Hi Terry,

Had you repotted the plant after the last flowering? I have just read from
the 'Gardener's World' April 2005 issue (p.82, Martin Fish) that
"These plants flower much better when their roots are restricted, so avoid
growing them in too large a container. Ideally, buy an established plant
and keep it in frost-free conditions during winter."

I hope the information can be helpful.

With regards,
