About Pyracantha angustifolia (Franch.) C.K.Schneid.
Pyracantha angustifolia (Franch.) C.K.Schneid. is a species of shrub in the rose family, commonly known as narrowleaf firethorn, slender firethorn, and woolly firethorn. It produces white flowers that develop into small, round pomes, which range in color from orange to red. These fruits are astringent and bitter, making them inedible for humans, but they serve as a food source for birds. The leaves, fruit, and seeds of this plant contain hydrogen cyanide, which causes the fruit's bitter taste. The stems and branches are lined with sharp spines. This shrub is cultivated for planting in yards and gardens as an ornamental plant, and it can be grown into hedges for home security. Native to China, the species has been introduced to North America and Australia, and it is classified as an invasive species in Hawaii and other areas.
