Drosera ordensis Fails in Cool Vancouver Nights: Needs Hot House Conditions

A Vancouver, BC grower’s D. ordensis (woolly sundew) produced leaves but no sticky glands for a year. Winter: west window. Summer: morning/evening sun, midday shade. Rainwater (tap 15 ppm).

Jeff Dallas: D. ordensis is a woolly sundew from N. Australia—needs bright sun, >70°F, tolerates low humidity. Cool BC nights are the problem. In Oregon, they need hothouse conditions in winter. Not a good windowsill candidate.
