*Varieties resistant to witch’s broom only.

**Considered invasive in certain areas. Always check with local authorities before planting.

Shrubs to Avoid

The following shrubs are often offered as hedge plants, but actually make poor choices in most cases:

  1. Honeysuckle (Lonicera spp.): Avoid varieties subject to witch’s broom.
  2. Siberian elm, also called Chinese elm (Ulmus pumila): Popularly sold as a “fast-growing hedge”, Siberian elm is actually a tree and will quickly outgrow its role. It soon loses its lower branches and is highly subject to diseases when heavily pruned.
  3. Spruce (Picea spp.): Their tendency to thin out at the base and to react badly to harsh pruning make them poor hedge specimens.
  4. Yew (Taxus spp.): They make excellent hedges in zone 6 and above, but are subject to winter burn in colder climates.

    you have honeysuckle listed for best and worst. which is it?

    • I’m sorry if the text wasn’t clear. Honeysuckles that are subject to witches brooms make terrible hedges. Onces that are not make great hedges.
