Eck, that's awful. Are you sure they don't come on a later log in card? I was sure I had seen a wiki page about her blooms at some point but there actually doesn't seem to be one now that I've double checked. :/
Poor Alstroe.

So apparently the DMM version has her unique dress/skillblooms, and she's the only 6 Star to have unique blooms.
They come as level up bonuses for level 175 and onwards, but I'd need a DMM player to confirm this.
