That was the same for me, when I got my Cattleya. Congratz !

Also I got Fritillaria as a refund for 300 gold there is 3 hours due to an in game bug
They send me a message :

Hello Pimers,

Apologies for the slow reply.
Unfortunately we as a game-team cannot refund platform gold.
To compensate you for the trouble, please pick any Flower Knight you want and we'll send her your way!

Regards,
The Flower Knight Girl Team

So I chose Fritillaria and :

Hello again!

Fritillaria has been sent to your Gift Box.
Check her out!
