Dear Desi,
Thanks for your email. I do not have any specific information about the germination of C. Horridulum. We have worked with Pitcher's thistle for quite some time.
We cold stratify the seed for three months in moist sand.
Sorry that I cannot be more helpful.

Hi there,

My name is Desiree Yanes and I am a vegetation monitoring technician at NYC Parks. We are currently working on a conservation action plan for Cirsium horridulum var. horridulum and we are in need of some information that is not currently available. Could you please send the message below?

I am looking for information on propagating Cirsium species, specifically Cirsium horridulum var. horridulum. We are working on a conservation project for this species and do not currently have a propagation protocol. If anyone has information that would be helpful in the propagation of this species, please contact desiree.yanes at parks.nyc.gov<mailto:desiree.yanes at parks.nyc.gov>.
