annuals for an east slope

Doug says that shorter plants such as a short impatiens (Super Elfin mix) do this - nice mounding plant with good season long blooms. Most low-light annuals also have shorter varieties as well as taller (more common) ones.
Any tall plant will indeed reach for light in a low-light environment so stick with the shorter low-light annuals. You may have to hunt around for this kind of variety (big box stores are not going to carry them) or grow them yourself.
I know a lot of folks use Begonia in this kind of condition
Having said that, you can keep taller plants short and bushy by pruning out the growing tips to force them to stay short and produce side shoots instead of reaching up with taller main shoots.
