No, I don't think it is. The form is not right for Mme Chereau, from my eyeball assessment. Mme Chereau has purple style arms, not lavendar and white.

But I have no idea what I'm talking about, so I would take that with a grain of salt. Perhaps if you could get a clearer photo to show the stitching of the blue on the top and on the falls that would help with an id. How tall is the flower from top to bottom?

I measured the stalk from the ground to around the bottom of the highest bud. It was 33". What other measurements would be helpful? I'll look for other pictures.

Do you see what I mean about the style arm color?

Renee,
I finally had time to take a closer look - and Yes, I do see the difference in the style arms. Good catch! I'll try to be more careful when I take pictures so that I always capture them. I have so much to learn about this. . .

Thanks so much for everyone's help,
Penny
