A US National Arboretum introduction, Ruby Slippers Oakleaf Hydrangea is designed to have a compact rounded form but with plenty of flower power producing loads of large, uniform elongated clusters of flowers that start out white, change to pink, and ultimately to a deep rosy pink. The beautiful velvety Oak-leaf like foliage is a rich medium green for much of the year but deepens to purples and reds in fall.
The peeling bark makes itself known in winter but soon disappears under springs new cloak. Provide the Oakleaf Hydrangeas with a soil that is moist but well-drained. Once established in the landscape they require little extra attention and can become a cornerstone of almost any landscape. Some of the most beautiful plants we've seen were in Washington, D.C. but the ones at Stephen F. Austin are absolutely amazing. Images courtesy of the US National Arboretum website.
Good drainage in a moderately loamy, humus rich soil and a consistent supply of moisture during dry periods are key considerations to success for Hydrangea quercifolia
. An organic mulch goes a long way toward helping maintaining consistent and even moisture levels and once the Oakleaf Hydrangea is well established it is more resistant to periodic dry spells. In cooler more northerly latitudes the Oakleaf Hydrangea is known to tolerate more sun. As you move into hotter climates more shaded conditions are generally preferred for this species and its cultivars. Filtered shade and afternoon shade are preferred over heavy shade. Where the Oakleaf Hydrangea gets some sunlight it will typically have the most intense fall foliage colors. Checkout 'Oakleafs are Homesteading Along Sara's Branch
