Container gardening-Western Exposure

Doug says - just do it! I rather doubt you have enough sunlight (3 hours of full sun) to really get tomatoes and roses into bloom but you can only try. And get out the insecticidal soap or the water jet for aphids. Insects are a fact of life in gardening - we all deal with them (more or less) every year.
If you think you have the light - then grow what you like to see blooming and what you like to eat. You'll very quickly figure out what works or doesn't work but that's the starting point. Grow what you like the look of - grow what you like to eat.
