I have no idea how they do it. I had two empty pots from the basil the
year before, and the red valerian moved in. It never comes up in
cultivated soil for me.

Red Valerian (centranthus ruber)is also known as Jupiter's beard and is
a wasteland plant.

Valeriana Officinalis is related but not a close cousin.

The former is (IIRC) edible. The latter, sedative.

We had valerian (officinalis) with red, white and orange flowers. The
reds survived.
