Maybe not ,but it was rampant in our lawn in our last house. Whether that was from seed or bits falling into the grass and rooting, I would not like to say.

It spreads by its spreading roots so should be OK in a trough. Ours is in a dryish, shaded area of the garden and has not spread too much in 10/15 years.

thanks to everyone, it can stay in the trough and I will enjoy the lovely blue flowers
