The above site is stock full of cool information and I just read that there is an even better cultivar at fighting lethal yellowing.
In the 1950's here in my area of Florida, the Gulf Coast, city streets and beaches where full of coconut palms until the lethal yellowing came through and wiped them out.
Wow!! They are gorgeous! I've never seen them here. Looks like you have a great Flower Show there!
