Wahlenbergia species have dispersed widely, even to oceanic islands, and there are four species known from the island of St Helena, including the now extinct species W. roxburghii.
Large blue flowers dominate this indigenous annual. Growing up to 80cm tall and flowering spring through summer this plant copes well in most conditions.
