Chickasaw Plum (Prunus angustifolia) · Species Notes

Restoration Role

Thicket-forming wildlife shrub/small tree. Chickasaw Plum builds dense low cover for nesting birds and small game, offers early pollinator bloom, and fruits heavily. It naturally forms colonies that anchor woodland edges and shelterbelt understory.

Site Suitability

PrimaryShelterbelt and woodland edges

SecondaryDrainage Savanna Corridor, Filter Band margins

AvoidWet drainage core, standing water

SoilsSeC, SuB, RuB — it prefers loose sandy ground and tolerates lime, so expect looser colonies on our heavier clay

HydrologyDry to moderate; well-drained

RangeIn range: NPSOT lists it for the Cross Timbers, including the Carbonate Cross Timbers and Grand Prairie next door; the Cut Plain is its southern edge.

Propagation & Care

Seed collectionCollect ripe plums early summer. Pulp must be cleaned promptly.

StratificationClean seed and cold-moist stratify 60–120 days. Suckering is faster and truer than seed.

PropagationPreferred: lift dormant root suckers from a donor thicket in winter and pot up. From seed: sow after stratification, expect uneven germination.

Container progressionSucker / seed → 5-inch pot → 1-gal fabric if needed → Field planting in clusters to establish a thicket.

Nursery wateringModerate while establishing; tolerant once rooted. Fabric stage: if the plant moves up from the 5-inch pot, fabric dries much faster than plastic and needs a lot more watering outdoors in a Central Texas summer. We have not set the frequency yet.

LightFull sun for best fruiting and density.

OutplantingBest age 6–12 months. Plant November–February. Stock held in a 1-gal fabric pot can go out later — air-pruned roots don’t circle, so the window extends. The first cohort will set the actual figure.

Establishment Watering

Year 1: 5 gallons every 2 weeks during drought.
Year 2: drought only.

Field notesPlant in groups and let it colonize. A Chickasaw Plum thicket is one of the highest-value habitat features we can build quickly.
