Hydrangea Arborescens Flower Shape
The Arborescens species of hydrangeas are characterized by their flattened hairy clusters of flowers, which grow as corymbs at the end of the stems.
Growing Hydrangea Arborescens
Arborescens hydrangea can easily be grown in average, medium moisture, well-drained soils that offer partial shade. These hydrangeas may tolerates full sun but only if they are grown with consistent moisture. These plants dehydrate very easily and are intolerant to drought. If they don’t receive sufficient water the foliage on the plant will begin to decline and droop.
Surviving the Cold Winter
The plants need to be winterized in order to survive a harsh and cold winter. Flower blooms occurs on new wood, so the plants can be pruned back close to the ground in late winter. Pruning helps to revitalize and encourage vigorous stem growth in the spring.
Arborescens Plant Characteristics
The loosely and widely branched hydrangea arborescens typically grow 3 to 6 feet high and in a few cases up to 10 feet tall. The plants are native to moist or rocky wooded slopes, ravines, streambanks and bluff bases. They have grayish brown stems which are clad with opposite, broad egg-shaped to rounded, sharply toothed, dark green leaves with pale green undersides. The leaves will turn yellow in the fall. They produce tiny and mostly white fertile flower blooms in flattened hairy corymb clusters. The flowers will give way to dehiscent seed capsules which begin to ripen as the fall season sets in.
Insects and Diseases
The arborescent plants are not known for having serious problems with insect and diseases. Many species of hydrangea, including this one, are susceptible to bud blight, bacterial wilt, leaf spots, mold, rust and powdery mildew. Always keep a good watch for aphids, mites, scale and nematodes. Something that will help keep the plant healthy is pruning the stems back to the ground in late winter each year.
