Author's Notes
For many years I drove past a very old Harry Lauder's Walking Stick. My guestimate is that is it was around 5-6 feet tall by 6-8 feet spread. The stem looked like it had a diameter of 4-6". The owners shortened many of the hanging branches so they could cut underneath the plant. It truly looked like a plant that was planted upside down. This plant has been lost due to road expansion. I think this may be a short lived plant. I have observed them one year at a botanical garden and the next year they are gone.
