Œillet d'Inde

Tagetes patula
Une annuelle estivale compacte et rapide originaire du Mexique et du Guatemala (malgré le qualificatif « French » dans le nom anglais), cultivée en massifs, bordures et conteneurs pour sa couleur. Elle atteint généralement 6-12 inches de hauteur avec des fleurs simples à très doubles de 1-2 inch, parfumées, en jaune, orange, rouge et bicolore, sur un feuillage aromatique finement penné et denté. Fleurit de juin jusqu'aux gelées en plein soleil, peu exigeante, et fait partie des rares annuelles que les cervidés ont tendance à laisser tranquilles.

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.
Now
Zone 6b

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.
