One of the most popular houseplants that has animated the minds of many avid plant collectors, the Polka Dot Begonia is one of those indoor plants that everyone seems to need.
Water: Water thoroughly when the top 2-3cm of soil has dried out. Be very careful not to waterlog the soil (check for good drainage) as Begonia's are especially susceptible to root rot.
Light: Ideally some soft direct sunlight for part of the day, e.g. in the morning. Careful to prevent leaf scorching from intense sunlight.
