4 Might 2023
As we speak, Might 4, is identical day of the 12 months that two redbud (Cercis canadensis) specimens have been collected at Powers Run in O’Hara Township, Allegheny County someplace close to this dropped pin. They’re pictured side-by-side above from the Botany Assortment on the Carnegie Museum of Pure Historical past.
The specimen on the left is simply starting to flower on 4 Might 1915. The specimen on the best, collected 102 years in a while 4 Might 2017, is in full leaf with incipient seed pods.
It’s been six years for the reason that 2017 specimen was collected and in that point local weather change appears to have sped up. How are the redbuds affected this 12 months? Did the chilly moist climate gradual them down? How huge are the leaves? Are there seed pods but?
As we speak’s the day to verify the redbuds and see how a lot our loopy local weather change climate has made a distinction in 108 years.
p.s. On my journey to Enlow Fork on 26 April I famous that, surprisingly, there was no huge change to blooming occasions of Enlow’s flowers this 12 months.
