Lovely photo's Greg, and I've been meaning to say how envious I am of your new large tubs, I saw the pictures a while ago but keep forgetting to say
None of mine are really huge. Silverline was my biggest at just over 6 inches but that bloomed this summer and with no offsets either
I have Othello which is meant to grow pretty big, but mine are both less than a year old and we didn't have ideal Summer conditions this year to say the least, so I'm hoping they will expand a lot next year
