Nov. 21st Meeting - Local Ecologist to speak about new possibilities in biocontrol of invasive species .


Richard T. Gardner, "Non-native Invasive Plants." 

Non-native invasive plants are a major problem throughout the world. This presentation will identify major local invasive plants, discuss their biocontrol and bioeradication and finish with new exciting local developments in the field which have the potential to radically change how non-native invaders are dealt with.

A very cute little native Goldenrod

Image
A very cute little native goldenrod is found along the lower Susquehanna river growing in crevices in the schist bedrock. It is now called Solidago simplex ssp. randii v. racemosa ( USDA Plants Link ). The name is almost longer than these plants are tall. I would expect that would be bigger when not growing in a tiny crack in a rock but I do want to try growing it in a trough or rock garden. This species is on the PA endangered species list as this is the only place it is found. It is on the list under the name: Solidago spathulata DC. var. racemosa (Greene) Gleason Sticky Goldenrod status: Endangered Variety racemosa grows from Tennessee to New Brunswick and Nova Scotia and it is considered threatened or endangered in many states. Other varieties of Solidago simplex ssp. randii grow as far west as Lake superior. Sticky Goldenrod grows on the flood scoured bedrock where competition is reduced along with many relict prairie species like Big-blue-stem, little blue-stem, Indian gra...

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

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.
