Chicorée
Cichorium intybus
Une vivace robuste à racine profonde de la famille des marguerites (Asteraceae), cultivée à la fois pour ses fleurs bleu ciel d'été et pour ses nombreux usages comestibles. Originaire d'Europe et aujourd'hui largement naturalisée le long des bords de route et dans les champs à travers l'Amérique du Nord, la chicorée dresse des tiges fines et ramifiées de 3-4 feet de haut à partir d'une longue et robuste racine pivotante. Les fleurs ligulées sont d'un bleu ciel net (parfois blanches ou roses), s'ouvrant le matin et se refermant vers midi. La même plante donne trois récoltes classiques : de jeunes feuilles amères pour la cuisine et les salades, une racine pivotante torréfiée utilisée comme substitut de café sans caféine ou additif, et des pousses forcées et blanchies appelées 'chicons' (endive belge / witloof). Elle prospère sur un terrain pauvre, sec et ensoleillé où les plantes choyées échoueraient, et sa racine pivotante profonde la rend véritablement tolérante à la sécheresse une fois établie.

Les faces bleues ouvertes des fleurs sont travaillées avec constance par les abeilles domestiques et de petites abeilles indigènes pendant les heures du matin, avant que les fleurs ne se referment vers midi, ce qui fait d'un massif de chicorée une source fiable de nectar et de pollen en début de journée.

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.
