Hydrangea Arborescens

What is the plant

The inflorescence is a corymb. The showy, sterile flowers are usually absent or if present they are usually less than 1 cm in diameter. Flowering occurs May to July. Fruit is a ribbed brown capsule about 2 mm long; many are produced. The leaves are large (8 to 18 cm long), opposite, serrated, ovate, and deciduous. The lower leaf surface is glabrous or with inconspicuous fine hairs, appearing green; trichomes of the lower surface are restricted to the midrib and major veins. The stem bark has a peculiar tendency to peel off in several successive thin layers with different colors, hence the common name "sevenbark". Smooth hydrangea can spread rapidly by stolons to form colonies

How to Care for the Plant

Water
These varieties of hydrangeas are surprisingly drought-tolerant. If the plant is being grown in full sun, give it a thorough watering weekly until it is well established. A layer of mulch will help to retain soil moisture.
Pruning
Prune Incrediball hydrangea plants anytime between the first hard frost of fall and early spring. Depending on your preference, you can make pruning cuts right down to the ground, as new shoots will be generated.
Fertilizer
Fertilize the hydrangea once in the spring with a 15-30-15 formula—or one that's similar—to coax out the plant's blooms.

Sunlight
Incrediball hydrangea grows in full sun to partial shade, and the latter is preferable in dry climates. If you live in the south, give the plant some shade in the hot afternoon hours.
Soil
Plant the Incrediball hydrangea in rich garden soil that will keep the roots moist. Unlike some other hydrangeas, Incrediball's flower color is not affected by soil pH.
Temperature
Hovers around 70 degrees Fahrenheit during the day and just below 60 degrees Fahrenheit at night. However, during the bud development stage, the hydrangeas need six weeks of temperatures below 65 degrees.
