Hello, I grow several variegated cultivars of tuberosa, but have never tried wintering them. I am trying Manfreda maculosa outside this winter. M.virginica has begun to seed around after three good years in the garden. My original plants from Don Jacobs slowly dwindled away. I assume that the origin of those was southern and they lacked cold tolerance. The current ones are from an unknown Missouri location and a known one near St.Louis. Speaking of Polianthes hybrids, does anyone have access to the Polianthes papers from ISHS/Acta Horticulturae? They have two papers; one on dwarfs, and the other just hybrids in general. Or access to Verhoeks dissertation? Verhoek's hybrids, like many botanical/hoticultural studies, were limited to the study and most likely later destroyed, or left to fade away. I assume a few were given to interested people. You would think by now that they would be fairly "widespread" in the collectors circles if they made it out.
