OMG! I absolutely love this!! Who sells the seed and do you have the name?
EDIT: DUH, I just needed to click on it. Here is an excerpt for anyone else interested in cultivar…
“First thing worth noting is cultivar. I have only tried this with Blackjack but the important thing is that the plant naturally grows only one main stem. If it splits off into multiple you will have better success with a trellis.
The next important note is moisture. Exposing the soil like this allows the top to dry too fast. In all of my attempts I suffered badly with blossom rot until mulch was added and moisture stabilises. As we are lifting the canopy you must shade the soil one way or another. Next year I’ll be trying with cover crops.”
