Tradescantia zebrina 'Silver Plus'

Another name: Trardescantia zebrina 'Violet Hill',
Common names: Violet Hill, Pink Joy, Silver Sicilian

Probably the most popular cultivar of tradescantia. It is available in many stores and florists. Unfortunately, it is often sold under different names (you can read more about common names <<here>>).
The cultivar 'Silver Plus' is characterized by wide stripes of a silver color on the leaves. With a small amount of light, the leaves are green (similar to 'Discolor'). With a lot of light, green turns into dark purple, while at very high light intensity, 'Silver Plus' becomes burgundy (last photo).
