General
Mock orange is a classic deciduous flowering shrub valued for its intense, sweet fragrance and abundant white blossoms in early summer. It is very hardy, easy to grow, and long-lived, making it a staple in traditional gardens as well as modern landscapes. Growth is upright to arching, and older plants can become quite large if left unpruned. There are also smaller-growing cultivars available that are well suited to compact gardens and urban settings.
Light
Full sun to partial sun; best flowering in full sun.
Soil type
Normal garden soil; prefers well-drained loam but is adaptable to most soils.
Water requirement
Medium; water during prolonged dry periods, especially when newly planted.
Nutrient requirement
Low to medium; excessive fertilization reduces flowering.
Precultivation
Mock orange is usually propagated by cuttings or purchased as container-grown plants. Seed propagation is uncommon and mainly used in breeding, as seedlings vary in growth and flowering.
Planting
Plant in spring or early autumn when soil moisture is reliable. Choose a sunny or lightly shaded site with enough space for the mature size. Dig a generous planting hole and loosen the surrounding soil to encourage root establishment. Water well during the first growing season.
Pruning
Flowering occurs on older wood, so pruning should be done immediately after bloom. Remove up to one third of the oldest stems at ground level to rejuvenate the shrub. Avoid heavy pruning in autumn or spring, as it reduces flowering.
Maintenance
Mock orange requires minimal care once established. Mulch in spring with compost to improve soil structure. Water during extended droughts. Fertilize lightly if growth is weak, but avoid high nitrogen levels.
Harvest
Not applicable, as this shrub is grown for ornamental value rather than harvest.
Common issues
Generally problem-free. Aphids may appear on young shoots. Poor flowering is usually due to lack of sun or incorrect pruning timing.
Pollination
Insect-pollinated, mainly by bees.
Companion plants
Lilac, spirea, weigela, perennial geraniums.
Incompatible plants
Plants that require constantly wet or very acidic soil.
