I think I probably can grow the Michelia in ground here, Lin, but I want to grow it a little bit bigger in a pot before I commit it to a spot in my jungle. It will have to compete with so very many oak tree roots that I think a bigger plant will stand a better chance. I got this one last fall and it is only about 18in. high and wide.
Right there with you on the blankies for plants! I have imported all my orchids into the house for this week, and it's a jungle in here, too. We won't get quite as low temps as you, but mid-40's really can put a stop to growth on a lot of my tropical divas so I do protect a lot of things. Sunny and lovely out there right now, but brrr! It sure does cool off fast once the sun goes down.
