Havana did very poorly for me and did not overwinter. If you want to try the city series I have heard better things about Paris and Hollywood , but overall the series has not done well for me. I bought Rio this year and so far it is doing well. Lipstick is supposed to have good flowering , but I have not tried that one myself. Regina and Coral Bouquet are older ones that have nice flowering.
I hope some of this helped. Different kinds do better in different parts of the country so it would be helpful to know where you are from.
