@Mdios yes, there are members from Canada and UK who grows these and treat these like succulents. For your area this might have to be grown indoors winter time and kept outside when temperature is 50 above. These can easily be grown from seeds too. Most of mine were purchased from Lowe's, Home Depot and Walmart.
