- Suitable For:
- Is Weed: No
- Allergenicity: moderate
Environmental Needs
- Climate: {"temperatureRange":"–30–40°C"}
- Hardiness: {"zones":"3–8"}
- Misting: rarely required, only if grown in very dry indoor conditions

- Toughness Level: high
- Pruning Frequency: Deadhead flowers as they fade; cut back foliage annually in late fall or early spring.
- Pruning Intensity: Light to moderate; remove only spent flowers and old stems unless rejuvenation is needed.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may produce fewer flowers.
Sunlight Tolerance Tips:
Acclimate plants gradually if moving from shade to sun. Protect from intense midday sun in hot climates. Ensure good air circulation to prevent fungal issues in humid conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Full sun is ideal; avoid deep shade; rotate pots for even growth.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries slightly between waterings; avoid waterlogging.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; amend with compost; avoid heavy clay soils.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C). Hardy in USDA zones 3–7.
Protect from frost; water deeply before cold snaps; avoid sudden temperature shifts.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize sparingly; avoid high-nitrogen formulas; stop feeding in late summer.
Propagation
Methods
Stem cuttings or division of clumps in early spring or fall.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Keep humid.
Best Time: Early spring or fall when temperatures are mild and the plant is not in full bloom.
Environment
Warm, humid conditions (70–75°F or 21–24°C) with indirect light for cuttings.
Medium
Well-draining potting mix with perlite or sand for cuttings; garden soil for division.
Hormone
Optional, but rooting hormone can improve success rates for stem cuttings.
Timeline
Stem cuttings may root in 3–6 weeks; division establishes quickly in the growing season.
Tools Needed
Pruners, rooting hormone, pots, well-draining medium, plastic wrap (for humidity).
Quick Tips
Use sharp, clean tools; maintain humidity for cuttings; divide clumps every 2–3 years.
Pruning & Repotting
Pruning Guide
Method
Use clean, sharp pruners to cut flower stalks just above a leaf node or lateral bud.
Pruning Plan
Remove spent flower stalks to encourage reblooming and maintain plant vigor. Cut back foliage in late fall or early spring to improve air circulation.
Tools
Hand pruners, gloves, clean blades.
Checklist
Deadhead regularly; cut back in fall/spring; sanitize tools between cuts.
Repotting Guide
Best Season
Early spring before new growth begins or fall after flowering ceases.
Pot Size
Increase pot size by 1–2 inches in diameter; avoid oversized pots.
Method
Gently remove the plant, trim any dead roots, and repot in fresh, well-draining soil with a slightly larger container.
Suggestions
Repot only if the plant becomes root-bound or outgrows its container. Division is often preferred over repotting for overcrowded clumps.
Checklist
Check root boundness; use fresh soil; ensure good drainage; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone. Water early in the morning to minimize evaporation and fungal issues. Allow excess water to drain away completely.
Watering Schedule Tips
Water deeply once per week during active growth, reducing frequency in winter to every 2–3 weeks. Adjust based on rainfall and soil moisture retention.
Soil Improvement
Add compost or well-rotted manure to enhance fertility and structure. Incorporate perlite or sand for drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat; browning leaf edges in cold stress.
Cold Stress
Plants may become dormant or die back in freezing temperatures if not properly mulched or protected.
Solution: Apply a 2–3 inch layer of mulch around the base in fall to insulate roots. Avoid overwatering before cold snaps.
Hot Stress
Leaves may scorch, wilt, or drop in prolonged heat, especially if soil is too dry.
Solution: Provide afternoon shade in extreme heat, increase watering frequency, and use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; avoid late-season feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring. Avoid excessive nitrogen, which can reduce flowering. Discontinue fertilizing in late summer to allow dormancy.
