syngoniums:

Echeveria cante is by far the most blindingly white plant I own, even more so that Dudleya brittoni. That may be down to the fact that its farina seems to stick tighter to it, especially in the rain. The dudleyas are very dusty. The second echeveria is so far unidentified (maybe ‘Etna’)? I’ll have to see what it looks like after some more time in full sun.
