I am still subscribed to the Friends of the National Arboretum group in my Home town Washingotn DC. So I decided to look up the park today and see whats going on. I discovered there tour planner https://www.usna.usda.gov/abe/ (you might need to use Internet Explorer) and if its not lying to me I can’t wait to get back to DC.
Why I hope its not lying is because they have all these marginal plants I have been wanting grow like Morella rubra and Acca sellowiana. Sure I was going to try to grow them anyway but if I can see them alive in my Zone I won’t be able to stop.
