Tuya del este
Thuja occidentalis
Un árbol de hoja perenne denso, cónico a estrecho-piramidal, nativo del este y centro de Norteamérica, apreciado como conífera para pantallas y plantaciones de fundación. Ramillas planas en forma de abanico con follaje escamoso, aromático y de color verde-amarillento cubren el árbol desde la base, y la corteza marrón-rojiza se exfolia en los troncos maduros. Los árboles silvestres pueden alcanzar 40-60 feet, pero las plantas cultivadas suelen mantenerse cerca de 20-30 feet; los pequeños conos en forma de urna y la densa cubierta perenne lo hacen valioso como alimento y refugio para las aves.

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.

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.
