Hi Kcg and welcome to GoY. The snag with growing anything under a row of conifers is the soil is going to be dry and impoverished from the conifer roots. You could try Vinca minor (lesser periwinkle), also check out shade loving plants by going to the bottom of the page and clicking on 'S'.

Or try Cyclamen, Euphorbia robbiae or , dare I suggest it, ivy.

I would suggest vinca or ivy as well. Start them away from the trees in reasonable soil and train them in the direction you want them to go

I go for Euphorbia Robbiae. A bit slow starting, but when established they spread quickly and are always green. They have loads of lime green flower like bracts in Spring too. Just watch out you don't get any of the milky sap on your hands as it can damage your eyes if you get it in them.

What about symphoricrpus,[ the snowberry], does well in dry shade, have planted them under the dense canopy of ceders and they seem to thrive, nice white berries in the autumn/winter.
