Glossy Buckthorn?

Asked May 25, 2019, 8:18 AM EDT

I live in the north metro on a wooded lot and have been fighting the battle v. buckthorn for several years. I am struggling to ID what I think is Glossy Buckthorn (Frangula Alnus). I've looked on-line but still can't seem to nail it down. Attached are photos of a leaf and well as a photo of the flower (5 petal) which bloomed this week. Many thanks for your help. Channing Riggs

Frangula Alnus Is also called alder buckthorn and glossy buckthorn. It does not have toothed leaves and flowers are in groups of 2-10 but are not spikes as in your photo. http://www.ci.burnsville.mn.us/DocumentCenter/View/2164/Printable-ID-Guide?bidId= Checking the bark for unique markings will help identification. https://en.m.wikipedia.org/wiki/Frangula_alnus Here is a fact sheet comparing buckthorn to native trees. http://www.1854treatyauthority.org/images/IDComparisonsofInvasiveBuckthorn&HoneysuckletoNativePlantsinNEMN.pdf I think your tree is in the cherry family. A picture of a branch, whole leaf and of the bark would be helpful.

Evelyn, Many thanks for your quick reply and all the very helpful attachments. Per your request, I've take a few more photos (attached). The bark looks very similar to buckthorn (as shown in the Burnsville document)--grey and speckled. I also noted this AM that I have some trees that are really tall--30'+. Channing

I think it is choke cherry. Based on leaves, petioles, and flower I am sure it is not buckthorn. See: http://www.restoringthelandscape.com/2010/10/invasive-buckthorn-and-native-look.html
