Florida torreya
Torreya taxifolia
One of the most critically endangered conifers in the world: a slow-growing, pyramidal evergreen with stiff, sharp, dark-green needles whose crushed foliage gives off a pungent smell that earned it the name 'stinking cedar.' Torreya taxifolia is native only to a tiny stretch of cool, shaded bluffs and ravines along the Apalachicola River in the Florida panhandle and adjacent Georgia, where a fungal disease (alongside historic land-use and fire changes) collapsed the wild population to a small remnant that mostly resprouts from the base but rarely reaches maturity. In cultivation it is a 30-50 foot specimen at most, shade-tolerant when young and wanting cool, moist, well-drained ravine-like conditions. This is a conservation-collection plant and a botanical curiosity, NOT a mainstream landscape tree; ethically sourced, nursery-propagated, conservation-program material is what matters here, and an active assisted-migration effort (the 'Torreya Guardians') has controversially planted it well north of its native range.

Cold hardiness
Future
These values are location-based: this location's current hardiness is the baseline, and the 2050 value is a projected future climate for this same location.

Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Well-suited
In plain terms: This location is in Zone 6b today. Its hardiness profile is cold winters, and coldest nights are typically around -3°F. By 2050, the projected hardiness zone is Zone 7a based on SSP3-7.0 (regional rivalry). That is a +0.5-zone shift from Zone 6b to Zone 7a by 2050.
✓
Well-suited today and still thriving in 2050.
Heat tolerance
Future
Heat tolerance values are location-based too: heat days today are observed at this site, and the 2050 value projects this same location under a future climate.
