I'd say up in the Smokeys there is some Kalmia big enough for spoons, but I have not seen one - unless a tiny spoon. Rhodo - yes. I've tried growing it in my yard, but I surmise it is too hot and not enough drainage here in the Bachelorette Party Nation for it to survive. Same with Big Leaf Rhodos, but I have one now, that seems to be doing ok. Well, also the same with deciduous (flame type) azaleas - luv'em, but can't grow'em! They hang on for a year or two and bang - they are gone. My grandma loved TX Mt Laurel and probably even more so - Purple Sage. She had a bunch of both planted on their property. But none of her's grew big enough for spoons or any bigger than a toothpick or harry potter wand.
