The ponderosa lemon (Citrus × pyriformis) (also called Skierniewice lemon[1]) is a citrus hybrid of a pomelo and a citron. It is not the same as the 'Yuma Ponderosa' lemon-pomelo hybrid used as citrus rootstock.[2]

Ponderosa lemon trees are slow growing but reach a height of 12 to 24 feet (3.7 to 7.3 m) at maturity. The leaves are long, evergreen, glossy, and citron-like, being ovate elliptic in shape and lemon scented.[3] They have medium-thick branches with many spines. New growth is purple-tinged, as are the flowers.[4] Ponderosa lemon also has larger than average citrus flowers, and bears fruit throughout the year. When grown as an ornamental, it requires pruning to control the shape, and may be trained as a bush or tree.

Ponderosa lemon is less cold-hardy than a true lemon.[5] It bears medium to large fruit with a thick and bumpy rind. The fruits are seedy, and while they look similar to a citron, they taste like a lemon.

Origin

The ponderosa lemon originated in roughly 1887, and is believed to come from a chance seedling grown in Hagerstown, Maryland. It was later named and introduced to the nursery trade in 1900.[3] 

Though often referred to as a cross between the lemon and citron, a recent genomic analysis showed it to solely contain pomelo (Citrus maxima) and citron (Citrus medica) DNA, perhaps being an F2 hybrid.[7] Thus they cannot derive from true lemons, which have a mandarin orange component.

Uses

While the fruit are larger than that of a normal lemon, they have the same flavor and acidity. As such, the fruit can be used in place of true lemons. There is enough juice for several lemon pies in just one large Ponderosa lemon, and they can replace lemons measure for measure in recipes.[9]

The fruits last extremely well on the plant, and may be allowed to remain on it for months without danger of deterioration.
