Propagating Native Wildlife Trees: Gambel Oak, Chokecherry, and Wild Plum

Cold Stratification Requirements for High-Elevation Native Species

At 8,100 feet in Colorado, fall planting leverages natural winter stratification for these wildlife-value species.

Species-Specific Chilling Requirements

• Gambel Oak (Quercus gambelii): 2-4 weeks at 40°F or below
• Chokecherry (Prunus virginiana): 120-160 days at 36-41°F
• Wild Plum (Prunus americana): Up to 6 months at 40°F or below; naturally low germination; may require two cold/warm cycles

Recommended Protocol

Plant seeds 1 inch deep in flats of quality potting soil in fall. Ensure consistent moisture throughout winter. Seedlings emerge after the last frost the following spring. Expect erratic germination over multiple seasons—especially for wild plum.

Wildlife Benefits

These native species provide critical food and habitat for birds and mammals. Gambel oak acorns, chokecherry fruits, and wild plum drupes support diverse wildlife populations throughout the year.
