Rootstock Lemon!

[GilaMonster]

I've mentioned this lumpy lemons in some comments before on here, the rootstock took over (the graft died), resulting in these lumpy lemons!

Skin is soft and peels like a clementine, this year some of the karget I've seen on the tree, the one pictured is not yet ripe and nearly larger than my hand

Look up rough lemon rootstock. I’ve been reading about common root stock for citrus. I’m growing a key lime but it’s been grafted onto what I hope is a rough lemon.
Trifoliata - used for most varieties of citrus and ideal for the home gardener. The rootstock is sometimes called a “semi-dwarfing” rootstock as it will slow down the overall size of the tree when compared with other rootstocks. Trifoliata also has other excellent qualities including being cold and drought tolerant.

Flying Dragon is a specific trifoliate often used as rootstock.

Thanks for responding with some rootstock names, that will make for interesting reading. Inheriting trees makes for an interesting saga
