The most cold-hardy citrus tree you can buy!
If you can say the word 'kumquat' and not instantly have your mouth start watering, then you've never tasted these little sour/sweet power bombs. Kumquats are small citrus fruit - no bigger than a golf ball, often as small as a half dollar - that pack a BIG citrus taste. You usually pop the whole thing in your mouth.
Marumi Kumquat, Fortunella japonica, is a breeding breakthrough and a boon for gardeners, especially those in colder northern climates. Of all citrus - oranges, lemons and limes included - Marumi Kumquat will survive the lowest temperatures. They often don't show any damage even when the temps get down to 10 degrees. At 0 degrees they will lose their leaves, but by spring, the leaves will grow back! This winter dormancy is pretty remarkable and unheard of in other citrus trees.
Marumi Kumquat has small leaves and round fruit with thin, sweet skin that is edible. No need to peel. These trees do great in pots by a sunny window so that you can pick a few kumquats to snack on any time. They start producing in late fall and by Christmas you can have boughs of greenery with natural orange 'ornaments'.
Nature Hills prides itself on the quality of our trees. We make sure to prune our citrus trees for maximum branching, and ensure that each tree is well rooted into each container size we offer. We know that you won't be disappointed with the Marumi Kumquat tree!
