What to plant in Western Canada

I was wondering what you all would recommend for planting at elevation between 700-900m southern British Columbia. It has been fairly dry here for a good portion of the year ,lots of water around just no precip.. Frost comes early at times as soon as early September. And snow is gone late April. It needs a early finish and has to be a good strong outdoor strain that requires little maintenance. I can start early indoors. And would like a plant under 6 feet with a good yield.
