I ordered my callaloo seeds on Ebay 6 or 7 yrs. ago. I had way too many plants for us to eat so some of the plants went to seed. Now they pop up all over my garden and I just transplant them to the area I want them. We've had a crazy spring here in Michigan so my callaloo is just now coming up but it grows fast and I'll probably be cooking it in a week or 2.
I use a Butternut squash for my pumpkin soup along with the cock soup. It's my husband's favorite.
