Full Blast® Rose of Sharon Tree

Full Blast® is a large-flowered Hibiscus syriacus selection, ‘Resi’, presented here in tree form. It produces lavender blooms across a long spring-to-fall season and grows about 8–10 feet tall. ## Planting and Display The upright plant has large, lavender flowers that bring a tropical look to a hardy landscape. Its tall profile is suited to a sunny specimen spot, a mixed border, or a screen planting. The Chicago Botanic Garden reports a mature height of 8–10 feet and hardiness in Zones 5–9; no mature spread is provided in that profile.

The flowers contrast with the plant’s green foliage and give the tall shrub a long season of color. Rose of Sharon is deciduous and can be grown as a shrub or small tree.

Leave room for the upright crown to develop, and use light pruning to maintain the intended tree outline. Protect the roots from prolonged waterlogging and water new plantings regularly as they establish.
