That time I discovered another invasive plant

If it behaves like an invasive plant, it probably is one. (And I should look it up.)

There’s this flowering plant that pops up on the river bank in summer in front of my neighbour’s house which I haven’t really gotten around to identifying. I suspected it might be somewhat invasive but because I haven’t seen it all over and I’ve been too busy planting things I haven’t taken the time to find out what it is.

I noticed a few more of the plants when we went on our walk the other day, and I took a few pics and posted them online to get help with an ID.

Turns out they are called “four o-clock” (or Mirabilis jalapa) and are a NEMBA category 1b invasive.

I could kick myself for not looking them up sooner – I could have cut the ones near my neighbour back before they went to seed and started spreading. Oh well. More work for next summer I guess.

I already know it’s gonna be a mission to control them – they grow from tubers and the few I have tried to uproot already were a mission to get out the ground. Where I did a hack/bad job they grew back – and quickly.

I reckon my neighbour will be bleak if (when!) I start removing them too, as they probably think the plant is pretty.

I wonder what would be a good indigenous replacement? Any ideas?
