Flowering houseplant begonias should be located in a bright spot and receive some direct sunlight.
The main rule of thumb for watering begonias is to not let the soil dry out completely. Stick your finger into the soil, and if it dry to your first knuckle, it's time to water. Avoid overwatering, which will cause the foliage to turn yellow and eventually drop.
All our plants come in a standard plastic container (decorative planters and pots are not included)
