I have two varieties of kale and want to save seeds from both of them.
One has smooth, tender green leaves, the tenderest kale I have ever grown.
The other is a deep purple frilly kale, rich in anthocyanins and vitamin K.
To stop the from cross pollinating I cut the developing flowers off the green kale
and let the bees do their work on the purple kale. When the flowers were falling
off I bagged two sections of the purple kale so they would be completely isolated
from pollinating insects and let the green kale flower.
The seeds from the purple kale bags will be pure and the rest could possibly be
a new variety of tender leaf purple kale.
