Know your hydrangeas.
- Big leaf macrophylla shade to part sun.
Hydrangea macrophylla is a species of flowering plant in the family Hydrangeaceae, native to China and Japan. It is a deciduous shrub growing to 2 m tall by 2.5 m broad with large heads of pink or blue flowers in summer and autumn.
- Petiolaris climbing part sun.
Hydrangea petiolaris is a vigorous woody climbing vine plant, growing to 30 to 50 ft (9 to 15 m) height and 5 to 6 ft (2 to 2 m) wide. It grows up trees and rock faces in its native Asian habitats, climbing by means of small aerial roots on the stems. The leaves are deciduous, ovate, 4–11 cm long and 3–8 cm broad, with a heart-shaped base, coarsely serrated margin and acute apex.
- Annabelle sun to part shade.
Easily grown in average, medium, well-drained soil in part shade. Tolerates full sun only if grown with constant moisture. Intolerant of drought, with foliage tending to decline considerably in dryish conditions. This species blooms on new wood, and may be pruned back close to the ground in late winter each year to revitalize and to encourage vigorous stem growth and best form. Plants may die to the ground in harsh winters. If not pruned back, any weakened and/or damaged stems should be removed in early spring.
- Oakleaf, sun to part shade.
Hydrangea quercifolia is a coarse-textured deciduous shrub growing to 8 metres (26 ft) tall with an open crown. The plant sprouts shoots from underground stolons and often grows in colonies. Young stems are covered in a felt-like light brown bark, and the larger stems have attractive cinnamon-tan-orange bark that shreds and peels in thin flakes.
The leaves are yellowish green to dark green on top and silvery-white underneath. They have three, five or seven pointed lobes and are 4–12 in (10.2–30.5 cm) long and almost as wide. They are larger versions some oak leaves, resembling Quercus species with lobed foliage. Plants in shade have larger leaves than those grown in sun. Hydrangea quercifolia leaves turn rich shades of red, bronze and purple in autumn that persist in winter accompanying the persistent dried flower-heads.
- Peegee, full sun to part shade.
Peegee hydrangea (H. paniculata) – Peegee hydrangea are the largest of the free-standing types, growing 15 to 20 feet high and 10 to 15 feet wide. Native to both China and Japan, Peegee hydrangea are hardy in Zones 3 to 8 and produce elongated white flower panicles that appear in late summer. Over time, Peegee hydrangeas can be trained to resemble trees.
