Summer, Summer, wherefore art thou Summer?

I've been dreaming of my summer garden for a while now.  That's the trouble when the snow is pile high and I've gotten an itchy green thumb. i've started two types of flowers inside already: bee balm and coreopsis.  The coreopsis has already germinated, but I'm worried about the bee balm.  I have a little less than a month to go before I plant anything else inside, but I wish it was sooner.  I love the snow, but the growing season is so far away.  I've been using my Punch! Landscaping software and Growveg website to plan flowers and veggies for the summer, but it's not as nice as the real thing.  Here are the plans for this summer's garden, though some of the plans for the backyard will be years in the making.  I hope you enjoy the visions of summer!
