Q.perennials under spruce trees
What kinds of perennials can be grown under spruce trees? Nothing seems to grow there except weeds. Trees are trimmed up about 8 feet.
Look for shade perennials.
Low growing ground cover plants may be the best choice.
I grow Hosta, Sweet Woodruff, and Snow On The Mountain under mine in the same zone.
I have listed lots of links to get you started and planning!
Best of luck.
