Redesigning rock garden
I desperately need help. I just ripped out my perennial garden that I had for 20 years. I got tired of the lack of life and color after their 2 weeks of splendor. I would love some ideas of dwarf shrubs that offer different shapes and color, like low growing blue spruce and shrubs with silvery leaves. Maybe a border along the rocks of light yellow hosta? This area is 20' long by 12' wide and then narrows down to 6' wide in front of 4 arborvitae that are 12'tall. The area gets at least 5-6 hrs. of sun. All suggestions would be most welcomed. We are just north of Boston, no rain for weeks, obvious by the lack of lawn. Thanks so much for any help.
