Janice H. asked Annie:
Q Should yellow-flowered violets be grown cool or warm to get true yellow? I have 2 violets with yellow blooms: Senk’s Alchemy Morning Star and Ajohn’s Winter Sun. Ajohn’s Winter Sun is now blooming, but the flowers are a very pale yellow. Do they get more yellow as the plant gets older? This is the first bloom for this plant.
A Hi Janice. Generally speaking, cooler temps make for more vivid colors, so I would say that cooler temps might help deepen the yellow blossoms. As to whether the color deepens as the plant matures – I cannot answer that one. I have not grown anything with yellow in it in quite some time, but I would give the plants a few more bloom cycles to see if changing temperature has any effect.
