The ‘Kili Rose’ is a cultivar of Hibiscus rosa-sinensis, known for its vibrant, tropical blooms. This variety is admired for its striking floral display, bringing a touch of the tropics to gardens.
Key Characteristics
The ‘Kili Rose’ displays large, single flowers, typically 6 to 8 inches across. Its petals often exhibit a blend of deep pink, red, or orange with a contrasting throat or eye. The edges may also feature a subtle frill. These blooms emerge against glossy, dark green foliage, which contrasts with the vibrant flowers.
Growing and Care
Light Requirements
‘Kili Rose’ thrives in bright, direct sunlight to encourage abundant flowering. Placing the plant where it receives at least six hours of direct sun is ideal for optimal bloom production. While it can tolerate some partial shade, especially during the hottest parts of the day in intensely warm climates, insufficient light can lead to sparse blooming.
Watering Needs
‘Kili Rose’ requires consistent moisture and regular watering. The soil should remain evenly moist but not waterlogged, as soggy conditions can lead to root rot. Allow the top inch or two of soil to dry out slightly between waterings. Signs of wilting can indicate a need for immediate hydration.
Soil Preferences
This plant prefers well-draining, fertile soil with a slightly acidic to neutral pH (6.0-7.0). A mix incorporating peat moss or compost can improve soil structure and provide nutrients. Good drainage is important to prevent water accumulation around the roots, which can be harmful to the plant.
Temperature and Humidity
‘Kili Rose’ performs best in warm temperatures, ideally 60°F (15°C) to 90°F (32°C). It is sensitive to cold and should be protected from temperatures below 50°F (10°C), often requiring indoor relocation in cooler climates. High humidity levels are also beneficial, achievable through misting or using a pebble tray for indoor plants.
Fertilization and Pruning
Regular fertilization supports vigorous growth and flowering, especially during the active growing season. Apply a balanced, slow-release fertilizer formulated for flowering plants, or one with a slightly higher potassium content, every 4-6 weeks. Pruning helps maintain the plant’s shape, encourages bushier growth, and promotes new flower buds on fresh growth.
Common Challenges
Bud drop is a common issue for ‘Kili Rose’, often due to sudden temperature changes, inconsistent watering, or insufficient light. Stabilizing environmental conditions usually resolves this. Pests like aphids, spider mites, and whiteflies can also affect the plant, appearing on new growth or leaf undersides. Early identification allows for prompt treatment with insecticidal soap or neem oil.
