Marumi Kumquat Tree For Sale

Available in both 1 gallon and 3 gallon sizes.

Marumi kumquat or Round kumquat is one of the recognized species of kumquat (Fortunella japonica) and originated in Japan, hence the specific name. Superficially it resembles Nagami kumquat, except being smaller in all aspects and with round fruit rather than oblong fruit. Leaves are lanceolate and dark green, about 1-2 inches long. The plant tends to hold leaves upright at sharp angles to the stem. Tree size is about the same as for Nagami, and Marumi will best be used in the landscape as a large shrub rather than as a tree. If growing as a commercial crop, Marumi could be planted much closer together than would be advisable for standard citrus.

Fruit are about one inch in diameter and round, with a thin, sweet rind and abundant, sour juice inside. Marumi is sweeter than Nagami, and the light orange fruit resemble miniature sweet oranges on the tree, but the fruit lack the intense deep orange coloration of Nagami. Because of this, Nagami has become the preferred ornamental kumquat. For this reason, and because the fruit are not as sweet as Meiwa kumquat, Marumi often gets ignored, and can be difficult to find in a nursery. However, what it may lack in color or taste is more than compensated in terms of cold-hardiness.

Even as a small plant, Marumi is extraordinarily cold-hardy, enduring low teens F with just defoliation, and rebounding in the spring with foliage and fruit. It should be an essential plant for any cold-hardy citrus collection.

Trees are grafted with mature, certified buds, so they will fruit quicker.

Please keep in mind that we are unable to ship any citrus to AZ, CA, HI, FL, LA, TX.  These restrictions are due to USDA Agricultural laws. We do ship growing supplies such as potting mix, fertilizer and non citrus material items to AZ, FL, LA, and TX.

  • We ship via UPS Ground
  • We ship Mondays & Tuesday mornings.
  • If your order is placed after 9am on Tuesday it will likely ship the next week.
  • Trees may need to be topped or pruned to fit in the box.
  • Tracking number will be emailed to you when your order ships, please check your spam folder if you don't see an email.

These are a few questions we are often asked and their answers:

  • Why dont you ship to FL or CA?
    We aren't able to due to USDA restrictions, we wish we could but we can't.
  • When will my tree fruit?
    We graft with certified mature buds so our trees are capable of flowering and producing fruit in the first season, but will definitely flower and produce fruit in the second season. We recommend removing fruit for the first couple years to allow the tree to focus on branching and growing roots.
  • What does this variety taste like?
    In most cases the original Budwood program we purchased Certified buds from does not offer much in the way of descriptions or taste information. We then grow those buds out and continuously harvest new buds and then sell young trees so we simply don't always end up with fruit to try so unless its listed, we don't know what they taste like.
  • Do you have anymore of these available?
    We try hard to add inventory when it grows large enough, if a product shows as 0 available please click the notify button to be emailed as soon as we add inventory to the site.
  • What rootstock is this grafted onto?
    We use a handful of rootstock varieties for different reasons when we are grafted. If the variety says "Dwarf" then that variety is grafted to Flying Dragon. If it is not listed as Dwarf then we either used a standard rootstock or semi dwarfing rootstock. When fully mature the difference between Dwarf and Standard is only about 80% difference, it just takes dwarf longer to grow that large. You can maintain tree size through pot size and effective pruning.
