Narrowleaf firethorn

Pyracantha angustifolia is a shrub in the rose family (Rosaceae) with narrow leaves and sharp spines. It bears white flowers that develop into small, round pomes, typically orange to red in color. These fruits are bitter and inedible for humans but serve as a food source for birds. The plant's leaves, fruit, and seeds contain hydrogen cyanide, contributing to its bitter taste. Cultivated as an ornamental, it is used in landscaping for hedges and security. Native to China, it has been introduced to regions including North America, Australia, and parts of Africa and South America. It is considered invasive in Hawaii and other locations. The species was first described in 1906 and is found in a wide range of protected and global areas.
