Today’s photographer, Gary, provided a lot of commentary with his image, so I’m going to liberally cut-and-paste from his message. He writes:
The photograph was taken in my Pollinator Garden in Davis, CA. on 12/3/07. The hummingbirds like ‘Christmas Cheer’. The first time that I saw a Kniphofia ‘Christmas Cheer’ was on a bicycle ride through the UC Davis Arboretum‘s Storer Garden on a foggy morning, and when I saw it I said “Wow!” It looked like it was lit up. I had get one of those. I ordered it from Cistus Nursery in Oregon, the “Home of Zonal Denial”.
I also appreciate the following links that Gary sent along: information on Kniphofia ‘Christmas Cheer’ from a hummingbird listserv, the African Garden with reams of Kniphofia information, and, finally, the weblog Asphodelaceae Anonymous (which was new to me, but sadly doesn’t look like it’s been updated in some time).
