What a great thing you guys are doing! I think the different types of things are great to try growing @ home! A package of seeds is wayyyyy cheaper than trying to find & PAY for the unusual! My CSA always has rainbow carrots in the fall, one thing, the purple ones are only colored on the outer part, the core is still orange. Something really pretty are striped beets, look like candy canes & are yummy sliced (so you see the stripes best)& tossed & roasted w garlic, lemon juice, zest & olive oil. The time you spend w/your kids doing stuff like this is like seeds...the thoughts, habits & feelings are planted & you & will reap the rewards for the rest of your lives, possibly the lives of your grandchildren! I'm secretly looking forward to having grandchildren. Crazy bee & cat Grammy Jo...or maybe Nannie, like my Grandmother. She is where I got the love of gardening. I so miss having young children, running the daycare was the hardest & most rewarding job I have ever done, well, besides raising my own girls! Tell your son that those are some really beautiful plants he has going there! Keep the pictures coming so we can watch the progress! J
