Oncidium and then Oncidium Bride as the 6* would be good choices. Of course I own them both so I'll be going something else.

Cyrtanthus she is pretty good :3

Dianthus (Shrine Maiden) - Shiny fae girl, her durability, counter and health drain make her a Kerria lite
Cymbidium - Gorgeous Glasses Girl, first turn fatality
Wax Vine (Xmas) - Putting the love of Christ directly into your heart. With a chainsaw!
Ornamental Kale - Thicc, a piercing wax vine (Xmas)
Madonna - The Dazzling Sun, good solar sweeper. Dogwood lite

. . . and like a dozen others I'd really like.

I already have Scarlet Tulip, Heather, Stewartia, Lagurus [HW], Greenbell, Lantana and Aloe, who are all good five star girls.

Of course ymmv. Cyani Cornflower is of my favorites and she's barely even a four star unit.

5* I'll almost certainly be picking up a dupe, or the 3rd shrine maiden, if it's a dupe part of me would want to go rose to get her 3rd equip slot....

6* It's either my shrine maiden or....I'm considering a dupe, Likely Alpine as I've max ampied her

Right now I have 6*'s that don't make it to my main rosters

It's that or pick the most powerful 6*

....Whale ship I'm struggling on the later stages - I'm so coin starved I can't get blooms done....it's rough

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.

15%? I see 10% ATK and DEF.

I usually use the wikia since it has semi useful information on the bloomed abilities of units that don't yet have a bloomed form on nutaku. There's no real telling if or when Nutaku will update those girls but it's worth looking forward. 10% defense to full party is still a hell of a buff to get off a five star. Better than a 15% boost to three since it's a controlled distribution and higher average defense increase.

If you are going to use the wiki for info like that, use the japanese wiki (in japanese) and verify when the buffs occured. They pretty good about documenting that.
