Modern yards require modern plants. This is one of the very best!

Strongly vertical accent shrub Proven Winners® Color Choice® White Pillar® Rose of Sharon (Hibiscus syriacus 'Gandini van Aart' PP28892) offers semi-double, pure white blooms from mid-summer through fall.

Best of all? The skyscraper form makes such a useful accent in the landscape.

Think of how you could use that in your garden! Screens by the A/C unit, hedges around the pool, containers flanking the front door or garden gate. This is a literal punctuation mark in your evergreen beds and perennial borders.

A cultivar of native Rose Mallow/Hardy Hibiscus, White Pillar can be used in a million spots in your yard. Semi-double blooms entice hummingbirds and butterflies to come for a visit.

The pure white blooms produce very few seeds. Let them glow for you in the moonlight, and give you a cool-toned visual appeal all day.

Healthy, dark green foliage makes a contrasting foil for the large, tropical-looking blooms. The pristine sophisticated color makes a wonderful partner for other plants.

Keep things crisp and elegant with an all-white color palette. Or, use White Pillar as a helpful backdrop for red-hot perennials, or cool-toned smaller shrubs.

Low-maintenance Rose of Sharon shrub starts delivering fabulous blooms just as other flowering shrubs are done for the year. Extend your season of flowers for both landscape use and in beautiful cut flower arrangements.

Grow this tall, skinny variety in the ground in either full sun or partial shade. Or...use them as a magnificent "Thriller" in extra-large outdoor containers.

Add White Pillar Rose of Sharon and enjoy a thousand-fold increase in pure drama. It's an instant shot of high-end, designer style.

How to Use White Pillar® Rose of Sharon in the Landscape

Place one near the side of your front door as a durable accent. Those lean, tall good looks will be a terrific feature all year-long.

Try a pair on either side of your garden gate. Every time you pass between them, you'll revel in a grand sense of entrance.

Take this concept and expand on it. Add a double row in a showy allée along the length of your side yard. Why not make a feature out of a boring, ho-hum area?

Spacing these plants is just as versatile as everything else about these cool plants. For a solid screen, measure 18 inches from the center of one plant to the center of the next.

For an allée, increase the spacing between plants to four or five feet. Allow 12 to 15 feet between the rows.

Repeat their use along the back of your perennial or shrub border to produce a very effective backdrop. Extend the height of your hardscape fence with a solid "living fence" for welcome privacy.

Go all out with an eye-catching garden feature by alternating White Pillar with Purple Pillar Rose of Sharon. Go ahead and some fun in your space!

#ProPlantTips for Care

Give them at least four hours of sunshine a day. More sun means more flowers!

Apply a medium amount of water on a regular basis for the best results. Add a three-inch layer of mulch to cover the root system.

New plants need careful attention to water. Once your plants are established, they'll handle a bit of drought. Container-grown plants will always need a medium amount of supplemental water.

White Pillar blooms on new wood, so prune it in early spring. You can shape the sides and tip prune to control the height at that time.

Deer don't prefer the taste, but they are hungry little buggers. If there are deer in your area, apply deer repellent on planting day. Follow reapplication instructions on the label.

Fall in love with the strong structure and flower power of White Pillar® Rose of Sharon. Order yours ASAP, these are a big sell-out risk.

Looks GREAT

Received this today. The plant arrived fully leafed out, which is awesome since this particular plant is notoriously late leafing out. It was quite large, which I was skeptical of, since even Proven Winners doesn't sell this particular variety larger than in a gallon pot, but this arrived in a full 3 gallons and is nearly 4 feet tall!
