I never had any luck growing this plant outside in PA. They always died in the summer. They where potted in glazed pots and I never tried any terracotta pots.
I tried again growing this plant inside in an orchid pot in a south facing windowsill where I've had success with it.
Don't laugh, but a plant sent to me from the West Coast not only survived for me, it did so outside, from spring through fall. I had it wintered in a co-worker's garage and last spring it flowered. I went on to produce a stolon and is again being wintered in the co-worker's garage. I hope to bring it and the rest of the temperates back in a few weeks. We may not be as warm as Red Lion, but we had a few days in the 90's last summer.
