Baptisia australis & Perovskia atriplicifolia
I am in zone 6b in South-central Kansas. I had some large (7' wide) lantana planted along the southern wall of my garage but want someting more cold hardy. This part of my lawn has very sandy soil and receives full, blazing sun from sunrise to sunset as well as reflected heat from the side of the garage. (Now you know why lantana do so well there.)
I am considering planting Baptisia australis and Perovskia atriplicifolia together. Does anyone know if these two plants would grow well together under these conditions or would one tend to smother the other one if one grew faster than the other? Any comments or opions would be welcomed.
