lobelia

I've just received my first plug plants.  They're beautiful little plants of a new Lobelia Superstar from Thompson and Morgan. 

It says they are grown from cuttings which makes them more vigorous.  I'm interested to know if anyone has tried to propagate lobelia this way and, if so, did they have any success?

Thanks 

Thanks for your imput.    I'll perhaps give it a go later in the season and see what happens. I like a challenge
