Hydrangea petiolaris | |
Hydrangea petiolaris, a climbing hydrangea (syn: Hydrangea anomala subsp. petiolaris), is a species of flowering plant in the family Hydrangeaceae native to the woodlands of Japan, the Korean peninsula, and on Sakhalin island of easternmost Siberia in the Russian Far East. [1]
Hydrangea petiolaris is sometimes treated as a subspecies of the closely related Hydrangea anomala from China, Myanmar, and the Himalaya, as Hydrangea anomala subsp. petiolaris. The Hydrangea anomala species differs in being smaller (to 12 metres (39 ft) ) and having flower corymbs up to 15 cm diameter. The common name Climbing hydrangea is applied to both species, or to species and subspecies.
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. [1] 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.
The flowers are produced in flat corymbs 15–25 cm diameter in mid-summer; each corymb includes a small number of peripheral sterile white flowers 2.5–4.5 cm across, and numerous small, off-white fertile flowers 1–2 mm diameter. [1] The fruit is a dry urn-shaped capsule 3–5 mm diameter containing several small winged seeds.
Hydrangea petiolaris is cultivated as an ornamental plant in Europe and North America. Climbing hydrangea is grown either on masonry walls or on sturdy trellises or fences. It is at its best where it gets morning sun and afternoon shade, however it can tolerate dense shade, [1] and is therefore often selected for shady, north-facing areas with little or no sun. Its clinging rootlets are not as strong as some other wall-climbing vines, and so is often anchored with supplemental gardening ties. Its outward-reaching side shoots can be pruned back to a pair of buds to espalier it flatter against its support. When pruned during flowering, the blooms are useful in bouquets.
It can also be grown as a ground cover, to eventually grow over an area of up to 200 square feet (19 m2). [1]
It is an USDA climatic Zone 4a plant, so it can resist temperatures down to between -34.4 °C (-30 °F) and -31.7 °C (-25 °F).
The young leaves of climbing hydrangea are edible when cooked. Tasting like cucumber, they're sometimes added to Miso in Japan. [2]
‘Hydrangea’ is derived from Greek and means ‘water vessel’, which is in reference to the shape of its seed capsules. [3]
A vine is any plant with a growth habit of trailing or scandent stems, lianas or runners. The word vine can also refer to such stems or runners themselves, for instance, when used in wicker work.
Hydrangea, commonly named the hortensia, is a genus of more than 70 species of flowering plants native to Asia and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs 1–3 m tall, but some are small trees, and others lianas reaching up to 30 m (100 ft) by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.
Hydrangea anomala, the Japanese climbing-hydrangea, is a species of flowering plant in the family Hydrangeaceae native to the woodlands of the Himalaya, southern and central China and northern Myanmar.

It is a small- to medium-sized, multi-stemmed, deciduous shrub up to 2 m (7 ft) tall that is native to the eastern United States.
Hydrangea cinerea, the ashy hydrangea or gray hydrangea, is a small to medium sized, deciduous shrub up to 3 m tall; its natural range is interior regions of the southeastern United States. Its common names reflect the ashy or gray appearance of the undersides of its leaves, which results from a dense pubescence.
Vinca major, with the common names bigleaf periwinkle, large periwinkle, greater periwinkle and blue periwinkle, is a species of flowering plant in the family Apocynaceae, native to the western Mediterranean. Growing to 25 cm (10 in) tall and spreading indefinitely, it is an evergreen perennial, frequently used in cultivation as groundcover.
Hakea petiolaris, commonly known as the sea-urchin hakea, is a shrub or small tree with cream-coloured and pink or purple flowers and woody fruit. It is endemic to the south west of Australia, occurring at the coastal plain, jarrah forest and wheatbelt regions, often at the ancient granite outcrops of Western Australia.
Agapanthus praecox is a popular garden plant around the world, especially in Mediterranean climates. It is native to the Kwa-Zulu Natal and Western Cape provinces of South Africa. Local names include agapant, bloulelie, isicakathi and ubani. Most of the cultivated plants of the genus Agapanthus are hybrids or cultivars of this species. It is divided into three subspecies: subsp.praecox, subsp. orientalis and subsp. minimus.
Eucomis autumnalis, the autumn pineapple flower, or autumn pineapple lily, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae, native to Malawi, Zimbabwe and southern Africa. It is a mid to late summer flowering deciduous bulbous perennial. The flower stem reaches about 40 cm (16 in), rising from a basal rosette of wavy-edged leaves. The green, yellow or white flowers are arranged in a spike (raceme), topped by a "head" of green leaflike bracts. It is grown as an ornamental garden plant and can also be used as a cut flower.
Chrysocephalum semipapposum, commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. C. semipapposum produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. C. semipapposum is often confused with Chrysocephalum apiculatum or 'yellow buttons', due to their similar appearances. C. semipapposum has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. C. semipapposum is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered everlasting has many uses, including as a source of nectar for butterflies, cut flowers or as an addition to a garden.
