Begonias are a large genus of flower plants that belong to the Begoniaceae family. The plants bear large, attractive flowers in yellow, scarlet, pink and white. According to Mark C. Tebbitt in the book "Begonias: Cultivation, Identification and Natural History," there are more than 1500 different types of Begonias. Every type is slightly toxic, with the roots, tubers and rhizomes being more toxic than other parts. If ingested, these parts cause non-fatal poisoning in animals and humans. Symptoms include swelling and burning of the mouth.
