Southern paper almonds are fresh seeds of the Prunus dulcis tree, a nut-bearing shrub or small tree from the subgenus Almond (Amygdalus) of the genus Plum. This variety is resistant to spring frosts and boasts a higher kernel to shell ratio than other almond varieties.
Prunus dulcis reaches a height of 4-5 m, with a very hilly surface. The pubescence is short and velvety, and the pericarp pulp is very hard and dry. The flowers are white, with crimson edges on the petals, measuring 3 cm in diameter. The fruits are large, 4 cm long, with a papery shell. The kernels are light brown, rough, less often wrinkled or smooth, and taste sweet.
Prunus dulcis is native to the Mediterranean region, typically growing in areas with mild winters and hot, dry summers. It thrives in regions with a USDA Hardiness Zone of 5 or higher.
Southern paper almonds are one of the sweetest and most delicious types of nuts. They require cross-pollination, preferably with other varieties, and begin to bear fruit in 4-5 years. This variety is known for its high kernel to shell ratio and thin shell, making it a popular choice among nut enthusiasts.
Prunus dulcis prefers well-draining soil and full sun to partial shade. Regular watering and fertilization are essential for optimal growth. Prune the tree annually to maintain its shape and promote fruiting.
The fruits are ready to harvest in late summer to early fall, when the papery shell turns brown and the kernel is mature. Gently shake the tree to release the nuts, and then collect them from the ground.
Prunus dulcis can be propagated through seed or grafting. Seed propagation is more challenging, as it requires cross-pollination and a longer germination period. Grafting is a more reliable method, as it allows for the transfer of desirable traits from a mature tree.
