Luna White Rose Mallow

Hibiscus 'Luna White'

The Story

Plant Bio

Hardy hibiscus are robust, shrub-like perennials known for their enormous, tropical-looking flowers that bloom from mid-summer until frost.

'Luna White' is a compact cultivar prized for its huge, pure white, dinner-plate-sized flowers, each with a striking central red eye.

Uses & Benefits:

The massive, tropical-looking white flowers create a stunning focal point in any garden setting. Its compact size makes it ideal for containers on patios or decks, bringing a touch of the exotic to small spaces.

This plant's tolerance for wet soils makes it an excellent choice for rain gardens or low-lying areas where other plants might struggle. It can be used to create a temporary summer hedge or screen.

The large, nectar-rich flowers are a magnet for pollinators, including bees, butterflies, and hummingbirds, supporting local ecosystems and adding life and movement to the garden.
