Viola volcanica Gillies ex Hook. & Arn.
Viola exilis, Viola volcanica var. volcanica, Viola vulcanica
Viola volcanica is a small, stemless, annual or short-lived perennial that forms stunning dome-shaped rosettes of beautifully textured leaves. The rosettes are up to 2 inches (5 cm) tall and up to 3.6 inches (9 cm) in diameter. Leaves are semi-succulent, in shades of brown, with hairy and scalloped margins. Flowers are small, about 0.6 inches (1.5 cm) in diameter, with five petals, white with violet veins, and a yellow throat. They appear in late spring and early summer.
How to Grow and Care
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 volcanica can tolerate 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.
Toxicity: Violas are nontoxic for humans and pets. Both the flowers and leaves are edible fresh, cooked, or dried.
