Phenology updates: Mile-a-minute, Oriental bittersweet, Tree of heaven, Privet, and Ivy


Mile-a-minute (Persicaria perfoliata) – [plant with triangular leaves] seedlings growing. Please note, AOWCP is still tracking populations of this species.  If you see any please report it to


Oriental bittersweet (Celastrus orbiculatus) – seedling (above), flower buds (below)



Tree of Heaven (Ailanthus altissima) – leaf out


Privets (Ligustrum spp.) – flower buds forming


Ivy – (Hedera spp.) – Interesting set of photos demonstrating why it might not be a good idea to landscape with ivy.  This ivy happens to be growing behind the siding.  Second photo is almost 4 feet above the ground

  1. is that boston ivy? I hate that stuff, don’t know why anyone wants that stuff growing up their brick houses and a friend of mine had some planted in her yard and it spread into the surrounding woods around her house, yuck, I will have to look up the mile a minute and privet to see what exactly it is, your pictures were okay but a bit hard to tell what the flowers looked like on the privet. amazing how many plants get out of hand, I have hottatunyia and love it but it is confined as I mow around it all the time so it cannot spread out beyond the house area, it smells wonderful, I have two kinds and its beautiful. and edible too.
