Here is a picture of a bloom on a marmaladequat seedling. I let a branch grow on my sunquat/mandarin tree. One branch is plenty for marmaladequat as they are kumquats the size of mandarins but with little flavor and not too tasty. The seed for the tree came from Stewart Nagle at a master gardener's sale where he was selling his book before he died. He called it marmaladequat. I've seen sunquat and his mandarinquat is the same thing.
This tree took only 2 years to fruit from seed in the ground. After it fruited, I decided marmaladequat was not very good so I made it into a changshou and meiwa kumquat. That was 10 or so years ago. Last year I had 20 gallons or more of changshou fruit so I topworked it to sunburst, fallglo and lee x orlando 15-150 mandarins. I left enough of it for kumquats without throwing away most of the fruit. I now have a 6 in one tree. Last year I made 50 pints of marmalade and still had too much fruit.
