Plant Information

  • Scientific Name: Viburnum dentatum 'Ralph Senior' Play audio of plant name
  • Parent: Viburnum dentatum
  • Zone: 3
  • Plant Size: 8-10'
  • Habit: Vase
  • Culture:

    Very adaptable. Tolerates wet sites. Full sun to shade.

  • Notes:

    May be useful where uniformity is important such as in a screening hedge, otherwise seedling-grown plants would be prefered. This cultivar's fall color is at best inconsistent, and usually non-existent.

  • 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.
