Hi,
thanks for the comments.
Kris, the Kentucky pink looks like Philipp.
Last two for this year.
The reginae also enjoyed last summer.
Much bigger this year with some stems with two flowers.
The plant is now much taller (about 2 feet) and has stems with 7 leaves,
other species/hybrids tend to have 3-5 leaves.
Kentuckiense has also doubled in size. Also with one stem with two flowers.
It really is a spectacular species but nowhere near as tall as reginae.
This clone is nearer 15 inches high.
Regards,
David
