Water
The Himalayan Butterfly Bush needs regular watering, especially during the growing season. Water it thoroughly, ensuring that the soil is evenly moist, but not waterlogged. It is best to water this plant when the top inch of the soil feels dry to the touch, which may equate to watering once or twice per week, depending on weather conditions. A good approach is to provide the plant with 1 to 1.5 gallons of water each time, ensuring the water penetrates deeply into the soil to encourage deep root growth. During the winter months, you can reduce watering as the plant will enter a dormant phase and require less moisture.
Light
The Himalayan Butterfly Bush thrives in full sun to part shade conditions. It prefers to be placed where it can receive at least 6 hours of direct sunlight daily, though it can tolerate some light shade, especially in hotter climates. The ideal spot for this plant would be in an east or west-facing garden that benefits from bright, indirect light in the afternoon.
Temperature
The Himalayan Butterfly Bush is hardy and can withstand a range of temperatures, but it performs best in environments where the temperatures are between 60°F and 80°F. It can survive minimum temperatures down to around 20°F but may suffer frost damage if temperatures drop lower. During the summer, ensure the plant is not subjected to temperatures above 90°F for prolonged periods as this can stress the plant.
Pruning
Pruning the Himalayan Butterfly Bush is essential for encouraging new growth and more abundant blooms. The best time to prune is in late winter or early spring, before new growth begins. Cut back the previous year's growth to about one-third of its length to promote a bushy form and increase flowering. Pruning should be done annually to maintain plant health and aesthetic appeal.
Cleaning
As needed
Soil
The Himalayan Butterfly Bush flourishes in fertile, well-draining soil with a pH between 6.0 and 7.0. A mix containing loam, leaf compost, and coarse sand in equal parts would create an ideal soil environment that retains moisture yet drains excess water efficiently.
Repotting
The Himalayan Butterfly Bush should be repotted every 2 to 3 years, or when it outgrows its current pot, to ensure it has enough room to grow and sufficient nutrients.
Humidity & Misting
The Himalayan Butterfly Bush prefers moderate humidity levels, typical of outdoor environments, without the need for additional humidity control measures.
Suitable locations
Indoor
Ensure bright light, good air flow, and water when topsoil dries.
Outdoor
Plant in full sun, well-draining soil, and shelter from strong winds.
Hardiness zone
7-9 USDA
Life cycle
Pink Butterfly Bush (Buddleja colvilei 'Kewensis') starts its life cycle when the mature plant's flowers are pollinated, and seeds are formed and dispersed. These seeds germinate in suitable conditions, often requiring a stratification period to break dormancy. The seedlings emerge with their first set of true leaves and continue to grow, eventually forming a small shrub. As the shrub matures, it develops the characteristic woody stems and foliage, along with large hanging panicles of pink flowers that are attractive to butterflies and bees. After the flowering period, seeds are produced for the next generation. Finally, as a perennial, Pink Butterfly Bush may enter a period of dormancy in colder climates during winter, resuming active growth with the return of warmer temperatures in spring.
Propogation
Propogation time
Spring-Early Summer
Propogation: The most popular method of propagation for the Buddleja colvilei 'Kewensis', commonly known as the Kewensis Butterfly Bush, is by semi-ripe wood cuttings. These cuttings are typically taken in late summer, when new growth has matured enough to be somewhat firm but still maintains a bit of flexibility. A cutting should be about 4 to 6 inches (approximately 10 to 15 centimeters) long and include several sets of leaves. The bottom set of leaves should be removed and the cut end dipped in rooting hormone to encourage root development. Then, the cutting is placed in a well-draining potting mix, such as a mixture of peat and perlite. The pot should be kept in a warm environment with indirect light and high humidity until the roots have established, which usually takes a few weeks. It's important to keep the soil moist but not waterlogged to prevent rot.
