Add a late-summer standout to your landscape with Hibiscus syriacus 'Diana' (Rose of Sharon 'Diana'). This hardy, deciduous shrub produces large, pure white hibiscus-like flowers through summer, often when many other shrubs are finished. The blooms show beautifully against dark green foliage, and the plant can be maintained as a full shrub or trained into a small tree with thoughtful pruning.
Give your plant room to mature: it typically reaches about 60-96 inches tall, with a broad, upright form that fits well into mixed borders, foundation plantings, hedges, or as a specimen. Plant it where it receives full sun for best flowering, though it will also tolerate partial shade. Flowers form on new wood, so you can prune in late winter or early spring to shape the plant and encourage strong new growth for summer bloom.
Hibiscus syriacus 'Diana' is widely adaptable once established. Provide average moisture during establishment, then water during extended dry spells. Choose a well-drained site and apply a layer of mulch to moderate soil moisture and temperature. As with many woody shrubs, consistent seasonal care and occasional renewal pruning help keep the plant vigorous, full, and floriferous year after year.
