Try freezing chunks for hot time treats...more likely to take a few bites. I run pea hulls thru my food processor and freeze them in zip bags with water...birds love them.Animals can be funny that way! I had some goats that refused to eat apples! But once they saw the other goats eating the apples, they wanted their share! Keep trying, they may decide they like things they reject at first.
Shiso is a Japanese herb and ornamental, leaves green on top, purple underneath. A member of the mint family, with a robust herbal flavor and a hint of licorice. Great in small doses in a salad, or to wrap sushi. Also easy to germinate and grow, tho has been a little sulky in this heat. I think it would be considered a tender perennial in KY.
We have that in our garden too....folks here call it purple basil. It spreads by seed so prolifically that I have to thin it out like crazy.
