Inherited from plant definition
Quick summary
- Water
- Moderate; keep evenly moist, not soggy
- Light
- Full sun for best bloom
- Toxicity
- Caution: can upset pets if eaten
- Care notes
- Plant in full sun, well-drained slightly alkaline soil; prune right after bloom and water deeply during dry spells.
Watering
- Cadence
- Deeply once weekly in dry weather; less for established plants
- Moisture level
- Evenly moist at the root zone; dry slightly between waterings
- Drought tolerance
- Moderate to good once established
- Wet/dry cycle notes
- Water at the base; avoid frequent shallow watering
- Seasonal adjustments
- Increase during spring establishment and summer heat; reduce in cool, wet periods and in winter dormancy
Light
- Intensity
- Full sun
- Duration
- At least 6 hours direct sun daily; 8+ hours preferred
Temperature and hardiness
- USDA zone
- USDA zones 3–7, sometimes 8 with good siting
- Cold tolerance
- Hardy to severe winter cold when dormant; flower buds may be damaged by late freezes
- Heat tolerance
- Moderate; struggles in prolonged hot, humid summers
- Frost sensitivity
- New growth and buds are sensitive to late spring frost
- Overwinter instructions
- No special protection needed in-ground in suitable zones; mulch roots lightly and avoid winter pruning
Humidity
- Range
- Average outdoor humidity; prefers dry to moderately humid air
- Dry air tolerance
- Good
- Misting notes
- Misting not needed and may encourage disease
Soil and medium
- Preferred medium
- Fertile, loamy, well-drained soil
- pH preference
- Slightly alkaline to neutral, about pH 6.5–7.5
- Drainage needs
- Excellent drainage required
- Growth substrate habit
- Shrub or small tree; strong woody root system
- Substrate recipe notes
- Amend heavy clay with organic matter and ensure drainage; avoid waterlogged sites
Fertilization
- Type
- Balanced slow-release fertilizer or compost
- Strength
- Light to moderate; avoid excess nitrogen
- Frequency
- Once in early spring, or top-dress annually with compost
- Seasonal schedule
- Feed in early spring only; avoid late-summer or fall fertilization
- Micronutrient notes
- If chlorosis occurs, check pH and iron availability in high-alkaline soils
Repotting
- Interval
- Rarely repotted; plant out or shift to a larger container only as needed every 2–4 years
- Pot type
- Large, heavy container with broad drainage holes
- Root sensitivity
- Moderately sensitive to root disturbance; handle minimally
- Dormancy consideration
- Best moved or transplanted in late fall or very early spring while dormant
- Division guidance
- Not usually divided; propagate by cuttings, layering, or suckers instead
Propagation
- Preferred methods
- Softwood or semi-hardwood cuttings, layering, suckers, grafting, seed
- Difficulty
- Moderate
- Expected success
- Cuttings and layering are usually reliable; seed is slower and variable
- Optimal timing
- Late spring to midsummer for cuttings; autumn or early spring for layering and transplanting suckers
- Rooting hormone notes
- Bottom heat and rooting hormone improve cutting success
- Tissue culture notes
- Possible in specialized production, but not typical for home or collection use
Pests and disease
- Common pests
- Aphids, scale, borers, leaf miners, mites
- Common diseases
- Powdery mildew, leaf spot, bacterial blight, verticillium wilt, canker
- Treatment notes
- Prune out dead wood, improve airflow, avoid overhead watering, and treat pests early with cultural controls or targeted sprays if needed
- Susceptibility level
- Moderate; generally hardy but prone to mildew and poor-bloom issues in shade
- Preventative practices
- Full sun, good air circulation, well-drained soil, timely after-bloom pruning, and clean pruning tools
Toxicity
- Pets
- Generally considered mildly toxic if ingested; may cause gastrointestinal upset
- Humans
- Generally low hazard, but ingestion may cause stomach upset
- Sap irritant
- Usually not a major skin irritant; sensitive individuals may react
- Edible?
- Not considered edible; flowers are sometimes used decoratively but ingestion is not advised
Dormancy and blooms
- Dormancy behavior
- Deciduous and winter-dormant; buds set on old wood
- Typical bloom season
- Late spring
- Bloom duration
- About 2–4 weeks, depending on weather and cultivar
- Fragrance
- Strongly fragrant
- Rebloom tendency
- Usually once-blooming; some cultivars may give light rebloom
- Bloom triggers
- Cool winter chilling, full sun, and mature wood; poor bloom with excess shade or nitrogen
- Pollinator notes
- Attracts bees and other pollinators
Growth habit
- Growth habit
- Multi-stemmed deciduous shrub or small tree with opposite leaves and terminal flower panicles
Conservation and collection status
- Rarity
- Common in cultivation
- Conservation status
- Not generally listed as threatened; conservation concern usually low in cultivation

- Protected species notes
- Typically not protected; verify local regulations for wild collection
- Collection restrictions
- Check phytosanitary rules for live plant movement and nursery stock import requirements
- Import/export concerns
