RED PILLAR® Rose of Sharon

Zone: 5, 6, 7, 8, 9 Exposure: Full Sun Height: 10-16' Width/Spread: 4-5'

All the splendor of the Pillar series with a narrow habit, but with delicious dark red coloring in the flowers. Each bullseye-like bloom on Red Pillar® rose of Sharon is like a magnet for human and hummingbird visitors alike. Together the dramatic coloring and upright habit make it an exciting specimen. In that position, its plentiful two-toned flowers can create a color palette for the garden. The dark red, pink, and even creamy white (if you include the stamen) tie the space together with a tropical, romantic, or formal aesthetic, depending on which plants you pair with it. Red Pillar also creates quite an impact when planted in a group as a screen for a patio or as a hedge between neighbors. A wall of flowers is better than most views.

Why grow Red Pillar rose of Sharon?
– Useful tough nature, great resistance to deer, and tolerance of drought, salt, and heat.
– Interesting upright habit.
– Low maintenance care with no need to prune to shape.


Light: Thrives in full sun. When planted in an area that gets less than six hours of direct sun each day, it will not flower as prolifically and long stems may bend more.

Soil: Enjoys any type of well-draining soil. Will underperform if it’s overwatered or in a soggy spot.

Water: Average water needs while establishing. Demonstrates good drought tolerance after its first year in the ground.

Fertilizing: Has a pretty high nutrient need. After its first year in the ground, apply a fertilizer each spring after the soil has thawed. Use a formula with a nutrient ratio that is highest in the middle number (# – # – #), this is Phosphorous and it will help the plant develop flowers.

Pruning: Regular pruning is not necessary. It maintains a naturally graceful upright habit on its own. If any shaping is desired, do so in the early spring.
