Small toadflax
The Small toadflax (Chaenorhinum minus) has been found on campus.
In fact it’s been here for a while according to the greenhouse staff who see it come up every year in the gravel strip between the cold frames and the greenhouses.
It’s an annual so the plants set seed each summer. These germinate in the spring to produce a new crop of tiny, pale snapdragon flowers. The plants are typically only 5 to 15 cm tall with tiny linear leaves so they are easy to miss.
