Every spring I enjoy the smell of sweet honeysuckle creaping over my fence...and then all summer I spend my time killing the creaping vines of honeysuckle, poision ivy and privet hedge. Our city is putting together a list of invasive plants, these are two of the 31 they have in bold. Bradford pears and Cleveland Pears are also on the list.
Birds thrive where these plants are but they also make sure to plant them everywhere they go. Coming from berry or seed pods the new plants are very different from the ones we brought home from the nursery. Bradford pears are taking over our forest...but with large thorns and they stay a shrub thus walking where there is not a trail is very hard.
I can live with the honeysuckle but some of the others like Kudzu, Wisteria and English Ivy just take over. I really feel like I need a herd of goats to keep things in check. Clemson University has a list of the most invasive plants, and you would know I have them all in the yard somewhere.
