Gardeners' Notes:

I have three in various states of growth, in their first year from bare bulbs. One is tall and statuesque, with a thick stalk, and blooming well. I posted a picture of the first bloom, which had the delicate pink with a radiating yellow in the center. I wonder if heat, however, affects the color, since all other blooms have been almost exclusively pale yellow. This note could be neutral because of the bleached color, but as a *plant* it's a worthy addition to my garden. Update, cooler weather has rolled in, and the pink of the Alfred Grille has returned, even more vividly than at first.

Bought from Bloomingbulb in Spring 2006. Color in my picture looks a little faded, I will attribute that to being first year in my garden. Very floriferous. Highly recommend. This dahlia is considered a semi-cactus dahlia, medium.
