Climbing hydrangea: pictures of the plant, care and advice on how to grow it in pots or in the garden. Botanical sheet of the Hydrangea petiolaris.
L'climbing hydrangeait is native to the forests of Japan, Korea and the easternmost area of Russia.
The scientific name of the species isHydrangea petiolaris. In China thisplantit is not considered a species in itself but as a subspecies of the Hydrangea anomala, Hydrangea anamola subsp Petiolaris.This classification arises due to the similarities of the two plants. Either way it's aboutclimbing hydrangeasbut the Hydrangea petiolaris but which have different sizes and morphology (flowers and leaves are different). The appellation ofclimbing hydrangeait is attributed to both species (or in the Chinese case, both to the species and to its subspecies!). On this page we will show you someimagesto clarify the differences between the twoclimbing hydrangeas.
The first photo above shows the still immature inflorescence of the Hydrangea anomala. In the image below, however, a mature inflorescence of theclimbing hydrangeaHydrangea petiolaris.
Climbing hydrangea Hydrangea petiolaris
L'climbing hydrangea Hydrangea petiolarisit is a woody climbing plant, very vigorous and capable of covering surrounding walls, tree trunks or growing on a pergola just like a vine would. It can grow from 9 to 20 meters in height by expanding up to 2 meters in width.
The leaves are deciduous (meaning they fall in the middle of autumn), ovate and flowering occurs in mid-summer. The inflorescences have a diameter of 15 - 25 cm with small peripheral white flowers (sterile) with a diameter of 2.5 - 4.5 cm. The flowers frame very small and very numerous central fertile flowers. Fertile flowers are a couple of millimeters in diameter. From the flowers develop some small fruits of about 5 mm.
Climbing hydrangea Hydrangea anomala
This species is native to the Hymalaya woods and southern China. Again we are talking about oneclimbing hydrangea: it can reach 12 m in height and like the species described above it can thrive on tree trunks, rocks, surrounding walls ... Again this is not aevergreen hydrangeabut of a stripping plant that loses its leaves during the autumn. The oval leaves are 4 to 10 cm long. The flowers have a diameter ranging from 5 to 15 cm in diameter, flowering is summer. The inflorescence has a limited number of larger external flowers and very small central flowers.
Climbing hydrangea, cultivation
Bothhydrangeasclimbing plantsthey have the same cultural needs. The climate should be temperate and tend to be cool, indeed, theclimbing hydrangeayou cancultivateeven in the north of Italy where temperatures drop by several degrees below zero.
Unlike thehydrangeacommon, which prefers a shady position, theclimbing hydrangeawants a sunny or partial shade position. In Southern Italy it should be grown in full shade.
For thecultivationa medium-textured soil of good fertility should be chosen.
L'climbing hydrangeais a rustic plant and for itscultivationno special care is required. Watering should be frequent only when it comes to onecultivation of climbing hydrangea in pots, plants grown in the ground need occasional irrigation. In the open ground, the plant is watered 1-2 times a week. In winter, however, irrigation will be completely suspended.
L'climbing hydrangea in pot, in addition to irrigation, it needs periodic fertilizations. To obtain a good flowering it can be fertilized with liquid fertilizer based on phosphorus and potassium. For potted plants fertilizer is administered from March to September. Therepottingit can be done once every three to four years.
For plants in the ground, it can be fertilized twice a year, adding organic fertilizer as well-mature manure to be planted directly at the foot of the plant. Alternatively, slow release fertilizer can be added.
