I have mixed emotions about Morning Glory's. They are beautiful and they draw in all kinds of pollinators. They even seem to catch the eyes of the migrating hummingbirds that pass thru here. Now that's the up side.
But there is also a dark side. They get into my garden and choke out my beans and then they attack my staked up tomatoes and if I let them, they'll kill my tomato plants. They seem to want any high points in the garden and, so, they dominate the tops of stakes and any other supports for the other things being grown.
I was down in the garden area today and was pulling the last of the 6' stakes I use. Of the 150 or so stakes, and even though I cut them out all season long, there were 63 that had old dead vines from the Morning Glory "invaders" wrapped around and choking the poles. They are pretty. They are colorful. And they are fragrant. But for me, they are mostly a pain in the a$$. They might make reasonable compost if I throw in enough bovine droppings.
