What will grow under blue spruce trees? Need a ground cover

You could try wild ginger or heleborus. Both do well as ground covers that grow under spruce trees!

vinca vine.. google ground covers

Creeping Jenny,Ajuga,Periwinkle

I've always thought not-too-much will grow under evergreen trees due to the highly acidic sap they drip-esp. pine trees. I've seen mostly bare ground under these kinds of trees. I would believe you would need some plant/ground cover which is tolerant of highly acid soil.

Thanks

I planted vinca/periwinkle years ago under spruce and pine and they are still growing. They do grow slowly, but none have died. They are very easy to root so I am putting them everywhere. They also grow great in full sun in the desert.

Goutweed is a no brainer but highly (!!) invasive yet a house nearby me has a ring of it around their Spruce trees and it's beautiful and I never see them weeding it out of the lawn. I've never gone up to see what they actually have done to contain the plan but they most likely really edge the ring's perimeter with a sharp blade (of a shovel) ... in other words, dig a bit of a trench around the outer ring. I admire it every Summer. Ajuga, Creeping Jenny, Periwinkle are all tough plants for shade and poor soil. You could try Pachysandra (a lovely ground cover) but it is slow growing at first. I take cuttings, insert a pencil at an angle in the soil, insert the just-cut piece and keep watered. It will definitely take if you remember to water, you save money and end up with more ground cover.

Can you share how you 'take cuttings' of your Pachysandra...we just planted a few under our red-bud tree and I could take cuttings from them

I have a very large pine tree that I planted a variety of hostas under and they are doing very well. After two years that's all I see under the tree and it's very pleasing to the eye. All mine are different shades of green to lime green.
