I bought mini-plugs of trailing lobelia - Sapphire. Potted them on and nurtured them. Hardened them off and planted in tubs (like you do). I ended up with multi-coloured, which is not what I wanted, and some of the plants weren't trailing, either.
I took flower samples +original label back to my local GC. They were apologetic, and gave me a dozen more mature specimens. I managed to wiggle out the wronguns and replace them, and thus far, it's looking good!
Bouquet to West Somerset GC, methinks for at least helping to put it right.
