Amerian Bells - Clematis section Viornae

Image
Our Friend Carol Lim has published a great web site about the North Amercan Species of Clematis in Section Viornae . Often called "Leather Flowers" or "Americal Bells" many species are of very restricted range so few people see these beautiful flowers in the wild although hybrids using the red genes from C.texensis are common in cultivation. We have several plants of, what I am pretty sure is, C. addisonii in our garden. I took these pictures in our graden the last week of May and the first week of June 2007. I think everyone should try to grow these plants when seed is available or nurseries sell plants . Carol has links to some nurseries on her web site. __________________________________ Update: Link to Larger version of my Pictures of Clematis addisonii.

A Male Rufous Hummingbird visited our garden for a few days

Image
We had a beautiful male Rufous Hummingbird show up at our house last Wed. afternoon, July 29, 2020. He spent his time guarding our nectar feeders and keeping away all of the local and migrant ruby-throats. According to Scott Weidensaul this was the earliest "Fall" record for this species in PA. Several close friends got a chance to see him and we were hoping more people would get a chance spread out over time, but he was only here He was here through Friday evening. On July 31 he left after being banded.  We invited Sandy Lockerman and her husband to come and try to trap him and band him because I think that it is a good thing to try to understand the changing migration patterns of hummingbirds from western North America like this species. I hope that he may be re-trapped sometime and contribute to our knowledge base about these wonderful creatures. Sandy tells me that hummingbirds usually stay after banding, but this one took off and hasn't been back, Mike Slater
