The UF/IFAS Assessment of Non-native Plants in Florida's Natural Areas has predicted Pyracantha coccinea to be invasive and the plant is no longer recommended by IFAS.
Firethorn (Pyracantha coccinea) is an evergreen shrub known for the colorful berries it produces in cooler weather. Not only are they attractive, the berries also serve as an important food source for wildlife. The branches hold up well in cut arrangements and make a festive accent in holiday centerpieces.
Firethorn, also commonly called pyracantha, adds visual interest to your landscape throughout much of the year. In spring, it produces many clusters of small white flowers, followed by a huge fall/winter crop of red, orange, or yellow berries which are consumed by resident and migrating birds alike.
This thorny shrub has a number of uses in your landscape. It can be trained as an espalier against a wall, allowed to sprawl unpruned down a slope, or even shaped into a topiary. You can also use its thorns to your advantage by planting it as a barrier.
