Torreya de Floride
Torreya taxifolia
L'un des conifères les plus gravement menacés d'extinction au monde : un arbre persistant, pyramidal et à croissance lente, aux aiguilles raides, pointues et vert foncé dont le feuillage froissé dégage une odeur âcre qui lui a valu le nom de « cèdre puant » (« stinking cedar »). Torreya taxifolia n'est indigène que d'un petit secteur de falaises et de ravins frais et ombragés le long de la rivière Apalachicola, dans le panhandle de Floride et la Géorgie adjacente, où une maladie fongique (à laquelle s'ajoutent des changements historiques d'usage des terres et du régime des feux) a fait s'effondrer la population sauvage jusqu'à ne plus laisser qu'un petit reliquat qui, le plus souvent, rejette de souche mais atteint rarement la maturité. En culture, c'est tout au plus un sujet de 30-50 feet, tolérant à l'ombre quand il est jeune et exigeant des conditions fraîches, humides et bien drainées, semblables à celles d'un ravin. C'est une plante de collection à vocation de conservation et une curiosité botanique, et NON un arbre d'ornement courant ; ce qui compte ici, c'est de disposer de matériel d'origine éthique, multiplié en pépinière et issu de programmes de conservation, et un effort actif de migration assistée (les « Torreya Guardians ») l'a, de façon controversée, plantée bien au nord de son aire naturelle.

Elle n'est cultivée que comme plante de collection à vocation de conservation et comme sujet ; les graines et le feuillage ne se consomment pas et ce n'est pas une plante alimentaire.
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.

Well-suited
2050
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.
