A few weeks ago, I discovered a mysterious stranger in my front yard. (Wait, it wasn’t creepy!) I noticed a large plant enthusiastically outpacing the rest of the yard’s late spring residents. It was obviously Something, but what? Rather than give the plant a chance to bully its way to King of the Garden I dug it up, put it in a pot and gave it a home in the back yard. Whether that home would be temporary was to be determined. What the heck was it?
I can now answer that question. (I’m sure many people would know what it is straight off the bat but I did not. Learning, it’s a beautiful thing!)
Meet the (checks the plant ID app, which is probably right?) Treacle or Wormseed Mustard plant. This is Erysimum chieranthoides, also known as a Wallflower. And here I thought that was just a metaphor.

It is weedy in looks and habits, which doesn’t typically bother me that much, but it’s also a wee bit poisonous and very bitter. Most animals avoid feed contaminated by this plant’s seed. Sounds unpleasant. I’m afraid I will have to say thanks but no thanks.
Also, my helpful app has another poem for us. It’s not actually about this plant but what the heck. Enjoy!
And then along my picket fence
Where staring wallflowers grow–
World-wise Old Age, and Common-sense! –
Black bonnet, nodding slow.
