The Nagami Kumquat is a small citrus tree at maturity, making it suitable for the garden or a container. Mature height of 6-8′ with a 5′ spread, it loves underplanting in the garden. I LOVE choosing a small branch with beautiful petite orange fruit hanging for a fall arrangement. These plants need at least 6 hours of sun and regular water, especially in our summer heat. You will love having a kumquat in the garden.
