Shrub Viburnum plicatum f. tomentosum [Doublefile Viburnum] The Doublefire Viburnum is fertile and more commonly used in the landscape than the sterile Japanese Snowball Viburnum (Viburnum plicatum f. plicatum). The white flowers are reminiscent of a lace doily with sterile showy flowers at edge surrounding the non-showy fertile flowers. Flower clusters accentuate the horizontal branching. Fruits are red that change to black if not eaten by birds, beginning in late summer.
Shrub Viburnum × 'Pragense' [Prague Viburnum] More drought tolerant than most Viburnums. Topping may be needed initially to encourage branching. This hybrid arose in Prague, Czechoslovakia in the 1950s.
