for studies. has anybody experience with winterhardy/frosthardy exotics, i.e. cacti, yucca, dasylirion, nolina, palms etc. in continental climate. cultivation - 10 year or longer.
I havn't much but when Vic and I visited the USA in Novemeber we saw Sclerocactus Glaucus growing in wet sand at about -5C with a crust of ice on it. There were loads adult plants and hundreds of small ones on the hillside. It was so cold my camera packed up but I know Vic has some pictures.
Also in Utah we saw escobaria, opuntia including tephro like ones just below the snow line, that evening it poured with rain which later turned to wet snow which eventually settled. The plants must have been soaked and then frozen it was so cold.
All this makes me think that we take to much care of our plants. I wonder if this is why I have to graft Sclerocactus Glaucus to keep it alive. Perhaps freezing tempretures and the odd bucket of water are in order.
One thing, Vic and I agreed not to release any location details as one of the sites Vic had previously found was completly stipped of Sclerocactus when we visited in November.
