Dianthus barbatus
Un classique des jardins de cottage appartenant à la famille des caryophyllacées (Caryophyllaceae), originaire des montagnes européennes (Pyrénées, Carpates, Balkans). NC State Extension décrit une plante dense, dressée et arrondie de 1-2 feet de haut et 6-12 inches de large, aux feuilles étroites en forme de lance, vert grisâtre à bleu-vert, et aux inflorescences plates, denses et arrondies de fleurs parfumées, souvent bicolores, dans des teintes allant du blanc au rouge intense et au violet au printemps. Il peut être cultivé en annuelle, bisannuelle ou vivace à courte durée de vie ; cette fiche le traite comme la vivace à courte durée de vie qu'il est dans sa zone USDA 3-9. Les abeilles et les papillons butinent les inflorescences, et la plante est résistante aux cerfs et aux lapins.

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.
