Interesting. I wonder if there is a difference in the T erectums in cultivation based on their geographical origin. Perhaps the southern ones (say from North Carolina) are better adapted to warm weather than the northern ones. The ones I grow came from western Massachusetts where the average winter lows are around -20F/-30C. --Roy On 4/12/2020 6:22 PM, Peter Taggart wrote: > I have a stem of Trillium erectum flowering now, in a very mild location in > the west of Scotland.
