When picking herb plants consider whether they are annual
(1 year life), biennial (2/3 year lifecycle), or perennial (last multiple seasons).
Whether your perennial plants will survive the winter depends
on their tollerance to cold. The seller will tell you to what zone the plant is hardy. You can find the zone you
live in from sites such as Home Depot, gardening books or asking your local nurery. For example, my part of New Jersey
is 6A.
