Native to the United States, Hydrangea quercifolia (Oakleaf Hydrangea) is a very handsome and versatile deciduous shrub which provides a spectacular show all year round. Named after the shape of its beautiful leaves, it produces a profusion of magnificent grapes of creamy-white flowers, up to 12 in. (30 cm), in late spring and early summer. Lasting about 3-4 weeks, the elongated flower clusters gradually turn pink as fall approches. In fall, the foliage of deeply lobed, oak-like leaves steals the show by turning bronze, crimson or burgundy, making this flowering shrub one of the most attractive shrubs for the fall garden. As the leaves fall, they expose the rich brown exfoliating bark.
- Oakleaf Hydrangeas typically grow up to 6-8 ft. tall and wide (180-240 cm).
- Cold-hardy, Oakleaf Hydrangeas can endure harsh winters and severe cold. They are excellent substitutes for Mophead Hydrangeas (Hydrangea macrophylla) in colder climates.
- Full sun or part shade lovers, Oakleaf Hydrangeas prefer fertile, medium moisture, well-drained soils. Best in partial shade in hot summer areas but they tolerate full sun in cooler, moist climates.
- Oakleaf Hydrangeas are great candidate for mass plantings, hedges, mixed shrub borders, as a backdrop or accent plant. Flowers are very attractive in dried arrangements.
- Since Oakleaf Hydrangeas flower on previous year's growth, they should be pruned shortly after flowering is complete.
- Can cause mild stomach upset if ingested and contact with foliage may aggravate skin allergies.
