Dogwood pairs pretty nicely with Mei, from my experience. It pretty much turns the solar drive button into an "IWIN" button on demand(if an encounter is taking longer than you like, you're just one click away from sweeping them off the board). Her attack stat is pretty high as well(on par with Cattleya), so her special can hit like a truck.

I wouldn't say Dogwood is a must-have or top-tier by any means, but she does have her uses.
