Not all lobelia are of the trailing habit, and 'Riviera Sky Blue' lobelia is a case in point. Forming a compact mound only six inches tall and about as wide, this variety boasts dainty sky blue flowers from early spring into the fall. 'Riviera Sky Blue' will add a tight spot of true blue color on dense green foliage to borders, container planters, and hanging baskets. Regular watering and fertilizing will keep this lobelia fresh and "blue-tiful" throughout the summer.
