US hardiness zone 7 is large and stretches over 28 states in total. It spans from Cape Cod, MA and covers parts of Virginia, North Carolina, and Texas before traversing up the western side of the Rockies. In February it is too cold for most of the region to sow seeds outdoors, but the month offers a great opportunity to sow vegetables, herbs, and flowers indoors.
The typical last frost day in spring for the zone can be around the end of March or the first weeks of April. There are lower regions with warmer temperatures and colder altitudes within the zone and any particular location within zone 7 will affect the exact best timings for sowings.
