I have a collection of citrus trees in my urban orchard – oranges, lemons, cumquats, limes, citrons, lemonade fruit, tangelo and pomelo. A lot of trees in a very small space. It means they constantly cross with each other and produce surprising fruit.
This year the Eureka lemons all want to look like something else. Often the fruit of a cross pollinated citrus have lots of seeds and if I have the energy and the space I would raise some seedlings. However, it would also take more patience than I have because seedlings can take seven years or more to fruit.
