Help me to select flowers for this garden bed? (pic)
I am going to plant "New Dawn" Climbing rose along my trellis/fence. I have never planted a garden bed before and I need help with selecting flowers (appropriate for this site and help on where to place them. I would like to stay within 3-4 colors. Dark pinks, purples, whites? I plan to put a small dwarf maple tree in the one corner to fan over one end of the pond. (I'm not overly concerned about any leaves in the pond)because it's just a small pond and I don't mind scooping out the leaves.
I think tall flowers in the back? Medium, then smaller ones in the front? Is that how it is done? I need help with choosing some flowers that the colors will go nicely with the light pink roses. A mix of perennials and annuals would be nice. I have a small backyard so I want to select cool colors. It is west exposure, morning shade and afternoon sun. The bed is 3' x 14'
I already have a lilac tree and a blue mophead hydrangea. We are currenly removing all the old grass and replacing it with rock. As always, thank you for your helpful suggestions!
