Lobelia, to trail or not to trail ?

I was given some, which is supposed to be trailing,  I planted it at a slight angle, as I do all trailing things. At the moment it is about 5 inches tall, and very upright.    I have never had this happen before, any ideas please.  Mrs Bouquet

Can Lobelia actually "bolt"  They are now still growing taller with lots of foliage, not a great deal of flower.
Would it be a good idea to use scissors and trim them back into a nice shape ?   Or shall I live with them ?  Thanks,    Mrs Bouquet

It will be fine to take the scissors to it.  I used to do the same regularly when I worked at the garden centre when pre-planted containers got a little wild.  Cut back, move off sale for a week or so, then put back out looking like nothing had happened
