I can confirm that individual plants can definitely make it to at least their 3rd year - and it wouldn't surprise me to hear about them going beyond that.

I have seen this same behavior in mullein. Zion National Park had a control program, and one year, in some areas, instead of digging out the roots, they simply wacked off the flowering stalks. The next year, the plants came back like Godzilla. It was nothing short of frightening.
I don’t know if individual plants can hang on for more years, but I wouldn’t be surprised if at least some didn’t make it to at least 4, if thwarted in their reproductive attempts again.
I suspect a fair number of biennials have this kind of a fail-safe mechanism. Natural selection really does favor successful reproduction rather strongly :-)

Thought you two might know something about this.  Part of discussion with Mid_Atlantic Invasive Plant Group (includes Ohio and east).

As we begin to wrap up our Garlic Mustard season, I've become fascinated by the resiliency of the species.

I'm seeing tremendous numbers of garlic mustard adults surviving into a third year if their stems were broken off in the year prior. Their wounds simply heal, their roots become massive and they sprout new stems and seeds.

Here is a photo I took today in Beltsville of a specimen that survived our great Garlic Mustard pull of 2014, healed, and re-emerged:

Would this not imply that these plants can come up again, possibly a fourth of fifth year if seeding was unsuccessful?

This has me wondering if plants could bounce back after damage from say, an introduced biological control.

Any thoughts?
