Hi Pammie, they are officially a short lived perennial, and do come back, but unfortunately they deteriorate year on year, and are usually grown as a biennial, Derek.

Thanks Derek .So my friend and I are both " sort of right "

Saves having an arguement, lol, Derek.

If you trim them back after the flowers have finished, they will grow again and be reasonably good. Dead easy to collect the seeds too.

Mine came back very well again last year but this year very few flowers.

I was given a small cutting from one,last year,and although it has made lots of healthy green foliage,it has only had one flower ...I wonder why? Sorry to hijack your question,Pammie..

They are often sold as biennial, Plant this year to grow next like wallflowers, .hopefully yours will flower next year Bloomer.
I,m never sure if mine just reseed themselves and keep coming!

Thanks Pamg..I think they do reseed,but only found out after I had snipped the only dead flower off ! :o)

Oops. :0))

Oops indeed ! grrr..

You could get a packet of seed now and sow direct in the ground or pot , you would get lots of flowers then, but maybe.....maybe not next year

Thanks Pam,I might give them a miss,I think..as I haven't really got the space to have them..I shall see if this one does better next year..
