Ya never know...a horticulture prof friend of mine was visiting and I showed him a lovely little volunteer tree...I thought it was pretty and unusual....he said it was unusual because most people go out of their way to eradicate it as it is horribly invasive and spreads by seeds and underground runners....I cut it down and have been systematically killing off the suckers from the roots and sprouting seeds for the past 3 years....much like the lovely but invasive LimeLight Artemesia....
