Hello and sorry for the delayed answer.
Yes, you are correct, those are indeed Motawi tiles. We installed the following from the "Botanical" Series as accent tiles:
4 x 12 Calla Lily,
4 x 8 Carnation,
4 x 8 Sunflower,
4 x 8 Tudor Rose,
and 4x4 Lady Bell.
The back-splash also includes Motawi 1 x 4 and 1 x 3 trim pieces.
The hood border is made of Motawi 6 x 6 Cyclamen.

All my best and good luck in your project.

Sincerely,
The staff @ Custom Kitchens
