Hydrangea quercifolia 'Snow Queen™' (oakleaf hydrangea) brings four-season interest with bold, oak-shaped leaves, showy white summer flower clusters, and rich fall color. You will love how the upright panicles hold their form, then age to a soft tan that can linger into winter for added texture.
Plant it where you can appreciate the foliage: deep green leaves in summer shift to red and purple tones in autumn. Mature size is typically about 48-72 inches tall with a broad, mounded habit that can spread 72-96 inches, so give it room to develop its natural shape.
For best performance, grow your oakleaf hydrangea in moist, well-drained, organic-rich soil. It handles full sun to part shade; in hotter locations, afternoon shade helps keep foliage looking its best. Mulch to keep roots cool and evenly moist, and water during dry spells while the plant is establishing.
Because this hydrangea flowers on old wood, avoid heavy pruning in late winter or spring. If you need to shape or reduce size, prune right after flowering. This is also a great choice for woodland edges, mixed shrub borders, and native plantings where its bark, blooms, and fall color can shine.
