For some years St. Louis area organizations involved with plant life have been publicizing the urgency of erradicating the bush Honeysuckle which grows prolifically. Not only does it grow like crazy, it takes over the landscape and suffocates everything in its path. It also is a nice companion to the out of control weed vines, another huge problem.
Originally brought to the US from Europe and Asia as a sweet smelling ornamental hedge, the Honeysuckle is now a huge detriment almost everywhere. We've been working on removing as much of this annoying plant as we can here at the seminary but as often as they are cut down, they come back with a vengence. It takes cutting them to the ground and then poisoning the stump immediately. Then starting all over the next year.
The good Honeysuckle brings (great spring frangrance, pretty red berries fall) is negated by the stranglehold they put on the landscape. We had it in our yard in Collinsville but have successfully removed all traces by constant vigilance. In large areas like Forest Park and the seminary campus it is not that easy.
