Hi, I am from Holland (the Netherlands) and I did indeed manage to grow a Myosotidium hortensia in a medium large pot. The pot stands outside in the half sun and does well. Now winter is coming here soon. My question: can a leave the pot outside? Or should I take it inside and when, at which outside temperature: minus 2 to 4 or minus 4 to 6 degrees Celcius? Thank you for giving me some expert advice! Regards, Renée Elzinga
