Kopper King Hardy Hibiscus

Availability: Out of stock

The Kopper King Hardy Hibiscus (Hibiscus x moscheutos 'Kopper King') has some of the biggest flowers available on the perennial market today. They commonly grow to dinner plate size - a foot or more across! These Hollyhock-like flowers have five petals and come in shades of light pink, with red central eyes and red veins throughout the petals.

Pollinators will come from far and wide to sip nectar, and Hummingbirds will appreciate the elongated tubular stamen that acts as a perch while they visit each of the prolific blooms! Not only will Kopper King become smothered completely in huge flowers, but new blossoms keep popping up all summer until frost!

These pink flowers stand out like beacons against the deep copper-red serrated foliage, too! Growing into a neat-looking 3-4 foot tall and wide mound, Kopper King is fast-growing and space-saving without ever looking leggy! These Rose-Mallow hybrid Hibiscus are considered Hardy Hibiscus, meaning that they grow in colder weather areas throughout USDA growing zones 4 to 9. This Hardy Perennial Hibiscus won't fade or shrink in the summer sun!

#ProPlantTips for Care:

Normal garden soil and plenty of sun are all that Hardy Hibiscus plants really need to provide years of interest in your garden! Any well-drained soil will due but a 3-4 inch thick layer of mulch that holds in moisture and insulates the root system. Deadhead after the flowers fade, and cut the stems back to the ground each early spring. Deer resistant, heat and cold hardy, few plants bloom in the late season without fading like these fantastic perennial plants!

  • Full Sun Perennials
  • Any Well-Drained Soil
  • Tolerates Average to Wet Soils & Occasional Drought
  • Deadhead After Flowers Fade & Prune Early Spring
  • Wonderfully Cold-Hardy To Zone 4 & Heat Tolerant To Zone 9
