About Oakleaf hydrangea
Hydrangea quercifolia, commonly known as Oakleaf Hydrangea, is a deciduous shrub native to the southeastern United States, distinguished by its large, lobed leaves resembling those of an oak, which turn stunning shades of red, purple, and bronze in autumn. It produces showy conical clusters of white flowers that mature to pink, providing significant seasonal interest to the garden. It is an excellent choice for woodland edges, mixed borders, or as a specimen plant where its attractive foliage and blooms can be admired.

Care tips
It prefers a location with partial shade, especially in warmer climates where the afternoon sun can scorch its leaves. It needs well-drained soil, rich in organic matter, and with a slightly acidic pH. Keep the substrate consistently moist, but avoid waterlogging, especially during dry periods. A common mistake is pruning at the wrong time; pruning should be done right after flowering, as it blooms on old wood.
