I have never had much luck with 'Lemon Chiffon', had it 2 times and dies over winter. 'Circus' I bought as a plug one year, died over wither. However, received a start from a friend last year and it's doing well..
Have you looked into any of the cuties series?
This is a nice bright green one, stays smaller for containers. The lighter ones have a tenancy to get rust. However this one is has good resistance.
I still have 'Lava Lamp', no luck with 'Marvelous Marble' here in Washington.
