Thats a real impressive clump Frank,no mistake
If you ever get any more pups sneaking into your yard,I'd be willing to try one over here in the UK.
Can't source a proper intinerans for love nor money here,which is a shame as I'm sure they'd be hardy enough to survive.
My yunnan managed it last winter,but got cut back to the corm by the real cold spell we had.So a proper itinerans var itinerans would breeze it here I'm sure
I'd buy you beer for your troubles
