Descurainia sophia in bloom

The flixweed (sagesse des chiurgiens) is in bloom, and starting to set seed. Now that it has seedpods, I know that this is non-native D. sophia, rather than native D. pinnata (see details on distinguishing the two). A shame. I do like the lacy bluish foliage.

Descurainia sophia: foliage

Descurainia sophia, known in English as "flixweed", "flixweed tansymustard", "herb Sophia", or "pinnate tansymustard", and in French as sagesse des chirurgiens, sisymbre sagesse, or sisymbre sophia, is an annual or biennial native to Eurasia. At this stage of development, it looks very similar to the native D. pinnata; later on it can be distinguished by its seedpods.
