I second this. My wife went through a health scare (she's fine now) early in 2022, during which she was a little depressed. one of her outlets was to go to home goods or lowes and buy house plants - one or two at a time, every week or two. those stores have pretty generous return policies if you kill the plant - homegoods 30 days, lowes - a full year!

I think we have about 25 houseplants now including a couple of large ficus and fan palm trees, she waters them all at once on the weekend and it doesn't take much time at all, maybe 15 to 30 minutes per week; there are some annual maintenance tasks as well like re-potting but the return on time investment is really fantastic. Guests always comment how lovely it is in our living room surrounded by plants, and she has a new hobby of propagating the houseplants and giving new plants as gifts. All in all, I'm sure it's more than $200 in total, but if you find good deals, $200 can probably buy between 5 to 15 very nice houseplants.

Which ones?

Just came back from an exceptionally cold vacation to Iceland and realized that despite years of backpacking and hiking in temperate weather, I knew not nearly enough about layering for truly cold weather.
