That's very cool! Reminds me of some of the guerilla
gardening I have seen and researched. Broadly, it is simply
gardening on
land you do not have the right to cultivate. Sprinkling some
native flower seeds in flower beds, grafting fruiting tissues onto ornamental fruit
trees, and stuff of the like. Perhaps this was the work of one of those individuals?
Either way, I love seeing edible plants used for their ornamental capacities as well, and frankly, I think all ornamental plants
should have a practical use for the homestead. Not that beauty is not worth
enough alone, but that beauty rarely occurs alone and is enhanced by practicality.
All the best,
Eric S.
