Somehow (priorities, I suppose), I have become a person who can't keep a houseplant alive for anything. Seriously, I have killed a spider plant, and they are notoriously tolerant of neglect. Luckily, my husband has stepped up on the indoor growing, with herbs, lettuces, even tomatoes (supplementing south-facing windows with a full-spectrum LED light)
