Conifer Collection

This is a tree or shrub of the order Coniferales. Most conifers bear cones and most are evergreens, though a few, such as the larch, are deciduous. Conifers are widely distributed over the world but are mostly found in the highlands of temperate regions.

This garden shines in July, August and September, when colorful masses of black-eyed Susan, purple coneflower, bee-balm, catmint and flowering sage are further ornamented by flying “flowers” attracted by their nectar and pollen.

Myrtle S. Holden Wildflower Garden

(29 habitats)          

Holden’s Wildflower Gardens display herbaceous wildflowers and woody plants that are native to our region. These are arranged in habitat plantings, in which plants are placed together with those plants that they grow with in the wild.

Helen S. Layer Rhododendron Garden 

This garden encompasses 25 acres of groupings of rhododendrons, azaleas and related plants under a canopy of mature oaks, beeches and maples. While the bulk of flowering occurs in April, May and early June, the sheltering tree canopy makes this area a favorite destination for peaceful walks throughout the summer and fall.
