You have just moved, or you have just decided, and you want the first plant.
Here is what we think.
Buy it in person, not online
A plant survives a van ride better than an overnight freight shipment. Go to a local shop. Look at the underside of a leaf. Touch the soil. Notice whether the plant leans toward the shop's light source.
Start with a Pothos, a Snake, or a ZZ
All three are famous for a reason: they tolerate neglect, irregular light, dry heat, and the weeks when you forget to water. A ZZ plant will thrive on a north wall, in a tiny pot, for years. A Snake plant will forgive a month of drought. A Pothos will grow from a cutting in a glass of water on a bookshelf.
Terracotta, not plastic
A terracotta pot breathes. It absorbs water from the soil and evaporates it slowly, which makes it almost impossible to overwater. A plastic pot seals everything in, and most first-time plant owners kill their first plant by drowning it, not starving it.
A six-inch terracotta pot costs three dollars at any garden center. Buy two.
And then
Once you have kept one plant alive for three months, you will begin to want a second one. Let that happen on its own schedule.
