Description
Viola columnaris is one of the Rosulate Violas with leaves arranged in a rosette and typical "Heartsease" flowers. It is an attractive perennial plant that spreads using rhizomes. The leaves change color to blend in with their backgrounds, making the rosettes difficult to detect when not in flower. The rosettes can reach up to 3.6 inches (9 cm) in height and 2 inches (5 cm) in diameter.
The flowers are white with violet veins and barely emerge from the rosettes in spring and early summer.

How to Grow and Care for Viola columnaris
Rosulate Violas have a reputation for being difficult to keep alive. 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 columnaris 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 the elongation of the compact rosettes. However, it is known that some seedlings will quickly etiolate in any bunch, while others may not. So, there is some scope in selecting Rosulate Violas that are more likely to grow satisfactorily in cultivation.
