Pinus clausa

A Florida-native, drought-tolerant evergreen conifer with two varieties differing in cone serotiny (persistent vs. open after maturation), regenerating mainly from seeds released from serotinous cones after severe crown fires and maintained by infrequent, high-severity fire regimes, adapted to dry sandy soils and full sun.

Summary

Sand Pine is an evergreen conifer native to Florida and adjacent Alabama, forming scrub forest canopies on xeric, well‑drained acidic sands. It typically reaches 25–40 ft tall with a 12–25 ft spread, has a dense, rounded to irregular crown, and fine-textured foliage with fragrant needles 2–4 in long arranged in pairs; cones are 1–3 in long, spiny and persistent. Two geographic varieties occur: var. clausa (Ocala sand pine) with serotinous cones and var. immuginata (Choctawhatchee sand pine) with nonserotinous cones; seeds are wind-dispersed and regeneration is fire-adapted, relying on crown-stored seeds after infrequent high-severity fires.

In cultivation, plant in open, sunny, well-drained soils; drought- and salt-tolerant once established and suitable for dry landscapes; hardiness zones 8–10; management often involves prescribed fire to mimic natural regimes, as cones open to release seeds after fire. Uses include woodland plantings, specimen trees, highway medians, reclamation, and Christmas trees (especially Choctawhatchee), with seeds providing wildlife forage and habitat for various species; the species is a relatively slow-growing, evergreen tree valued for its fine texture and resilience in sand-dominated sites.
