Espalier Fruit Trees for our orchard. Espalier = the horticultural and ancient agricultural practice of controlling woody plant growth originally for the production of fruit,by pruning and tying branches to a frame so that they grow into a flat plane, frequently in formal patterns, against a structure such as a wall, fence, or trellis.
Manihot grahamii / Hardy Tapioca / Graham's Cassava: a native of Eastern South America, from Brazil through to Argentina. I've done a quick web search and this has been successfully grown as far north as North Carolina. (This photo said it was taken in the Pacific NW).
