The first place to start to find a list of potential plants is our Native Plant Database. Use the Combination Search feature instead of Recommended Species. This will provide a bigger selection with much more choice to narrow down. The volunteers and staff at the Wildflower Center who maintain the database have partners in different regions to help with these recommended species lists based on what is easy to access in local nurseries.
Under Combination Search, select the following categories: New York, Habit – Shrub , Vine or Tree, Duration – Perennial, Light Requirement – Sun, Leaf Retention - Evergreen. This will give you 5 plants to consider. Next you can narrow down your search further by size, flower color, and soil moisture (dry, moist or wet) requirements.
Evergreen shrubs to consider in the 6-12 foot range:
Taxus canadensis (Canada yew)
Evergreen trees to consider in the 12-26 foot range:
Ilex opaca (American holly) Perhaps too wide for the site?
Pinus virginiana (Virginia pine) Perhaps too wide at maturity for your site?
Evergreen vine in the 12-20 foot range:
Lonicera sempervirens (coral honeysuckle)
