Limequat is a unique citrus hybrid between a Key lime and a kumquat, combining the tart flavor of lime with the cold tolerance and edible skin of kumquat. The small, oval fruit can be eaten whole or used like a lime in drinks, desserts, and cooking. Limequats are highly productive, ornamental, and perfect for containers, making them a great choice for patios and small gardens.
