I Found a Woodlanders Hardy Red BottleBrush in Utah! | The Most Cold Hardy Callistemon

While most Callistemon varieties are cold hardy only in USDA Zones 8b, 9, and 10 of Southern California, Arizona, and Southern Utah, ‘Woodlanders Hardy Red’ Bottlebrush is hardy to USDA Zone 7b. Where it has withstood temperatures of 5°F or lower. The older the plant gets, the more cold hardy it becomes. I’ve heard that older plants have survived temperatures below zero. The arching branches of ‘Woodlanders Hardy’ Bottlebrush form an evergreen mound 4 to 5 feet tall, and equally as wide. Bright fire red, fuzzy, bottlebrush flowers appear in late spring and then sporadically through the rest of the warm season on established plants. The long narrow evergreen leaves emerge a beautiful coppery color before maturing to dark blue-green, and have have a fresh, lemony scent when bruised.
