Scarlet firethorn (Pyracantha coccinea) is one of three species of Pyracantha included on the Cal-IPC Inventory of invasive plants. They are evergreen shrubs in the rose family with green leaves and bright red berries. The fruits are widely dispersed by birds, which may also nest in the bushes. Their spread is more likely in warm and moist habitats.
P. crenulata and P. coccinea are considered "waifs" which are plants that have not persistently been able to survive and reproduce over time without human help where they are not native. P. angustifolia is more widespread and has naturalized in California. All three are included on our list of Plants to Watch. See CalWeedMapper for occurrences in California outside of cultivation.
Why is this plant not included on the invasive plant list?
Pyracantha was initially considered in 2006 and considered again in 2016. They were not added to the nursery survey because the impact and risk from these plants is too low, and because they are a widespread and important ornamental plant.
