Nothing else growing out from between the paving bricks is this colour either. This plant self-seeded two years ago and thrives without watering in blazing heat, its roots in sand, squished between bricks. I meant to dig it out early this spring and plant it somewhere kinder, but I procrastinated. Despite this, the plant grows. It's next to the bench where I sit and read. I figure it now deserves to stay there. It's happy, and pretty, and I'm lazy.
