Growing Mock Orange Shrubs: Planting, Caring, & Pruning Tips
Mock orange shrubs (Philadelphus spp.) are cherished for their lush, citrus-scented blossoms and enduring presence in cottage gardens. Recent breeding efforts have introduced compact, more ornamental varieties, ensuring that these classic shrubs remain relevant and beloved in modern landscapes. This guide covers everything you need to know to plant, grow, and care for mock orange shrubs, enabling you to enjoy their heady fragrance and visual charm each spring.
What Is Mock Orange?
Mock orange refers collectively to a group of deciduous shrubs in the genus Philadelphus, named for their distinctive, white, often double flowers that exude a sweet fragrance reminiscent of orange blossoms. Despite their common name, mock oranges are not related to true citrus but are instead valued for their ornamental qualities and versatility in the garden.
- Botanical Name: Philadelphus spp.
- Common Names: Mock orange, English dogwood
- Zones: 4â8 (see hardiness and climate)
- Height/Spread: 4â8 feet tall and wide (varies by cultivar)
- Flower Color: White, sometimes with yellow stamens
- Foliage: Medium to dark green, ovate leaves; deciduous
- Bloom Time: Late spring to early summer
- Fragrance: Sweet, orange blossom-like scent
Main Features & Benefits
- Intensely fragrant clusters of white blooms
- Attractive, upright form for hedges or specimen plantings
- Easy maintenance and few serious pest or disease issues
- Newer cultivars offer compact size, repeat blooming, or improved flower forms
Where to Plant Mock Orange
Choosing the right spot is crucial to maximize the appealâand the legendary scentâof mock orange shrubs. Ideal planting locations include:
- Near patios, walkways, or entryways where the fragrance can be enjoyed
- Along the back of mixed borders for height and seasonal interest
- In groups to form a loose privacy hedge or screen
- As single specimen plants in lawn or cottage garden settings
These shrubs thrive in full sun to partial shade but produce the most abundant flowers when they receive at least six hours of direct sunlight daily.
Ideal Soil and Site Conditions
- Fertile, well-drained soil is best; avoid heavy, waterlogged sites
- pH should be neutral to slightly acidic
- Top-dress new plantings with compost or well-rotted manure for extra nutrients
- Avoid deep shade, which reduces flowering
How to Plant Mock Orange Shrubs
Plant mock orange shrubs in spring or early fall to give roots time to establish before flowering. Follow these steps:
- Dig a hole twice as wide as the root ball and just as deep
- Add compost or organic matter to enrich the soil
- Tease out roots if pot-bound and place the shrub at the same level it grew in the pot
- Backfill, firming the soil gently, and water in thoroughly
- Mulch to retain moisture and suppress weeds

Space multiple plants 4â8 feet apart according to mature size.
Mock Orange Shrub Maintenance and Care
- Water: Keep soil moist but not soggy, especially during the first two years after planting. Mature plants tolerate short dry spells.
- Fertilizer: Generally, mock oranges are light feeders. Apply an all-purpose, water-soluble fertilizer in late winter or early spring if growth appears weak.
- Mulch: Mulch annually with compost or organic matter to retain soil moisture and boost fertility.
- Pruning: Prune after flowering, removing spent blooms and up to a third of old stems to encourage new, flower-bearing growth. Avoid pruning in fall, as this removes buds for next year.
- Sunlight: Provide at least 4â6 hours of sun for optimal flowering.
Common Problems, Pests, and Solutions
Mock orange shrubs are notably low-maintenance and resistant to most pests and diseases, making them a sound choice for both experienced and novice gardeners.
- Pests: Aphids may occasionally appear but are rarely serious. Rinsing with water or applying insecticidal soap typically resolves infestations.
- Diseases: Rarely affected, but good air circulation and well-drained soil prevent most potential issues.
- Poor Flowering: Usually a result of insufficient sunlight or pruning at the wrong time.
- Leaf Discoloration: May be caused by soggy soils; improve drainage and avoid overwatering.
Popular Mock Orange Varieties
Plant breeders have introduced several cultivars with improved size, flower form, and repeat-blooming potential. Here are some popular types:
| Variety | Height | Flowering Features | Notes |
|---|---|---|---|
| Philadelphus coronarius | 8â10 feet | Single, highly fragrant blooms | Classic species; vigorous and reliable |
| ‘Belle Etoile’ | 4â6 feet | Single, white blooms with purple centers | Compact, strong scent |
| ‘Virginal’ | 6â10 feet | Double, large flowers | Dense growth, ideal for screens |
| ‘Snowbelle’ | 3â4 feet | Double, creamy-white blooms | Dwarf, good for containers |
| ‘Miniature Snowflake’ | 2â3 feet | Double, small white blooms | Perfect for small spaces |
Design Tips and Uses in the Landscape
- Hedges and Screens: Use taller types for informal privacy hedges
- Background Shrub: Place at the rear of perennial borders or mixed shrub beds for backdrop and seasonal height
- Specimen Plant: Mass plant compact cultivars nearer to walkways and entryways
- Cut Flowers: Enjoy their citrus fragrance indoors; remove foliage for a cleaner display
Combine mock orange with spring bulbs, peonies, or other late-spring bloomers for a succession of color and interest.
Propagation
Mock orange can be propagated from softwood or hardwood cuttings:
- Softwood Cuttings: Take 4â6 inch cuttings in late spring, remove lower leaves, and root in moist, well-drained potting mix
- Hardwood Cuttings: Collect pencil-thick stems in late fall or winter, insert into sand or soil, and keep cool until spring leaf-out
Seed propagation is possible but rarely used due to variable offspring. Named cultivars should be propagated by cuttings for true-to-type plants.
Seasonal Care Calendar
- Winter: Apply mulch before hard freezes; minimal care needed
- Early Spring: Fertilize lightly if necessary; check for winter damage
- Late Spring: Enjoy the blooms; water regularly in dry spells
- Early Summer: Prune immediately after flowers fade; remove dead or crossing stems
- Autumn: Prepare new planting sites; propagate by hardwood cuttings
Frequently Asked Questions (FAQs)
How long does mock orange bloom?
Most varieties bloom for one to two weeks in late spring or early summer, with the exact timing depending on local conditions and variety.
Is mock orange deer resistant?
Mock orange is often listed as deer-resistant; however, browsing behavior can vary by region and availability of other food sources.
How do I get more flowers?
Ensure your shrub receives ample sunlight, avoid excessive nitrogen fertilizer, and prune immediately after flowering to preserve next yearâs buds.
Can mock orange grow in containers?
Yes, dwarf varieties like ‘Miniature Snowflake’ or ‘Snowbelle’ can be grown in large pots with well-draining soil and regular watering.
When is the best time to prune?
Prune immediately after flowering, before new flower buds are set for the following year. Hard pruning in autumn or winter will remove potential blooms.
Conclusion
Mock orange shrubs stand as a testament to the enduring appeal of classic garden plants, bringing together exquisite fragrance, easy care, and reliable performance. Whether you remember them from a grandparentâs old-fashioned garden or are just discovering new cultivars, mock oranges are worthy additions to nearly any landscape.
