Hibiscus syriacus ‘Amplissimus’
The Double Red Hardy Hibiscus is a deciduous shrub with stunning fully-double blooms that look like red-purple peony flowers. It grows 6 to 10 feet tall, with a narrow, upright form no more than 5 feet wide. The rich-green glossy foliage is always attractive, and a profuse display of blooms begins in summer and continues into fall. Grow it in garden beds or large tubs, and this tough and reliable plant is a perfect follow-on to crape myrtles, which enjoy similar growing conditions.
- Gorgeous red blossoms like peonies
- Blooms from summer to fall
- Easy to grow in hot and dry conditions
- Ideal shrub for planters or beds
- Authentic heirloom plant
Full sun is perfect for the Double Red Hardy Hibiscus, but it will take a little partial shade as well. It grows in any well-drained soil, preferring rich soils with regular watering, but thriving anyway even in heat and drought. It only takes a simple spring pruning to keep it neat and blooming for months, and pests or diseases are almost never a problem. Even deer leave it alone, and it resists urban conditions and coastal salt as well.
- Plant Hardiness Zones 5-9
- Mature Width 4-6
- Mature Height 6-10
- Soil Conditions Well-Drained Soil
- Sunlight Full Sun to Partial Shade
- Drought Tolerance Good Drought Tolerance
The hardy hibiscus is also known as the Rose of Sharon, and like true roses it comes in forms with single flowers, but also in rarer forms with amazing double flowers. A double helping of ‘good’ has to be ‘great’, and that’s how it is with the Double Red Hardy Hibiscus. Its big pom-poms of bright red-purple petals grow all along the stems of this reliable bush, looking like peony flowers, and they make a wonderful display all through late summer and into fall. If you are looking for easy-to-grow plants that deliver blooms when most other bushes have stopped flowering, then you can’t ignore hardy hibiscus. For reliable blooming with very little attention, they can’t be beaten, and for something really different, the Double Red Hardy Hibiscus will rival rose bushes (and be a fraction of the work).
