I had my first moro blood orange today and I must say it tastes better than I thought, I was imagining a not pleasent taste. To me it taste similar to navel. Anyways I got a seed out of it and was wondering does it come true I imagine so if not I will plant it anyways and see what happens.

I recently asked the same question-- Millet says yes-- but count on 10 yrs for fruit.

MMm oh well I will plant it anyways and now that you mention I remember seeing that thread sorry for posting a repeat.

Valenciaguy, for the Moro seed = from seed to fruit is approximately 10 - 12 years when grown outside in a warm location such as Florida, or southern California. When grown as a containerized tree outdoors during Canadian summers for 4/5 months, then indoors for the balance of the year, it could take 15-18+ years to bloom/fruit. By then, if or when, you can get the tree to fruit, the tree would have long passed been much to large to fit in your living room. - Millet

are some cultivars just like that? because you said about oranges and lemons they can fruit within 5-6 year but grapefruit and moro can't? Also after a certian point,(I know it wouldn't speed up the time to fruiting) but couldn't i graft it onto a FD seedling that i am curently growing just to keep it on the smaller size.

Valenciaguy, your correct, different citrus cultivars require different amounts of time to mature. Not only Moro Blood Orange, but all Orange cultivars require 8- 10 years to mature when grown outside in warm locations. Yes, you could keep the tree small by various methods, however, then the tree would never fruit. Seedling oranges mature ONLY after the tree has produce the required node count (which is a very large number). If you artificially keep the tree small, it will never grow enough to obtain the required number of nodes. - Millet

I have also noticed that there is more pigment in one end of the orange than the other why is this?
