Cotoneaster
By Innovation Grounds
Cotoneaster is a genus of deciduous and evergreen shrubs that are popular for landscaping, particularly in gardens and as ground covers. They are known for their attractive foliage, small flowers, and colorful berries.
General Information
- Botanical Name: Cotoneaster spp.
- Family: Rosaceae (Rose family)
- Common Names: Cotoneaster, Rock Cotoneaster, Cranberry Cotoneaster.
- Type: Shrubs, some varieties are ground covers, others are small trees or hedges.
- Hardiness Zones: Generally hardy from USDA zones 4-7, though some species can tolerate zones 3-8 depending on the variety.
- Height: Ranges from 6 inches (for ground covers) to up to 10 feet tall (for shrubs or small trees).
- Spread: Typically 3-10 feet, depending on the type.
Planting and Care
- Soil: Prefers well-draining, moderately fertile soil, but is tolerant of poor soil conditions. A slightly acidic to neutral pH is best.
- Light: Full sun to partial shade. They tend to flower and fruit best in full sun, but they can tolerate some shade, though flowering may be less abundant.
- Watering: Regular watering is needed for establishment, but once established, Cotoneasters are fairly drought-tolerant. They do not like wet, soggy soil, so ensure good drainage.
- Fertilizing: Apply a balanced fertilizer in spring to promote healthy growth. Over-fertilizing can lead to excessive growth at the expense of flowers and berries.
- Pruning: Prune in late winter or early spring before new growth begins. Remove any dead, diseased, or damaged branches, and cut back old wood to encourage new growth. Some varieties can be used as hedges and tolerate more regular pruning.
Varieties and Uses
- Groundcovers: Some Cotoneasters, like Cotoneaster horizontalis (rock cotoneaster), are popular as groundcovers, with their low-spreading growth and red berries in fall.
- Hedges and Borders: Varieties such as Cotoneaster lacteus (smooth cotoneaster) make excellent hedges, as they can be pruned into neat shapes.
- Specimen Shrubs: Cotoneaster acutifolius (sharp-leaf cotoneaster) can be used as a specimen shrub due to its upright growth habit and attractive fall berries.
- Landscape: Cotoneaster species are often used in rock gardens, along slopes, or as accent plants.
