Highly adaptable. While frequently in moist areas, broadly tolerant of dryness. Has been planted extensively for timber. This tree occurs throughout Florida and has both southern and northern varieties with the southern form being more tolerant of fire. Recent research on sea level rise indicates that significant salinity of water in the root zone will eliminate the species.  The area occupied by slash pine in the keys is shrinking. Many places with slash pine plantations were formerly longleaf pine forests.  Many of these sites are too dry for optimal health of slash pine. Shade tree. Forest tree -- this is one of the most highly used species for timber production.

The interesting flower shape reminded early settlers of someone standing in a pulpit. Retain if present. Interesting in a moist shade garden as its flowers form a small preacher in a pulpit.
