Pyracantha ‘Mohave’ short overview
Pyracantha 'Mohave' is a vigorous, thorny evergreen firethorn valued for glossy dark-green foliage, abundant white flower clusters, and heavy crops of orange-red berries that can remain attractive into winter. Developed through the U.S. National Arboretum’s plant-introduction program, this upright shrub is useful for sunny hedges, screens, barriers, and specimen plantings. Give it well-drained soil, room for its spines, and prune after flowering to preserve next year’s bloom.
Taxonomic classification
Pyracantha ‘Mohave’ care guide
Light and placement
Best flowering and fruiting occur in full sun, with at least 6 hours of direct light. Partial shade is tolerated, especially in hot climates, but dense shade can reduce flowering, fruiting, and compact growth. A sunny east-, south-, or west-facing position is suitable; provide airflow and avoid cramped corners. Pale, sparse growth suggests insufficient light, while winter leaf scorch may indicate intense exposure combined with drying winds.
Watering and humidity
Water deeply and thoroughly when the upper few inches of soil begin to dry, rather than giving frequent shallow sprinklings. Keep newly planted shrubs consistently moist during establishment, then reduce irrigation as roots mature. Established plants tolerate short dry periods but fruiting and foliage suffer under prolonged drought. Avoid saturated soil and wetting the canopy late in the day.
Soil and growing medium
Use moderately fertile, well-drained soil with good air movement around the roots. ‘Mohave’ tolerates sand, loam, and clay and adapts across a broad pH range, from slightly acidic through neutral to mildly alkaline. Avoid persistently waterlogged ground; improve heavy soil with organic matter and plant slightly high if drainage is marginal.
Feeding
Apply compost or a balanced slow-release shrub fertilizer in early spring as growth begins, following the product label. Avoid heavy nitrogen feeding, which can produce soft, overly vigorous shoots and reduce the balance between flowering and fruiting. Do not fertilize drought-stressed, newly transplanted, or visibly diseased plants until they have recovered.
Growth and habit
This is a vigorous, dense, upright shrub with stiff, thorn-bearing branches. It can become a substantial hedge or screen and responds well to training and renewal pruning. Because flowers form on older wood, maintenance should preserve short flowering spurs rather than shearing indiscriminately before bloom.
Planting and repotting
Plant in spring or fall while temperatures are moderate. Set the root ball level with the surrounding soil, or slightly high in heavy ground, then water deeply to settle the roots. Space plants about 6–10 feet apart for a hedge, depending on the desired density and pruning regime. Mulch lightly, keeping mulch away from the trunk, and irrigate regularly during the first growing season.
Container plants should be shifted into the next larger pot when roots fill the container, preferably in early spring before strong growth begins. Use a durable, free-draining potting mix and a heavy container that will not tip as the shrub enlarges. Handle branches with thick gloves because the spines are substantial.
Propagation and pruning
Propagation
Propagate commercially or experimentally from softwood, semi-hardwood, or hardwood cuttings taken during the active growing season or dormant season, using clean material and a well-drained rooting medium. Cultivar traits are preserved by vegetative propagation; seedlings will not reliably reproduce ‘Mohave’.
Pruning
Prune after flowering, usually in early to mid-summer, because next season’s flowers develop on older wood. Remove dead, damaged, crossing, or excessively crowded branches first, then shorten selected shoots to control size and shape. Use long sleeves, thick gloves, eye protection, and bypass pruners; avoid severe pre-bloom shearing if flowers and berries are priorities.
Overwintering
Plants in Zones 6–8 generally overwinter outdoors without special protection once established. Water before the ground freezes if autumn is dry, and apply a light mulch over the root zone without touching the stems. In exposed northern sites, protect young shrubs from drying winter winds with temporary screening. Container plants have less root insulation and should be sheltered in a protected, unheated location during severe freezes.
Uses
Use ‘Mohave’ as a thorny hedge, privacy screen, security barrier, espalier, foundation accent, or specimen shrub. Its evergreen foliage and persistent orange-red fruit provide multi-season structure. Avoid planting beside paths, play areas, or seating where the spines may contact people or pets. The berries should not be promoted as edible.
Appearance
‘Mohave’ forms a dense shrub with upright to arching, thorn-bearing branches and rough brown bark. The simple leaves are narrow to oval, glossy, leathery, and dark green. Small white flower clusters give way to conspicuous orange-red pomes. The persistent fruit and evergreen foliage provide strong seasonal identification, while the sharp spines distinguish it from many similar berrying shrubs.
Flowering
Small white flowers are borne in conspicuous clusters on older wood in late spring to early summer, commonly around May and June in much of the United States. Flowering is followed by heavy crops of orange-red pomes. Pruning immediately before bloom can remove the shoots that carry the next display.
Pollination and visitors
The small, open white flowers fit a generalist insect-pollination pattern and provide pollen, with limited nectar. Extension sources specifically record bees and pollinators visiting Pyracantha flowers. Evidence for a particular bee species visiting this exact cultivar is not sufficiently specific for a Latin species name.

Diseases and pests
Diseases
‘Mohave’ is recognized for good resistance to fire blight and scab, although no cultivar is completely disease-proof. Reduce risk with full sun, adequate spacing, clean pruning tools, and irrigation directed at the soil rather than the foliage. Remove badly infected shoots during dry weather and avoid excessive nitrogen, which encourages soft growth.
Pests
Watch for aphids, scale insects, spider mites, and lace bugs, especially on stressed or densely planted shrubs. Inspect new growth and the undersides of leaves. Improve vigor with correct watering and pruning for airflow; use a strong water spray for light infestations, and reserve labeled horticultural oils or insecticides for persistent problems, following all product directions.

Toxicity and pollen
Available poison-control evidence indicates Pyracantha berries are not considered poisonous to people or animals, although eating large quantities may cause mild stomach upset. The principal practical hazards are thorn punctures and choking in young children. Do not treat the berries as food, and wear thick gloves and eye protection when pruning.
- Typical season
- May–June in much of the United States
- Pollination / pollen
- Heavy, insect-carried pollen
‘Mohave’ is insect-pollinated, so its pollen is generally heavier and less readily dispersed through the air than pollen from wind-pollinated trees and grasses. This supports a low airborne-allergy classification, not a claim of zero risk. Sensitive people may still react during flowering or through close contact with flowers.
Native habitat
The cultivar is a cultivated hybrid rather than a wild habitat plant. Its Pyracantha background is associated with temperate regions of Europe and Asia. In gardens it performs in sunny, moderately dry to moist sites, including urban conditions, provided the soil drains well and roots are not kept saturated.
Interesting fact
‘Mohave’ was introduced by the U.S. National Arboretum and became a widely grown hybrid firethorn. Its abundant fruit display can be more ornamental than valuable to birds, because the cultivar is reported to have relatively low bird appeal. The name firethorn reflects the combination of bright fruit and sharp spines.
