Lavender, much underused as a herb, can be sown by seed in spring. Its flowers can crystallized and used to flavour oil, or vinegar, as well as lavender water, herb pillows and tea. Historically it was used to treat headaches, swooning, and to strengthen the spirit in times of grief. An old wives tail is a woman with lavender planted in her front garden would never marry; so that’s me shot then.
Sage is another underrated herb, seeded in spring, supposedly good for the liver and a cleanser of blood, healing for wounds, ulcers, cramps and colds. It also tastes great in stuffing’s and meat dishes
Rue, a very pungent herb, sown in spring, added sparingly to salads in summers and causes a rash if picked on a sunny day sans gloves. Historically it was as its name suggests and used to provide relief against inflammations.
There’s also alfalfa, but I don’t know its historical connections. It is grown in spring tho.
