  • Notes:

    An exceptional ornamental vine. The mid-summer flowers are fragrant, white with a ring of showy sterile florets around the central fertile florets. The glossy dark green leaves remain until late fall when they drop revealing the splendid red-brown exfoliating bark. Small branches grow out from the vine giving a third dimension to a wall. Is very slow to establish, but becomes quit large with age.

  • How vines climb:

    The means by which vines climb can be divided into two broad categories: those that twine around a supporting structure, and those that hold onto structures by use of holdfasts.

    Twining: Twining vines wrap around a support using tendrils, petioles or the stem of the vine. These vines require a support structure that facilitates twining such as a fence, arbor or trellis. When these vines become overgrown they can be renewed by cutting the entire plant back severely in early spring.

    Holdfasts: This group of vines attach using holdfasts or aerial roots, structures that fasten the vine stem by sticking directly to a structure. These vines can affix to almost any surface, but are best used on masonry. They are not recommended on wood structures as they create a moist environment that can lead to rot, and the holdfasts are difficult to remove and may damage the wood
