This year I am trying to grow more medieval plants, along with my usual new world favourites. So far I have Cos lettuce growing in flats inside, along with cucumbers. Cos lettuce looks fairly similar to Romaine and is the lettuce believed to be most like the lettuces shown in illuminations such as this, from the Tacuinum Sanitatus:
I have skirrets (a Tudor root vegetable) and Good King Henry (a variety of goosefoot) undergoing cold moist stratification in my refrigerator (germinating on damp paper towel, inside a freezer bag). I am about to plant bayberry (useful for scenting soaps) and lavender in more starter pots. Outside, I have planted more lettuce (saved from my own seed from last year), peas, parsnips, kale, and madder (for use as a dye plant).
The next big jobs will be to rework my front garden so that it is primarily for herbs. My neighbour makes soap so I want to grow lots of things she can use.
