Pachysandre d'Allegheny
Pachysandra procumbens
Un couvre-sol de sous-bois semi-persistant indigène du sud-est de l'Amérique du Nord (Pachysandra procumbens), apprécié pour son feuillage marbré de vert-bleu à bronze et ses épis floraux parfumés en forme de goupillon, blancs à rosés, qui s'ouvrent au ras du sol de la fin de l'hiver au début du printemps. Contrairement à l'envahissante Pachysandra terminalis asiatique si répandue, cette espèce indigène s'étend lentement par rhizomes en colonies compactes et bien tenues, ce qui en fait un couvre-sol bas et sobre pour les plantations indigènes à l'ombre.

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.
