Tracey, there's something about that compost pile that holds the key. I know its wetter and damper there and cooler, too. Lots of leaf compost and chunks of old sod, etc. I'll try and get a pH. But, my gosh, the ones I bought last year won't grow with the rest of my Orientals and OT's or anything in a regular garden. Maybe it likes a more natural environment with all the weeds and grass as company.
