Zamioculcas zamiifolia, Zanzibar Gem or ZZ Plant.
Apart from
"why is my lemon tree sick", I'm often asked "why is my indoor plant struggling?".
Nine times out of ten the problem will be with either too much or too little water. Well, a Zanzibar Gem will thrive on neglect, only needing water every 2-3 weeks, perfect someone new to indoor plants.
The one above in my bathroom went 4-weeks between watering. Can't ask for more than that!
