Avonia is a fascinating family of caudiciform plants. Avionia stay very compact and may have a base that matures at four inches wide by two inches tall. Most Avonias are verysensitive to overwatering. The grower should let the soil become completely dry before watering again. We would consider this family of plants to be reserved for advanced growers. Avonias normally have white flowers but occasionallymay have  pink, which are highly sought after by collectors.
