More about this plant
A rose of Sharon that naturally grows as a narrow column instead of a wide, spreading plant, reaching 10 to 16 feet tall but only 4 to 5 feet wide. It blooms prolifically along its entire length with semi double purple flowers from summer through fall above green three lobed leaves that turn gold in fall. It wants full sun and good drainage, has low water needs once established, and needs minimal pruning thanks to its columnar habit. It draws bees, butterflies and hummingbirds.
