Grafting Herbaceous Stock
Although grafting is an age-old technique, herbaceous grafting is a fairly recent invention.
This is an excerpt I found years ago while googling cocktail tree. It's the concept of a cocktail herb. Basically take those pomato's (tomato-potato) you see everywhere and multiply it on a larger scale. I.E. Brussel sprouts and kale on one plant, etc...
"Brassica oleraceaseems like a particularly good candidate for such an experiment. This one species includes cabbage, broccoli, cauliflower, Brussels sprouts and kale. Yes, all these plants are cultivars of the exact same species"
Has anyone seen something like this done before, for sale. mentioned by another, etc,..? I'm not going to try making one, but would be interested in buying if their is a source. I can't find much info so all helps.
