Hello!
I am fond of citrus trees and would like to know about hybrids with kumquat.
What do you know about lemonquat, orangequat, mandarinquat,
cirumquat, ichangquat, faustrimedin, citrangedin? Where can I read about these hybrids and see their photos? Are they easy to grow in my "windowsill" garden?
Please, help me. I need true information.

The site below is from one of the most credible organization in the entire world, enjoy the free information:

Interesting to see that the UCR variety collection does not have a Lakeland Limequat, which is a very common "quat" hybrid - Millet

They have about twice more than what they listed, they have not dispayed nor publicly listed them for one reason or another.

Some reasons include: plants are still under disease evaluation, field evaluation, or simply no time to update the website and other publication drawbacks.
