I thought some might be interested in this 1994 article. I knew two of the finders, Stewart Nagle and Louis Waldon. That is Louis on the cover of Fruit Gardener magazine. I think the fruit is marginal, perhaps good for a fruit collector to eat one or two a year which is all I want to eat. The fruit in the picture is on the small side. I get fruits that average 2-3 inches in length. I got my sunquat seeds from Nagal in 2000 when he was alive. He called his marmaladequat. Mine fruited from seed in two years in the ground. Shortly thereafter I topworked the tree to changshou kumquat. A year or two ago I let a branch of sunquat grow and got a dozen or so fruit and sent the seeds out to forum members. Giant kumquat indeed!

I love all kind od Kumquats.

I used to have a Sunquat tree. Unfortunately, it fell into the compost pile and I was not able to get it out. - Millet

Millet, you are more dangerous, than citrus greening. Poor citrus trees.
