Planting Taller Shrubs behind Shorter Ones
I need the voice of experience please. I know that a plant's growth habit is a range of heights (like 4-6') and widths.
Here's the problem. I want to plant clethras behind hydrangeas. Will the clethra be taller, as desired?
I have one Ruby Spice and another that was labeled RS but turned out to be white! The spot I have for them is in part to full shade. It is close to the hose, which drips when I water, so they should get plenty of extra water. Would you add a third cultivar? If so, which one?
I want to plant these behind an existing hedge (three plants) of Neon Flash spirea. These will be replaced eventually with hydrangeas, hopefully in a similar size, like Annabelles, or a dwarf, like Dharuma. Any suggestions?
