Avoine commune
Avena sativa
L'avoine cultivée, une graminée annuelle de saison fraîche, dressée, cultivée pour son grain, comme fourrage et — de plus en plus au jardin — comme engrais vert à croissance rapide qui améliore le sol. À partir d'un semis de printemps ou de fin d'été, elle dresse des chaumes élancés et verticaux de 2 à 4 pieds couronnés d'une inflorescence ouverte et légère (une panicule étalée) dont les épillets pendants mûrissent du vert au doré. Domestiquée dans l'Ancien Monde à partir d'avoines sauvages, ce n'est pas une fleur sauvage indigène mais une véritable culture annuelle : elle germe vite, étouffe les mauvaises herbes, produit de la biomasse et, dans les zones froides, gèle commodément en hiver pour laisser un paillis facile au printemps. Les jardiniers l'utilisent surtout comme engrais vert et culture nourricière qui freine l'érosion, et pour la texture douce et herbeuse et les épis qui mûrissent en doré qu'elle apporte pendant sa croissance.

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.
