The ‘Hibiscus Painted Lady’ is a captivating tropical plant known for its vibrant, multi-toned blooms. It is a popular choice for gardeners seeking to add exotic beauty to their landscapes or container gardens, with its striking appearance and continuous flowering in suitable climates.
Understanding Hibiscus ‘Painted Lady’
The ‘Hibiscus Painted Lady’ (Hibiscus rosa-sinensis) is a vigorous evergreen shrub, typically reaching 6 to 10 feet tall and spreading 4 to 6 feet. It forms an upright, rounded column of dense foliage, or can be trained as a small ornamental tree. Its glossy, dark green leaves are often heavily scalloped, providing a rich backdrop for the spectacular flowers.
‘Painted Lady’ features extra-large, single blooms, measuring 6 to 8 inches across. These captivating flowers are rosy-pink with a deep burgundy or dark red throat. Soft white or pale pink veining emanates outwards from the center, often accompanied by slightly wavy petal edges. In mild climates, they bloom nearly year-round, providing continuous color from late spring through early fall in temperate regions.
Planting and Care Guide
Light
‘Hibiscus Painted Lady’ thrives in full sun, needing at least 6 to 8 hours of direct sunlight daily. In northern climates, full sun is ideal, but in hot, arid regions, partial shade during intense afternoon hours can prevent stress. For indoor plants, a sunny western or southern exposure with at least 4 to 5 hours of bright, direct light is recommended for blooming.
Water
This plant requires consistent moisture, especially during its active growing season. Water freely during warm weather, ensuring the soil remains consistently moist but never waterlogged, as standing water can lead to root rot. Water when the top 1 to 2 inches of soil feel dry to the touch. During extreme heat or drought, daily watering or even twice a day might be necessary.
Soil
‘Hibiscus Painted Lady’ prefers well-draining soils rich in organic matter; sandy loam is ideal. It tolerates various soil types, including well-draining clay, loam, and silt, performing best in a slightly acidic to neutral pH range of 6.0 to 7.0. Amending sandy soils with compost improves water retention and nutrient availability.
Fertilizer
Regular fertilization from spring through fall supports vigorous growth and prolific blooming. A balanced fertilizer, such as 10-10-10 or 20-20-20, can be used. Hibiscus plants particularly need potassium (the third number in a fertilizer ratio) and benefit from formulas with a low middle number (phosphorus) and a high third number, such as 2-1-3 or 17-5-24. Fertilize every 2 to 6 weeks during the growing season, or use a half-dose more frequently with each watering.
Pruning
Pruning maintains the ‘Hibiscus Painted Lady’s’ shape, promotes bushier growth, and encourages more blooms, as flowers form on new growth. Significant pruning is best done in early spring as cooler weather gives way to warmth, before new growth buds fully open. You can also prune in late winter before buds form by cutting back the entire plant by about one-third. When pruning, make cuts at a 45-degree angle just above an outward-facing leaf node or branching stem to encourage lateral growth. Dead or damaged stems can be removed at any time.
Overwintering Hibiscus ‘Painted Lady’
In regions outside USDA Hardiness Zones 9-11, ‘Hibiscus Painted Lady’ must be overwintered indoors due to its sensitivity to cold. Before bringing the plant inside, typically when nighttime temperatures consistently drop below 50°F (10°C), prune it back by about one-third to make it more manageable. This also stimulates new growth for the following season.
Once indoors, place the plant in a warm spot with plenty of bright, indirect sunlight, ideally a sunny western or southern exposure. Reduce watering significantly during winter, allowing the soil to dry out almost completely between waterings, as the plant enters a period of reduced growth or dormancy. Stop fertilizing altogether. Leaf drop is normal during dormancy, but the plant will resume new growth in spring.
Addressing Common Issues
‘Hibiscus Painted Lady’ may encounter some common issues. Yellowing leaves can indicate overwatering, underwatering, nutrient deficiencies, or sudden temperature changes. Consistent, appropriate watering and a balanced fertilization regimen can often resolve this.
Bud drop, where flower buds fall off before opening, is a frequent concern. This can be caused by temperature extremes, insufficient light or humidity, inconsistent watering, or sudden environmental changes like moving the plant. Pests such as aphids, thrips, and spider mites can also cause bud drop by feeding on developing buds.
Aphids cause sticky residue and curled leaves, while spider mites result in stippled leaves and fine webbing, particularly in dry conditions. Mealybugs appear as white, cottony masses and can hinder flowering. A strong spray of water can dislodge many pests, and insecticidal soaps or neem oil are effective organic treatments.
