Verbena bonariensis "Lollipop"

Loxley

I love V. bonariensis but its self-seeding is on another level in my garden. Does anyone know if V. b. "Lollipop" is sterile?

Would save me a fair bit of weeding!

No, not sterile I’m afraid Will. I recall I read somewhere that it does not come true from seed, so offspring will be taller.

Thanks Nollie.
