Snow covered cacti growing in window boxes
As mentioned in an earlier post I'm experimenting with growing peyote (and other cacti) outdoors on my balcony. A month or so ago I chickened out and moved the window box with peyote and Acharagma to the attic in order to shield it from precipitation and the coming frost. Today I'm glad I did as the balcony (and the flower boxes with it) has been completely covered in snow for the last couple of days - and I'm not sure if that would become the peyote plants well.
Echinocereus triglochidiatus covered by snow (with E. reichenbachii in the background)
I'm pretty sure that the hardy Echinocereus triglochidiatus will make it through the outdoor winter experience, and I'll also put money on the Escobaria vivipara (Alberta, Canada) and Escobaria missouriensis (SB204; Mesa County, Colorado) plants as they have already survived a winter outdoors, but I have my doubts about the Echinocereus reichenbachii plants as this is the first time I grow them under such extreme conditions.
Snow covered Mammillaria grahamii
Other doubts are regarding the Mammillaria grahamii (SB 1860; Steins, New Mexico, USA) and Mammillaria senilis (ROG 214; Tecorichi, Chihuahua, Mexico) plants as I'm very unsure if they are able to survive conditions like this. We'll know come spring.
