Curator: Nate Sands
The planting for this collection began in Fall of 2007. The purpose of the collection is to illustrate the wide variety of conifers that exist. Conifers in the collection show the varying habits, characteristics, and colors that make conifers a fascinating group of plants and also a vital part of the landscape. Many of the conifers in the garden will be registered names and are available to the trade, but some have not been registered and introduced to the trade.
Conifers are commonly classified as follows:
• Miniature – 1” or less of growth per year
• Dwarf – 1-6” of growth per year
• Semi-Dwarf or Intermediate – 6-12” of growth per year
• Large – more than 12” of growth per year
• Globose: globe-like or rounded in general outline.
• Pendulous: upright or mounding with varying degrees of weeping branches.
• Narrow upright: much taller than broad; includes plants referred to as fastigiate, columnar, narrowly pyramidal or narrowly conical.
• Broad upright: includes all other upright plants with do not fit into categories 1-3.
• Prostrate: ground-hugging, carpeting plants without an inclination to grow upward.
• Spreading: wider than tall.
• Irregular: erratic growth pattern.
• Culturally altered: pruned or trained into formal or imaginative shapes, such as high grafts or standards.
