All about Kumquats

You may have seen these small, oblong, rather mysterious orange fruits at your grocery store or farmers market. Did you know…

  • Kumquats are a citrus fruit. In fact, they are the smallest citrus fruit. (UF/IFAS Plant Identification Learning Module 2009).
  • Kumquats are the only citrus fruit that can be eaten whole—no peeling required! The inside of the fruit is tart, while the outside is sweet (FDACS 2015).
  • Kumquats are an excellent source of fiber (Percival and Findley 2014).
  • Most Florida kumquats are grown in Pasco County (FDACS 2015).
  • Kumquats originated in eastern Asia (Encylopaedia Britannica Online 2015). Kumquats grown in Florida are considered a very sustainable crop (Andersen, Williamson, and Olmstead 2012).

    The ones I am eating today are from Alachua County and they are delicious. If I plant the seeds, will I get perfect kumquats again or I wonder if I will get part of a hybrid or rootstock.

      Julieta, this is the answer to your question from Dr. Jonathan Crane, a UF/IFAS Extension Topical Fruit Crop Specialist:

      “1.Propagation of kumquat by seed may or may not result in the same identical plant. Kumquats can produce seed from nucellar (mother plant) tissue and through cross pollination with other citrus.
      2.Propagation by seed usually results in weak plants.
      3.Kumquat is mostly propagated by grafting or budding onto cold hardy rootstocks (usually trifoliate orange, ‘Flying Dragon’).”
