I grow Citrus trees from seed all the time. I even have some Meyer seedlings at the moment. Realize that any plant from seed may not come up true to form. Citrus trees take 5-10 years before they will flower (an educated guess based on my experience.) But they do make nice houseplants. I have one student who comes over once in a while. She is from Viet Nam and always picks off a few leaves and eats them. They use them in salads. Gene
