Why not grow some edibles as houseplants? My houseplants include two dwarf lemon trees, pineapple sage,
lemongrass, and a bay tree. Tropicals that will not survive outdoors year round in your climate may make great houseplants.
I move mine outdoors for the summer and back inside before the
temperatures drop below 45 F.
