I’m sorry to say that I am not sure what the exact type is, but I’m thinking it is a Meyer. I purchase one of those two in one lemons and limes from burgess.
When the lime part had thorns, I just kept whacking it off and not letting it grow, so now it’s just a lemon tree. The skins is thinner than grocery store lemons and the shape is round and it’s a bit sweeter too.
thanks I’ll look into that.
