I am surprised at tales of rabbits eating the rhizomes.... we have rabbits here, too, but they seem to prefer to go after other things (grass, newly planted loropetalums and carpet roses
, certain annuals). And although we have suffered through the drought, I am guessing there must have still been enough tasty tidbits in the neighborhood, as the deer and rabbits left the irises unscathed.
I forgot to mention, though.... gophers.... Gophers WILL eat your rhizomes.
And if you have raccoons, while they won't eat your rhizomes, they WILL dig them up and scatter them, in pursuit of grubs and worms.
Rosie, thanks for the mention of that
Euphorbia... I'll have to check into it. It looks like something good for the Moon Garden.
