We kept a Ragged Jack Kale plant going all winter in the hoop house.  After uncovering it and leaving it untended for about three weeks while traveling, we returned to find it looking like this.

I’ve never seen anything like this.  It somehow grew seed pods even though it flowers and spreads itself that way.  The other gardeners in our community garden were equally shocked.

Anyone ever seen something like this happen to a brassica?
