Cool... it would be fun to try rooting a cutting.
Regarding the Ilex... here's one of the I. opacas at the Arnold arboretum after this winter:
The only green leaves appear to have been below the snow line.
One of the best looking Ilex at the Arnold arboretum was this I. pedunculosa.
Not a single crispy leaf to be seen. The low temp at the arboretum was -5F (approx -20C)
