Mohave Pyracantha is a popular cultivar of the firethorn shrub. It's a vigorous, evergreen (or semi-evergreen in colder areas) plant prized for its dense growth, thorny stems, glossy dark green foliage, abundant white spring flowers, and especially its massive displays of bright orange-red to scarlet berries that ripen in fall and often persist through winter. It's a tough, low-maintenance shrub once established — tolerant of wind, some shade, and challenging conditions — and a favorite for adding bold seasonal color without much fuss.
