Sometimes called Chinese oranges, these are the smallest and weirdest of the common citrus fruits and in a contrary turnaround from others from this group, the skin and zest are sweet, while the juicy insides are just not as sweet as many oranges, but not really sour. The size of very small plums, they are often used as an expensive winter treat and can be eaten whole, just as they are,(yes really, I have tried them), or cooked with sugar, spices or spirits to make sweet comp?tes and aromatic chutneys. They grow true from the seeds but very few fruits actually contain good seeds, if any at all. SOWING ADVICE: These seeds have already been thoroughly cleaned and should be sown into a well-drained, sandy compost at any time of the year, and covered thinly with sand or grit and kept moist. Keep at between 20-25 degrees C. Seeds sometimes germinate within 4 to 6 weeks although some varieties may take very much longer so please be patient. Plant out in the open ground in warmer countries or in a large container elsewhere.
