1999 Vermont Flower Show

Woody Plant List

Many of the following trees and shrubs may be found at the 1999 Vermont Flower Show. Due to design and forcing considerations, however, not all may be present, and there even may be a few additional plants! Hopefully this list will serve as a useful reference, and introduce you to some new and choice plants for Vermont gardens. Zones refers to the USDA hardiness zones, with most of Vermont being zone 4, the colder parts zone 3.


Arborvitae, Hetz Midget (Thuja occidentalis ‘Hetz Midget’)- Best described as a small green ball, this arborvitae is very slow growing. It was selected in the 1930’s by Fairview Nursery in Fairview, PA. Zones 2-7.

Birch, Paper or Canoe (Betula papyrifera)- The cool thing about paper birch is that it retains its best ornamental quality all year (although the white bark does tend to blend in a bit in the winter). It does have other qualities as well, like yellow fall foliage and decorative catkins (the fruit). Native to North America. Introduced in 1750. Zones 2-7.

Zones 4-9.

Rhododendron, Molly Fordham (Rhododendron ‘Molly Fordham’)- A small to medium sized (5-10ft) shrub. ‘Molly Fordham’ has many great qualities, the two most important being early bloom time and exceptional hardiness. Zones 4-7.

Spiraea, Goldflame (Spiraea x bumalda ‘Goldflame’)- Vivid and changing leaf color earned this plant its popular status.

Spiraea, Gold Mound (Spiraea japonica ‘Gold Mound’)- Similar to ‘Goldflame’ Spiraea, but leaves stay at the yellow-green stage all summer. 2-3’ x 3-4’. Zones 4-8.
