Nice to meet you Karen. As another renter I havent been concerned about the size of the garden, but happy for the chance to play wioth a big variety and watch and learn (or in permaculture parlance: Observe and Interact). It has been a great time to build my knowledge.
A few additional things to your list that you would probably enjoy: Maori potatoes, French Sorrel, Stevia, Chinese Cabbage, Garlic.
Welcome and enjoy finding your way around. There's lot here. If you need help on anything, search first, then ask way - there's a tonne of knowledge in here, and the best online community I know of.
