We have literally not a single plant in our apartment, and I'm sick of it! We need some green! But I have no idea what to start with.
FWIW we're in the far nordics near the arctic circle, so conditions in places like windows vary quite wildly throughout the year, from occasionaly hot and long summer days to cold and very short winter days.
Not really fuzzed about beautiful flowers, just leaves, vines, will keep us happy. Maybe succulents?
I would recommend spider plants! They are extremely easy to grow and care for, they tolerate many different soil types and moisture levels, and they spread quickly so you can get a whole bunch of baby ones to keep your collection growing. And an added bonus, they are one of the best plants for air purification!
