I have a Sweet Lemon tree. It produces fruit with the same general size and appearance as an Eureka lemon. The rind gives off a very strong lemon scent when scratched, and the pulp looks just like most any lemon. The tree is blooming and the flowers are pure white, not a hint of pink/purple. The new foliage growth is green, without any purplish tint. Therefore, I don't know whether it has any actual lemon parentage or not. In my opinion the tree is probably not worth growing. The pulp is rather bland/insipid without much taste of any kind. I was not going to bother growing it, and had stopped watering it. Luckily for the tree, I never got around to tossing it onto the compost pile. A couple weeks ago I noticed it had deteriorated to a pathetic condition, and I felt sorry for the poor thing. Relenting, I started watering it. Now it is in full bloom and putting on a lot of new foliage. Still in my opinion I don't think Sweet lemon is worth the bother. Visitors seem amazed when they eat one thinking it to be sour, and finding that the fruit does not produce any acid. The tree is now moved into Limbo, as what its future will be. Probably I will just give it away to some visitor who comes along that will want it and take care of it. Still I wonder what is its parentage. - Millet (639-)

I need to be your neighbor, I would take a lot of your throw aways. Why not top work it into another variety or something?

I tried a store bought sweet lemon and was quite disgusted by the taste.

So do you folks like Sanbo lemon?

Yes Ned gave us a few 2 years ago and it suddenly became my favorite citrus of all. I wont tell you how many I have growing right now but I do like it. Sanbokan Grapefruit is how I have them taged.

Yes, Sanbokan Lemon/Grapefruit are great tasting. Some retailers sell them as Sanbokan Lemons, and others market them as Sanbokan Grapefruit. I guess one can call them what they want. I have two Sanbokan trees, one growing in the ground. plus a container grown tree. - Millet (638-)

Millet, man after my own heart I have what I think is a Palestine Lime. I have to cut into one of the fruits to check. If it's insipid, it is. Should I cut it down? Probably. But, I rescued it, along with about 4 or 5 other citrus that were just in terrible shape, so now, how can I possibly do this to this poor wee little tree?? Sigh... I could use the space to put in something else, but I just cannot bring myself to do it. It should have died, and now it's just thriving. Same thing - solid white flowers, no pink anywhere on the flower or flush, but most obviously some sort of lemon or lime. The previous owners could not remember, and the tag is long gone. In fact, it must have had a thin metal stake, as there is this odd metal thing sticking out of the ground, and I think the poor tree grew around it, I can't yank it out. Ugh, what to do, what to do!

I have a sweet lemon too, called Pomona or Ponoma, I always forget which it is, but I think it's Pomona. It's so odd not to have that tart lemon taste, the brain tells you something is wrong!
I still use the fruit, but I mix the juice of the sweet with the juice of a tart one and it works out fine that way.
