I think the winter hardiness zones on this plant need to be adjusted. I planted 3 of them 2 years ago—this will be their 3rd summer. I live in Idaho, zone 6A. Their first summer, all three put on 3-4 feet of growth and had beautiful flowers. Unfortunately after during their first winter, all three died down to the bottom 6”. I fertilized them and babied them all summer and they put on several feet of new growth. Then I wrapped them in burlap and leaves for the winter. Unfortunately one completely died and the other 2 both died down to the base. 3 stars because they are a beautiful plant and they grow fast. Just not hardy in zone 6.

You've never seen a rose of Sharon like this before!
Purple Pillar® is a totally unique rose of Sharon: it naturally grows as a narrow column instead of a wide, spreading plant. It gets to be just 4-5' (1.2-1.5 m) wide and 10-16' tall! Think of what you could do with that: screens, hedges, patio containers. Anywhere you need a little privacy and/or color in a narrow space, this plant is a great choice. Like most all hibiscus, it will do best in full sun. It is hardy to USDA Zone 5.
In summer, each stem is packed along its entire length with purple blooms. This unusual columnar habit makes it a real space saver - if you thought you didn't have enough space to grow rose of Sharon, Purple Pillar is perfect for you. Try it in containers, or flanking your front door, or simply as a quirky accent in your landscape.
