You'll love Proven Winners® ColorChoice® Purple Pillar® Rose of Sharon (Hibiscus syriacus 'Gandini Santiago') for its ability to squeeze into narrow spaces and smaller properties! When you don't have room to spread out… grow up! Columnar Rose of Sharon, also known as Althea, is easy to grow and a very low-maintenance, space-saving shrub!

Bold, semi-double blooms provide a dazzling accent! They're a gorgeous violet pink with striking red centers that feather and 'bleed' outward into the ruffled petals! These are like bullseyes and fine dining to bees, butterflies and even Hummingbirds that will flock to the garden! The flowers start popping in mid-summer and keep returning until fall!

This useful cousin of Hardy Hibiscus stays trim and tight, but puts on a lot of height! The graceful growth habit is strongly upright, reaching straight up to the sky. The bush produces few lateral branches, and most of the growth is pumped skyward. Purple Pillar® Rose of Sharon has been field-tested for high performance for many years by the Proven Winners® team.

Planting and Application:

Rise to the challenges of modern landscapes with the help of these best-selling plants. Where can you use this unique shrub to your best advantage? Add these tall, skinny, flowering shrubs to your garden and enjoy swoon-worthy blooms that keep coming from summer through fall.

Although the strongly vertical form adds a formal touch, the flowers from summer through fall soften Purple Pillar's® look. They look wonderful anywhere...from a hodge-podge cottage garden to a high-end commercial landscape! This variety is a thoroughly modern Rose of Sharon that fits small spaces. Use several plants in a row to help hide the neighbor's second-story bedroom window or add several throughout your yard to get the most from your space and call pollinators galore!

This columnar shrub can certainly grow into a marvelous flowering hedge. Use several at your property line for a "friendly fence", or add a row on the sunny side to brighten up existing evergreen trees. Try them in combination with other hedging plants, like Linebacker Distylium or Chestnut Hill Cherry Laurel. Create your own unique hedgerow, or use Purple Pillar® at either end of an evergreen hedge to open and close the experience.

Flowering "living walls" helps your landscape live large. Create a series of garden rooms for entertaining and a getaway destination spot just for you. How would you decorate a Secret Garden? Place a small garden statue, a fountain, or a mini Peach tree in the center. Don't forget a comfy chair and an outdoor table!

This could become a lovely backdrop for a perennial garden border or Butterfly Garden. You'll have many visitors to these fetching mid-season flowers that bloom at an opportune time for pollinators. Purple Pillar® can be planted 18 - 24 inches apart on center, measuring from the center of one to the center of the next. Stagger a double row behind it for a faster screen.

Just want to hide the more utilitarian features of your landscape? You'll love the effective screening delivered by this rugged plant. It stays lean and strongly vertical for an incredible focal point. Tuck one anywhere in the sun as a specimen. They can even be planted in extra-large outdoor containers!

  • Graceful, Upright Shrub & Green Foliage
  • Hummingbirds, Pollinators & Butterflies Love the Nectar-Rich Blooms
  • Starts Blooming When Other Shrubs are Done for the Season

#ProPlantTips for Care:

Plant these low-maintenance shrubs in full sun for the most blooms. You'll have the most flowers with at least six hours of direct sunlight a day. Rose of Sharon needs well-drained soil that sheds water quickly. Use a raised bed or container if your native soil retains water for a long time. Keep the roots a bit moist but never wringing wet for long. A three-inch layer of arborist mulch over the root systems keeps them happy and cool. Reapply regularly, and it will work to improve the condition of your soil over time.

Pay careful attention to your young plants, and those grown in containers. They'll need a regular schedule of medium water. Please protect your investment with supplemental water during extended droughts. Deadhead after flowering reduces the seedlings that tend to sprout and become a nuisance in some areas of the country.

In early spring, you can prune Althea to shape them or reduce height. We do recommend you allow them to fill out their naturally graceful full spread. Tidy them as you like, but shearing is perhaps a bit extreme. Renewal prune every 3-5 years to maintain vigor. Rose of Sharon shrubs are durable, providing years of service with a modicum of care. This exciting variety represents a huge leap forward.

  • Low Maintenance in Full Sun
  • Widely Adaptable in Any Kind of Well-Drained Soil
  • Moderate Moisture Needs & Appreciates Mulched Beds
  • Keep to the Height You Want With Spring Pruning
  • Field-Tested to be Easy to Grow
  • Tolerates Salt & Deer Don't Prefer the Taste

Tree Form vs. Shrub Form

The details make all the difference in a garden. At Naturehills.com, we understand that little things like what form a plant is can greatly impact how you plan your landscape. So before you buy, don't forget to check which form you're getting.

Tree Form:

These are plants that have one stem coming from the ground. Plants can also be considered single stem when lower branches are removed to raise the height of the branching to a more desired height. Sometimes, you will hear a tree form referred to as a single stem.

Shrub Form:

These are bushy plants with many stems and branchings close to the ground. They are referred to as shrubs or bushes and are often shorter than their tree forms.
