  • Culture:

    Adaptable. Tolerates wet sites, and is less tolerant of dry conditions than the other lacecap viburnums (V. sargentii and V. opulus). Full sun to partial shade.

  • Notes:

    White flower clusters are surrounded by a ring of showy sterile flowers (lacecap) in late May-early June. The fruit become a translucent red in fall persisting into spring and are beautiful in the winter landscape. The fruit are tart (hence the common name) and are used for jellies and jams. Fall color is an excellent bright red to maroon.

  • Pollination of viburnums:

    As are most viburnums, this species is self-sterile (cannot pollinate itself) and therefore requires another individual of the same species nearby for pollination and subsequent fruit display. Using clonal plants (cultivars) may be desirable where uniformity is important, but a planting of a single cultivar will bear few fruit.

  • Pruning:Pruning animation

    Renewal pruning is accomplished by removing the largest, oldest stems (generally 1/4 to 1/3 of the total stems) as close to the ground as possible. This will stimulate new shoots to develop below the cuts which will fill in the plant creating a more dense and pleasing habit.

    Renewal pruning should be done when the plant is dormant, late fall to early spring.
