Decumaria barbara |
Climbing Hydrangeas
included in this group are Decumaria barbara, Hydrangea anomola subsp. petiolaris and Schizophrama hydrangeioides. These
are all vines which climb using aerial roots to attach to the outer surface of
walls, rocks, tree trunks or wooden structures like pergolas. Unlike English
Ivy they rarely become a problem on trees. Climbing hydrangeas only bloom on
vertical stems – vines growing on the ground will not bloom. Minimal pruning is
required. They bear lacecap inflorescences with an outer ring of showy white
sterile florets around creamy to yellow fertile flowers in late spring.
Deadheading can be done right after flowering to save energy and for aesthetics
by cutting the inflorescences off above the first leaf. Branches that extend
out far from the climbing surface may also be pruned back in summer after
flowering to prevent the plants from being pulled from their structures by
heavy winds, ice or snow. Climbing hydrangea vines will grow well throughout
Virginia in moist shady sites. In cooler parts of the State they can take more
sun as long as they receive adequate moisture during the summer. after
flowering to prevent the plants from being pulled off by heavy winds, ice or
snow loads.
Decumaria
Decumaria barbara |
Woodvamp (Decumaria) is a genus of two species of flowering plants in the family Hydrangeaceae, one (D. barbara) native to the southeastern United States, and the other (D. sinensis) native to central China.
They are shrubby lianas growing to 4-10 m high through shrubs and trees, climbing by means of aerial adhesive rootlets. The leaves are variably deciduous to evergreen (with D. barbara tending to be more often deciduous, D. sinensis more evergreen), 3-10 cm long, ovate with an acute apex, and a smooth to obscurely toothed margin. The flowers are 5-10 mm diameter, white to creamy colored, fragrant, produced in dense panicles 3-8 cm broad. The fruit is a dry capsule containing several seeds.
