Thanks.
Well this one is first flowering at 18 months so it has only one bud on a stem barely more than 12". The flower is large and the stem was quite lax at the top, under the weight of the flower. Looking at the stem now, with petals dropped, it seems quite upright but not stiff. I hope it will mature strong enough to support the flowers. I'll have to keep you updated next year with photos of your grandkids as they grow up.
