Viola cotyledon Ging.
Viola cotyledon is a beautiful perennial plant that forms rosettes of ovate green semi-succulent leaves with white cartilaginous margins. It belongs to the group of Rosulate Violas. Flowers appear in early summer and stand in a ring around the outer edge of the rosette. They vary in color from pure white to dark blue.
The specific epithet "cotyledon" derives from the Greek word "kotylēdōn," meaning "cup-shaped hollow or embryonic leaf in seed-bearing plants" and probably refers to the shape of the rosettes.
How to Grow and Care for Viola cotyledon
Rosulate Violas have a reputation for being difficult to keep alive. Therefore, cold conditions, soil containing adequate nutrients, and as much light as possible are essential.
Soil: They grow in relatively bare loose soils, often volcanic in origin.
Hardiness: Viola cotyledon can withstand temperatures as low as 0 to 50 °F (-17.8 to 10 °C), USDA hardiness zones 7a to 11b.
Propagation: Rosulate Violas are grown only from seed and with some patience.
The main problem with these plants is etiolation, caused by a lack of light, resulting in the elongation of the compact rosettes. However, it is known that in any bunch of seedlings, some of them will quickly etiolate, while others may not. So there is some scope in selecting Rosulate Violas more likely to grow satisfactorily in cultivation.
