'Diamonte Coral Rose' (Diascia intergerimma) is an improved variety of Diascia, a South African native plant relatively unknown five years ago. It features a profusion of exquisite inch-wide five-lobed tubular flowers with backward-pointing spurs. A frost-tolerant annual, the plant grows to 10 inches high and spreads to 18 inches wide. It's ideal for containers, where if planted near the edge it will cascade. It blooms over a long season, thriving in both heat and cooler temperatures.
