Flower in the rest room

I saw a branch of flower in the restroom where we had a party meeting.

It was a private home restaurant having one reservation a day.

We attended 9 members at the table with a course of formal Japanese dishes.

We all enjoyed dinner in the room like at home.

I really loved the heart warming hospitality and wanted to know the name of the flower.

I asked my friend if she knew the flower.

She has a license of flower arrangement instructor and replied it to me.

She said it might be columbine in English, " odamaki " in Japanese from the shape of the leaves and flowers.

Is it right ?
