Calendula is often used as a substitute for saffron and in Morrocan dishes. See Couscous . 'Pacific Giants' is sold by many seed companies, but it is not marketed as an herb. We have had excellent results with 'Erfurter Orangefarbige' sold by Johnny's Seeds and listed in their herb section. This cultivar is very productive and extremely hardy in Zone 4, making it an excellent choice for landscaping as well. We plant it in spring. If summer comes quickly, it will almost hibernate until fall. It, and Verbena, are often the only plants left blooming after the first few frosts.
