I think everyone should have a houseplant. If you say you can't take care of them or they always die...that's no excuse. Start with something easy... a hearty fern or a cactus.
Not only are these little plants a bit of spring in December and a low-budget way to commune with nature but they also provide numerous other benefits:
A) they give you practice should you be considering your first pet. Weekly waterings get overwhelming? Fail. No puppy for you!
B) they purify the air...kinda... unless you've got a veritable forest of violets, mini palms and lilies one person will probably produce more C02 than that one leafy purifier can filter... BUT you are going to feel great when you breath deeply near its recently-watered soil!
C) a friendly reminder of just how habitable your home is. Consider... if you don't have good enough tap water quality, regular amounts of sunlight and a tidy counter top somewhere... should ANYTHING really have to live like that?
D) built in audience of unwavering, unconditional solidarity. You'll never eat alone again, never dance in the living room without a crowd and can practices speeches or positive affirmations any time of the night or day.
And in a note of my own personal victory - something for all new plant-owners to look forward to: one day the droopy one will perk up, the stagnant one will double in size and the bland one you never liked will bloom in the most beautiful way...and it'll be all because of your careful attention & very limited effort.
So excuse me while I go do the Houseplant Dance.
