Begonia Maculata or commonly known as Polka Dot Begonias, it’s the new plant on the block. Give him a weekly watering and a light spot and he will provide you with lots of new growth.
Needs watering once a week and thoroughly water the soil but always let it drain out. Don’t let it stand in water in the ceramic as it is susceptible to root rot. A nice indirectly sunny spot would work. Window sill but not too much full sun. These can grow quite tall so be sure to stake if the stems need a bit of support!
