Smyrnium Perfolatium: friend or foe?!

Hello all and hope you’re staying safe.
I was kindly given these, but I’m unsure as to whether or not they’re too invasive for a garden, or not.
Any tips gratefully received 🙏🏻

They are biennial, so flower in the 2nd. year and then die. They may seed around a bit, but not a problem.
