snow crown cauliflower

Asked June 18, 2015, 3:37 PM EDT


I just cut a head of cauliflower and the stems of the florets have a purple color to them.

This is the first time I have tried to grow this type of plant in my home garden. I was wondering is this head of cauliflower ok to use and if not what did I do wrong?

Thank You

Hello Glenn, and thanks for using the Ask an Expert System,

Cauliflower is a cool weather crop which doe best in lower temperatures of spring and fall. Cauliflower naturally has a range of colors, including purple, red, or blue tints. This is caused by a naturally occurring pigment which is stimulated by warm temperatures and sunlight. The pigment is harmless, but in large quantities it may impart a bitter taste.
