  • Protect from occasional frost between November 15 and March 15.
  • Some plants need protection when temperatures drop below 40°F.
  • Temperatures are stated for 75% or better germination rates.
** Use heat-tolerant, bolt-resistant varieties for winter and spring planting. These will last even into summer. Use heat-tolerant varieties for late summer and fall planting. A source for heat-tolerant and bolt-resistant seeds: Native Seed Search

† Naturally bolt-resistant.
