Viola coronifera W.Becker
Viola coronifera var. minoriflora
Native to Argentina.
Viola coronifera is one of the Violas with leaves arranged in a rosette. It is an attractive perennial plant with solitary or few to several rosettes of green, ovate leaves. The rosettes grow up to 4 inches (10 cm) tall and up to 2 inches (5 cm) in diameter. Flowers appear from late spring to early summer. They are sweet-scented, yellow, or soft orange and form a crown at the top of the rosette, hence its specific epithet "coronifera."
How to Grow and Care for Viola coronifera
Rosulate Violas have a reputation for being difficult to keep alive. Cold conditions, soil that contains adequate amounts of nutrients, and as much light as possible, are essential.
Soil: They grow in relatively bare loose soils, which are often volcanic in origin.
Hardiness: Viola coronifera 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, which results in elongation of the compact rosettes. 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.
