This may be a tricky question, and it may not even have a definite answer, since all lantanas bloom profusely. But in your opinion, or from your experience, which lantana shrub/perennial produces the most amount of blooms in a single flush and re-blooms for the longest amount of time?

I have heard some people say that Miss Huff Hardy is the most prolific bloomer and blooms for the longest period of time, while others have said that New Gold was the most prolific bloomer for them. My Ham n' Eggs lantanas are prolific bloomers, but they have to be dead headed in order to keep getting lots of blooms. (Dead heading gets to be very time consuming when you have hundreds of fading blooms.)

So which one has been the best for you?
