Perennial Hibiscus is a winter hardy perennial that is known for its distinctive large dinner plate size flowers. Colors vary from white, pink, yellow/cream and red. Hibiscus are best used as a focal point in a bed planting or as a hedge-like background in a larger planting.
Don't be surprised if you don’t see any sign of growth until the first to middle of June!
*You may actually want to mark them in the fall to be able to find them in the spring.
- Plant in full sun or a very light shade.
- Prefers high organic matter in soil.
- Will tolerate moist conditions but prefer drying out in-between watering.
- Due to the large size of canes, staking is recommended during early growth.
- Hibiscus are hardy to Minnesota, but they do require a 6-8 inch covering of Marsh Hay or mulch over the crown of the plant.
- The best time to cover is AFTER the first hard frost.
- Cut back canes to 6 inch from the ground AFTER the first hard frost.
- Usually takes until June 1 to June 15 to see the stem emerge from the soil.
- Blooms normally develop around August 1st and bloom until the first frost.
Suggestions for Success:
- Grows to an average height of 6 feet each season and 4-6 feet wide.
- Cover your Hibiscus with about 6-8 inches of Marsh Hay in the fall.
- Place plant markers by your Hibiscus so you remember where it was.
- Use Stakes to keep the tall stems from falling over.
