nice Agave collection..................is Euphorbia resinifera hardy for you.......I didn't know it could take cold.

Hi Tim,

I am testing Euphorbia resinifera. It should survive about -8C. I cover it with a feather pillow and some plastic cover to keep the pillow dry. That way it survived a longer spell of frost in Dec with temps as low as -8,5C. Now it is starting to deteriorate from the middle, but most of the plant is still alive. The lowest in Jan was -15, but there was about 50cm of snow cover on top. Should the weather get dryer and sunnier soon without any prolonged cold spell, then I am sure it would get through the winter. At the moment I see the chances of survival 50:50.

Anyway, in mild areas, i.e. Cornwall, it would be worth while trying it out. Euphorbia resinifera grows in the Atlas mountains of Marocco where frost and humidity occur in the winter

all the best

Thomas
