Lemons? In Manitoba??

I’ve been reading a bunch of vegetarian and eco-focused blogs lately and have been inspired!  I want to grow citrus trees in my apartment.  My bedroom is the only room that has south windows, and I’m thinking about moving my desk out to the livingroom once my current roommate moves out so that I have more room in my bedroom for plants and other things (dirty laundry mostly I bet).  So far the easiest and most common indoor citrus tree seems to be the Meyer Lemon.  Other fruits that are mentioned are usually key limes, dwarf grapefruits, kumquats, dwarf oranges, or Calamondin.  I figure I’ll start with something easy…ish and see how that goes.  Considering my first attempt at growing herbs from seeds ended disasterously, I’m hopeful but not overly so.  First issue I have to deal with is finding a greenhouse that actually carries meyer lemon trees!  I emailed Screimer’s greenhouse a little while ago and am just waiting for a response.
