Calling Mrs P - or anyone who can grow Verbena bonariensis from seed
I know it seeds itself, and it has, but being a tender perennial as an insurance I've tried to grow it from packet seed myself the last 2 years. Not a one germinates- Zilch! Mrs P says in her review that it grows easily, so Mrs P can you give me advice on how you did it please? Or can anyone else who's grown it from a packet?
If I was queen of the world it would be compulsory to grow this plant
