As I write this, I am looking out at a grove of Metasequoia glyptostroboides, most of which are nearing 20′; in height. All were purchased at Arboretum plant sale over the past 30+ years. At one of the last of the plant sales, I was leaving with my plants and crossed paths with a guy trying to balance his tray of Metsequoias on one arm while tending to a crying toddler. While I held the tray for him, I told him that I had a number of those trees in my yard, purchased when I had crying toddlers of my own. The trees, and the former toddlers, are all now taller than me.
