Well it varies! My favourite which we bought last year was £15, ($ 28) it had a good number of flowers but was rather “leggy” and so in the “sale” at half price. This year it is doing well but still a bit “leggy”. I think when it has flowered you can prune it so it becomes more bushy like this good one which was priced at £180 ($335) this year. Needless to say it did not end up in our car. I have posted a "detail" picture too for good measure!
PS We do not have shares (stock) in this company by the way!!!
