The Centennial Variegated Kumquat is larger and sweeter than most kumquats. Some believe it’s a cross between a Nagami Kumquat and a mandarin. Compared to the Nagami, the fruit is larger and tends to be a little sweeter due to thicker skin.
So if you’re looking for a kumquat with less tart, this is a good choice. The tree’s variegated leaves and fruit make for an attractive plant too.
