Because rosemary can be marginally hardy in our area, try planting the especially hardy cultivar 'Arp'. Greek charioteers even fed it to their horses, but for a different reason. They believed it would improve the horses' stamina. Parsley is a biennial, meaning it puts out foliage the first year and flowers the second year before dying. Prune off the flowers if you want to keep it another year.
Parsley grows in full sun and blooms in early summer.
It attracts the larvae of the Swallowtail butterfly and grows 1' high and wide. The Chinese believed it could bestow immortality. And the Egyptians put coriander seeds in their tombs. If you lived during the Renaissance period or the Middle Ages, you might have ingested coriander as part of a love potion. Coriander is an annual that gets about 3' high.
