Doublefile Viburnum

Viburnum plicatum 'Popcorn'

The Story

Plant Bio

Doublefile Viburnum is a spectacular deciduous shrub known for its distinctive, tiered horizontal branching. In spring, it produces abundant flowers along the tops of its branches, creating a layered, snow-covered effect.

'Popcorn' is a more compact cultivar that is completely covered in 2-3 inch, ball-shaped clusters of sterile white flowers, resembling fluffy popcorn. It is exceptionally floriferous and develops an attractive reddish-purple fall color.

Uses & Benefits:

Ornamental UsesViburnum 'Popcorn' is a true showstopper in the spring garden. Its elegant, tiered branches are laden with pure white, snowball-like flower clusters, creating an unforgettable display. The deeply veined, dark green leaves turn a beautiful reddish-purple in the fall, extending its season of interest.
Practical UsesThis shrub's manageable size makes it a perfect specimen for small to medium-sized gardens. It can be used as a stunning, unpruned hedge or as a focal point in a mixed shrub or perennial border. The flowers are also excellent for cutting.
Ecological BenefitsWhile the 'Popcorn' flowers are sterile and do not produce fruit for birds, they are still visited by pollinators. The dense, layered branching structure provides excellent cover and potential nesting sites for songbirds.

Planting

How to Grow

  1. Choose a site with full sun to part shade and well-drained soil.
  2. Dig a hole that is twice as wide as the root ball.
  3. Set the plant in the hole so the top of the root ball is level with the ground.
  4. Backfill with soil, firming it gently around the roots.
  5. Water deeply after planting to settle the soil.
  6. Apply a layer of organic mulch around the base.

Pro Tip

Give it plenty of space to develop its beautiful, natural tiered shape. Avoid shearing, which will destroy its graceful habit.
