What to plant under a large Spruce?
We recently moved into a new home and I'm looking for planting ideas for a large space under a Spruce tree. It's a huge one (40-50 ft tall) and the ground space under has a 10 foot circumference. The lowest branches are well above the ground by 10 feet or so. Currently there's nothing growing just a carpet of needles. I've heard the ground may be acid and not much will grow. I'd like to border the area with recessed brick and create some kind of "garden". Any suggestions? I was thinking of a green ground cover with something like Liriope or ferns and Lily of the Valley throughout. Any ideas? Do you think they will grow?
