Perennial Hibiscus, commonly known as Rose Mallow
Perennial hibiscus are hardy perennials in zones 4-9. Their large stature and dinner plate sized blossoms make them the talk of the neighborhood from midsummer to early fall as they flaunt their tropical looking blossoms. Hummingbirds and pollinating bees are attracted to the colorful flowers, but deer typically pass them by.
Growing Tips for Perennial Hibiscus:
- Grow perennial hibiscus in full sun to light shade.
- Never let them dry out—consistent moisture is critical.
- Apply an extended release fertilizer once in late spring when new growth emerges.
- This plant comes up later than most perennials. Don’t fret! It will return reliably every year.
- Leave the woody stems standing until spring, then cut them down to 6” tall.
- New growth will emerge from below ground, not on last year’s stems.
