@spendius,
A few months ago I bought a 4" pot planted with an apple mint plant. It's doing ok, needs a tree. But a few weeks ago, some aggressive wee greenie started to move up in the world, and quickly continued. It looked familiar, heart shaped leaves, but a lot of plants have those. A vine that wants to entwine my olden metal chair. I looked up heart shaped leaves but, eh.
So today - I see it's a morning glory. Luckily it's in a pot. I love them from afar, but I have enough trouble with various prickly weeds to control, even though morning glories are not apparently the weed of the universe here in New Mexico that they can be elsewhere.
Still, back in the early seventies, when I and a business partner/friend had what was my first art gallery/studio, the owner of the building had a large back yard, and in the yard was a church, or church parts, from a broken down old church in Spain. Plus, a garden shed. And over all those marble slabs and the garden shed, were morning glories being glorious. Beautiful memory, so I smiled at this new plant by my front door.
