One real find at the Arboretum has been seven son flower (Heptacodium miconioides). Everyone tells me it flowers in late summer but our plant was in full bloom May 29, which no-one who wasn't there believed. I had to display the photograph with its date on my DSLR to convince the crowd. The flowers are white and reminded me of miniature azaleas. Currently the plant is entering its second month of second bloom, though bloom is not the word. Rather it has turned pink thanks to numerous, narrow calyces that have opened flat like aster petals. If that's not enough, it also is producing a few true flowers. Now the skeptics are talking about propagating it.
