Description

A totally unique rose of Sharon! There's really nothing like it - Purple Pillar® rose of Sharon is the first columnar hibiscus. Purple and red semi-double flowers appear all summer long. The narrow fastigiate habit gives it unlimited landscape potential: narrow hedges, screens, formal gardens, entry ways, and decorative containers. However you use it, Purple Pillar hibiscus makes a bold choice that's truly low-maintenance. Winner of the Silver Medal at the Plantarium show.
