Pacific Northwest Native Plant Profile: Western Wild Ginger

I have an old Douglas Fir that would love some company underneath and against and around it and I just got some wild ginger in a pot that also has inside out flower and trillium from Bosky Dell. However because of the canopy cover I would call the area beneath the tree dry shade. But if I plant things closely (goats bear， ferns) and mulch well (there is already a good amount of forest duff below this Doug Fir) and water well for its first season or two，。

or should I put these plants in a different locale? Thanks so very much! ， do you think wild ginger would establish ok underneath this tree。
