Description
The garden hibiscus (Hibiscus syriacus), also known as shrub hibiscus or Sharon rose, is a summer‑green flowering shrub with funnel‑shaped flowers in white, pink, red, purple, and blue‑violet. It grows upright to a height of 1.5 to 2.5 m and is one of the last shrubs to bloom, flowering into late summer when many other garden plants have already faded. In the garden it can be planted as a solitary plant, in groups, or as a flowering hedge, varieties such as ‘Oiseau Bleu’ (blue‑violet) or ‘Woodbridge’ (purpur‑pink) are particularly vigorous and prolific in blooming. As a winter‑hardy shrub it remains permanently in the bed and accompanies your garden for years.
Care instructions
Plant the garden hibiscus in a location ranging from full sun to partial shade, warm and sheltered from wind, more sun yields richer blooms. The soil should be loose, well‑draining, and humus‑rich; heavy clay soils should be loosened with sand and standing water must be avoided. Protect young plants during the first two to three winters with a mulch layer of leaf litter or straw, as they gradually build up full frost tolerance. A pruning in early spring (March/April) is well tolerated and promotes the formation of new flowering shoots.
