A Gardeners Forum Forums General Discussion The Plants and Flowers Forum Mystery Plants? This year's mystery flower.

This showed up in my garden this year. I have no idea what it is but it's kind of pretty so I was hoping someone here could tell me what it was and hopefully it's not a naughty weed.

Here's a view of the whole plant.


Here's a close up of one of clusters of flowers.


Thanks for looking!

It looks like Cheiranthus cheiri, a wallflower. A bird could have left you a gift of a seed. Congratulations!

It's pretty, such a soft yellow.
