What are the pros? Potential for perennial kale
What are the cons? Challenging germination
I took half of my seeds and put them in the fridge with moist peat. I saved the other half anticipating poor germination. After a week or so more than the required amount of cold stratification, I placed the seeds in a window greenhouse. Nothing ever sprouted. With the second half of my seeds I put them directly into the window greenhouse. Still no sprouts, so I put themin the fridge after the warmth. Then I placed them back in the window after I noticed two sprouts while in the cold stratification. Those sprouts were too leggy, but 4 more popped up shortly after.
I did not have luck protecting them once planted in the garden. I think some cabbage caterpillars chomped at them and some neglect led to their demise.
I do not recommend this plant if you are trying a lot of other new plants in the same growing season.
