This is one of the white stonecrop I have .. I'm sure it isn't "Frosty Morn' .. but I would have to dig out the old plant tags to be perfectly in tune to its proper name .. shame on me .. can't manage to do that right now .. but ... it is nicer than I thought it would be .. I'm an ardent fan of the beautiful colours of Autumn Joy ( heck .. it has to be gorgeous if it has my name in it !) So .. not all stonecrop has to go that way ? to be appreciated !
