Nagami Kumquat

The Nagami Kumquat Tree

Buy Nagami Kumquat Tree 

Nagami trees are a commonly grown kumquat in containers. Their compact and upright growth habit make them easy to care for.  With prolific blossoming during the summer, this tree makes for a very attractive and wonderfully fragrant plant.  During the month of August in Minnesota, there were three flowering cycles. The fruit remaining from the first spurt grew significantly through this period.

I’m a fan of kumquats. They taste unique, you pop them right into your mouth, and are harvested before other citrus ripen. It’s nice having citrus ready to eat all throughout the year!
