In June and July the Oak Leaves (Hydrangea quercifolia) wears a long, conical clusters of white flowers on stem tips. The deep green, deeply lobed oaklike leaves make an attractive, contrasting background foil for the flowers, which last for about three or four weeks. In the fall, these leaves blush scarlet deep burgundy. Native to the open forests of the American Southeast, oak hydrangeas can grow well in full sun exposures if certain conditions are met.
An oak leaf hydrangea shrub growing in the full gamut of the garden exposures from full sun to shade. The habit, flower and autumn leaf color performance are directly related to the light conditions. Normally an oak leaf hydrangea is planted where it receives four to six hours every day shade – partial sun to partial shade situation. Up to six hours of direct sunlight gives the leaves, promotes a compact, bushy habit and flowering time calls. Sun rays in autumn accentuate the red foliage.
Full sun effects
If the soil is too dry or infertile, an oak leaf hydrangeas planted in full sun often shows signs of stress. Growth disturbances lead sheet scorch or brown leaf margins when too much hot sun basking the system and inadequate soil moisture exists. However, full sun creates the bushiest shrubs, and leads to a greater number of flower clusters and intense autumn color compared to those grown in shady garden locales.
If the garden soil is sandy and mostly dry, not the oak leaf hydrangea plant in full sun. The fast draining sandy soil its not enough moisture to search for the best investment and growing. Conversely, if the garden soil is a rich loam or clay with abundant organic matter, soil moisture are likely much higher. An evenly moist soil helps offset any heating or drying effects of a full sunlight. It leads to root rot and plant death – never plant oak leaf hydrangeas in a muddy soil or floods.
Regions of the U.S., long endure hot summers or where the summer is usually lacking rain, it is better to plant the oak leaf hydrangea in a partially shaded border. Cooler summer climates such as. In the Pacific Northwest or the northeastern quarter of the country, not as intense sunlight in southern latitudes Oakleaf hydrangeas can handle in the northern U.S. full sun much better.
