I am working on a garden design for the park entrance near my house. It's a pretty big job and I was approved for a grant, however I have to use half natives. My only problem is that the ONLY native I have that will work are black eyed susans (a lot of them).
The plants I have selected to work in this drier spot are:
Nandina Domestica (3 - the only shrubs in the entire bed)
Sedum 'Autumn Joy'
Calamagrostis 'Karl Foerster'
I looked at substituting Shanendoah Switch grass for the calamagrostis but they don't look nearly as nice and they tend to flop over more (in my experience).
As much as I like using some natives, in this layout, they won't work as well. Any ideas on how to substitute any?
I do NOT want any other shrubs b/c this area will not get regular pruning and we don't want shrubs that will get out of control.
