I couldn't decide which one I liked better. So, I uploaded this work too.
Flower colors vary in the genus, ranging from violet, as their common name suggests, through various shades of blue, yellow, white, and cream, whilst some types are bi colored, often blue and yellow. Many cultivars and hybrids have been bred in a greater spectrum of colors. Flowering is often profuse, and may last for much of the spring and summer.
One quirk of some viola is the elusive scent of their flowers; along with terpenes, a major component of the scent is a ketone compound called ionone, which temporarily desensitizes the receptors of the nose, thus preventing any further scent being detected from the flower until the nerves recover.
