Growth Facts

The Story

Rose Moon Hibiscus resembles the old Rose of Sharon bushes that seed around, spawning lots of seedlings that need to be pulled up. However, this Hibiscus is different. It was bred in England by nurseryman David Tristram to be superior to all of those old varieties. Tristram started his breeding program in 1985 by crossing a Rose of Sharon Hibiscus with another Hibiscus species. Over the years, he crossed the resulting hybrids, searching for outstanding plants. When he found Rose Moon in 2002, he knew he had a winner. Its flowers were enormous, and the plants produced no seed.

The Details

Incoming! Rose Moon’s pink blossoms are stamped in the middle with a red bullseye. The circle is a target for hummingbirds, who come zooming in for the flower’s sweet nectar. Their aeronautics will entertain you all summer.

How to Grow

Rose Moon Hibiscus is easy and satisfying to grow even for novice gardeners. Choose a site with all-day sun. Rose Moon will also grow in part shade, but will put out fewer blooms there. This plant likes light soils and needs good drainage, but it doesn’t want to dry out completely. Irrigate weekly if no rain falls to supply just the right amount of water and get your plant off to a great start. Rose Moon will also respond favorably to an annual application of Bower & BranchElements™ Fertilizer. This is one of the slowest plants to leaf out in the spring, so be patient! Pruning can be accomplished at any time of the year.
