I have a 14-ft bed facing North and my dilemma is this. The bed gets about 2 hours of morning sun then shade for about 5 hours then about 2 more hours of sun then more shade until sunset. I was thinking about planting hydrangea macrophylla's but was concerned that the on again off again sun might pose an issue for blooms. Does this seem like a good idea? I also have another 14-ft bed but that gets full shade and could use ideas there, no hosta's though.

Oh yeah - I think Purple Gem Rhoadies could thrive in that partial sun bed too.
