Gardeners' Notes:

This outstanding daylily grows well in our Zone 4 sandy soil. Extremely beautiful, fragrant flowers have a bit of ruffle, yet retain grace. The color blend can't be beat, with depth, mystery, and brightness all at once. Visitors all want it. This is one of my top ten daylilies.

Survived the Maine winter in the sheltered section after being planted in Sept which is frost time around here. Bloomed early mid season a shade not usual for the time and it was just gorgeous for a first year bloom.

After many years of wanting "Smoky Mountain Autumn", I got it at the end of summer in 2006. It bloomed in 2007. The flower shape varied a bit from bloom to bloom, but the color was a gorgeous blend of peach, coral and dusty pink with a deep golden throat. I was very happy with it! Having seen all the different photos of it posted on this page, I'll be interested to see how mine looks in 2008.

I love this one. Starts out the day with a pinker tone and turns to a smoky peach by days end. Gorgeous.

The image by Carolann, Nov. 14, 03 of Smoky Mountain Autumn appears to be the most accurate of the 6 images shown. Grows well here in Zone 7 as well as mountains of North Georgia.
