If you haven't already tried growing things, I think it’s worth an attempt. There's something pretty magical about planting a seed and having it turn into a living thing. (I’ve often wondered whether it could be therapeutic for would-be-parents.)

I particularly like growing plants that are edible (bonus points if they're things I can pop in my mouth while gardening, e.g. cherry tomatoes). Plants that totally overproduce like zucchini, or maybe herbs that you can just trim now and again.

But even regrowing my scallions in water glasses on the windowsills for my next batch of

is pretty delightful.

Cut flowers are also nice, especially if you're willing to bring them inside or share them with friends when they hit their peak.
