Need multipurpose shrub for septic spot?
We have a patch in our backyard that's partial shade and perpetually wet and lush due to the septic tank. It's generally wet year round and the grass is always thick and green. Violets love it around there. I was thinking of doing a bog garden-type deal with ladies breeches and milkweed but I thinking maybe a medium sized shrub would be better. I know any type of willow is a bad idea due to their aggressive nature with pipes, but I was wondering if anyone had any ideas for native, multi-purpose shrubs to plant there to kind of keep the wetness down.
Any ideas? I was considering native elderberry varieties but unsure if that is ideal.
