Water Lilly looks to be insanely over powered in her bloomed form. A 15% whole party defense boost is nuts for a 5 star unit? Her skill proc rate's high too. Top pick for an evasion unit.

Oxalis is a pretty decent buffer girl too. She's not an uber buffing hyper zombie like water Lily but she hits hard, gets a 1.2 skill activation in her bloomed form and is a cutie pie.
