Front two rows -
Luffa aegyptica (they like warm temps, not just no more frost) - useful cucurbits.
Second two rows - Artichoke,
Cynara cardunculus - healthy food, nutrient accumulator, spike root.
Third two rows - Stinging Nettles,
Urtica dioica - healthy food (cooked), nutraceutical, nutrient accumulator, insectary. If you get up close, you can see the formidable nettle spikes!
