I made a small
hugel bed out of pine, mulched on top with pine needles as well. It has low bush blueberries under planted with
native Oregon strawberries and nagoonberries...and in the back it has black currants and red currants. Also stuck a bu ch of columbine here an there, too, as they are lovely and tolerate acidic soil.
Here in Oregon we have high-acid soil, and much of the free mulching get is coniferous. I think the following perennials, which all grow happily in pine-mulch rich areas of my
yard. would all be very happy in your pine bed:
Gooseberries
Currants black red white pink
Jostaberries
High bush cranberry (viburnum)
Low bush and high bush blueberries
Salal
Thimble berries or salmon berries (in shade)
Lingonberries
Cranberries
Nagoonberries
Strawberries
