Winter savory is the perennial half of the savory family, a low, woody-based plant with a sharper, more resinous flavor than annual summer savory. The trade for that stronger flavor is a plant that survives winter outdoors in zones 4-8, coming back on its own rather than needing to be sown fresh every spring.
How winter savory fits zone 4's season
Zone 4b's frost-free window runs about 128 days, from May 15 to September 20. Winter savory needs about 90 days from transplant to first harvest.
