Having a south facing window or at least some source of sunlight helps. My houseplants are miserable; the backyard is south facing and it's all blocked by tall trees. Makes for a pleasant yard for humans to lounge in even during the heat of the summer, but not ideal for growing much. 3 dogs that'll destroy anything in their wake doesn't exactly open up many options.

I have been at least looking for somewhere more in front/on the sides to put some comfrey in to maybe try my hand at some soaps/salves. Got into making my own tallow a few months ago and it doesn't look like too much of a jump to start using it for things other than food. And if there's a plant I won't likely kill, comfrey seems like it. Though it may need to battle off some japanese knotweed...
