I have 2 D. Spatulata and 2 'white leaf' D. Capensis . Do either of these require dormancy? I currently have these guys growing outdoors in full sun. The spatulata is growing at an alarming rate with new plants popping up constantly forming beautiful clumps with globs of purpleish dew. The Capensis is growing nicely but the stalks are a bit short, I'm assuming because of being in full sun. What conditions do these guys like during winter? I'm in Buffalo, NY where we'll get 20F temps and lower during winter.
