Sue, Lamb's Ears was one of my moms favorite plants. She loved the feel of their soft fussy leaves. I have not seen the Stachys coccinea 'Pow Wow' before. I will have to give that one a try. The blooms are such a beautiful color. And then to have a fun scent, the grand children would love that one.
I've seen melianthus before, but didn't know it had a peanut butter smell. What are the growing requirements for that plant?
