How these dates are built
Sprout applies the cited planting offsets to the typical zone 7a frost anchors. The result is a planning baseline for the zone, not a local weather forecast.
- USDA Plant Hardiness Zone Map, 2023USDA Agricultural Research Service / Oregon State University PRISM Group. Supports the USDA hardiness-zone band.
- U.S. Climate Normals 1991-2020NOAA National Centers for Environmental Information. Supports the median spring and fall freeze dates.
- German Chamomile, Matricaria chamomillaUniversity of Wisconsin-Madison Division of Extension (Wisconsin Horticulture). Supports indoor seed-starting timing (direct) and direct-sowing timing (normalized).
Method note
Annual lifecycle (German chamomile; the Roman type Chamaemelum nobile is the perennial), full-sun requirement, indoor start 6-8 weeks before the average last frost, direct sow shortly before the last frost, surface-sowing (seeds need light, so depth recorded as 0), and the aphid / self-seeding concerns from this page. Both windows are anchored at the last spring frost. No spacing, pH, or water-per-week figure is given (keep upper soil moist but not wet).
