Growing Chervil in Wyoming: Complete Guide
Chervil (Anthriscus cerefolium) is a crop that grows best when sown directly in the garden. In Wyoming, the right time to direct sow is around Saturday, March 28, 2026, once soil temperatures are consistently warm enough for germination.
Because Wyoming stretches across 4 USDA hardiness zones (4a, 4b, 5a, 5b), planting windows can shift by as much as two to four weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.
With 50 days to maturity, Chervil fits comfortably within Wyoming's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.
Chervil requires partial shade (3-4 hours) and moderate (1 inch/week) moisture. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
