Long, billowing mounds of lavish flower power make a gigantic statement, no matter where you place them. Add an instant "pop" of tropical appeal with the Mars Madness Hardy Hibiscus (Hibiscus x 'Mars Madness' PP #27838). It's easy to create a backyard paradise with these modern cultivars. The magenta-red petals have hints of pink and a darker center with yellow tubular stamens.

The flowers start in mid-summer and last through fall. Butterflies, hummingbirds, and essential pollinators adore the saucer-shaped blooms for their nectar! No one can miss the vivid, six-inch blooms! They add both vibrant color and a wonderful texture with veins that are deeply impressed into the petals.

They'll become an incredible accent, even before the blooms get started. New foliage emerges coppery-purple, then ages to olive green with a copper overlay! With its unique foliage and flowers, even a single plant makes the most of a space. They'll grow to form a full, billowy look with large maple-like leaves and outstanding flowers produced from the top to the bottom.

You'll love them for the gorgeous drama they bring. This Hardy Hibiscus is an improved modern cultivar of native Rose Mallow...and is a durable, sustainable choice for your landscape! Hardy throughout USDA growing zones 4 to 9, these perennials grow just over 4 feet in height and 6 feet in width.

Try them as an amazing backdrop for Butterfly Gardens. Magenta blooms and dark foliage will turn any perennial planting into an event! Add some serious pizzazz to your foundation planting! Flank either side of your front door with a pair of them in oversized containers.

If you have the room, expand your planting with a new curved garden bed. Use three or more of these dynamic Hardy Hibiscus in a grouping to maximize your curb appeal.

#ProPlantTips for Care:

Grow Perennial Hibiscus in part shade or full sun, they need at least four hours of sunlight a day. Morning sun is preferred to quickly dry the foliage from any overnight dew. Plant in soils that drain quickly, although they'll put up with a periodic rainy spell. Container-grown plants should have plenty of drainage holes...and avoid using saucers underneath. Although well-drained soil is best, they'll put up with periodically dry soils, too. Provide a regular schedule of water to keep them hydrated and happy. Add a three-inch layer of mulch over the roots to cut down on surface evaporation.

For best results over time, give your Hardy Hibiscus a sheltered spot. It will still need good air circulation, but out of the worst of the winds to keep the blooms from getting tattered or torn! Remove spent flowers once they are finished for a trim and tidy look. Prune back each of the stems to ground level in early spring. Please be patient, as they are one of the last plants to get started. By late spring, you'll start seeing new stems emerge from the roots.

  • Full Sun or Partial/Afternoon Shade
  • Average Well-Drained Soil
  • Can Be Grown in Average, Moist to Wet Soils
  • Deadhead After Flowers Fade
  • Dies To The Ground Each Winter - Prune Early Spring
  • Very Cold-Hardy & Heat-Tolerant
