Did You Know?
1. Buddleia, commonly known as butterfly bush, can be easily propagated through a technique called softwood cuttings. This involves taking a stem cutting from a young, flexible branch in early summer and rooting it in a pot of well-draining soil.
2. Unlike most flowering plants, buddleia has a unique ability to purify soil contaminated with heavy metals such as lead and zinc. It is often used for phytoremediation, a process where plants help clean up polluted areas.
3. The scent of buddleia flowers, which is reminiscent of honey or vanilla, is known to attract a wide variety of insects, including butterflies, bees, and moths. This is one of the reasons why it is so popular among gardeners looking to attract pollinators.
4. In some cultures, buddleia is regarded as a symbol of transformation and spiritual awakening. It is believed that having a buddleia plant in your garden can bring positive energy and encourage personal growth and renewal.
5. Buddleia plants are considered invasive species in certain regions, such as parts of North America, where they can outcompete native plants and disrupt local ecosystems. It is essential to control their spread and prevent them from becoming a threat to biodiversity.
Growing And Varieties Of Buddleja Davidii
Buddleja, also known as butterfly bush, is a delightful addition to any garden. Buddleja Davidii is one of the most popular varieties, thanks to its ability to thrive in a wide range of garden conditions. This shrub can grow up to 2.5-3m in height, making it a stunning focal point in any garden. However, if you are looking for a smaller option, there are also dwarf cultivars available that only reach 1-1.2m tall.
One of the fascinating aspects of Buddleja Davidii is its versatility in terms of growth habit. It can be grown as an upright bush or pruned into a lollipop-like standard, allowing you to create various aesthetic effects in your garden. Another remarkable feature of this plant is its wide range of flower colors. From delicate white petals to vibrant pink, lilac, blue, and crimson, there is a Buddleja Davidii to suit every taste and design preference.
In the United Kingdom, there are several hardy varieties of Buddleja that can withstand harsh winters. These include B. alternifolia, B. globosa, B. x weyeriana, and B. davidii and its cultivars. However, it is important to note that some varieties may require protection in severe winters. Placing them by a south-facing wall or covering them with horticultural fleece can provide the necessary shelter. On the other hand, tender varieties like B. madagascariensis and B. asiatica should be kept in a conservatory or brought indoors to avoid damage during winter.
Protecting And Caring For Buddleja In Winter
While Buddleja is generally a hardy shrub, it is crucial to take proper care to protect it during the winter months. Taking these preventive measures will ensure the continued health and vitality of your Buddleja plants.
When planting, consider the location carefully. Choose a spot that offers some protection from harsh winds and extreme cold. A south-facing wall can provide extra warmth and shelter.
Covering your Buddleja plants with horticultural fleece is another effective method of winter protection. This material helps to insulate the shrub and shield it from freezing temperatures. It is particularly important in regions with harsh winters or if you have chosen less hardy varieties.
If you have tender varieties of Buddleja, such as B. madagascariensis or B. asiatica, it is crucial to take extra precautions. These plants should be kept in a conservatory or brought indoors during winter to protect them from frost. Failing to do so may result in severe damage or even the death of these delicate species.

Frequently Asked Questions
Will Buddleia cuttings root in water?
Yes, Buddleia cuttings can indeed root in water. To increase their chances of successful rooting, it is advisable to use standing mains water instead of water containing chlorine as it may hinder the process. It is also recommended to cover the cuttings with polythene or glass, as this creates a humid environment that aids in quick rooting. Once the cuttings have successfully rooted, they can be transferred to pots for further growth.
Can you grow butterfly bush from a cutting?
Yes, butterfly bush can indeed be grown from a cutting. To do so, you will need to take a 4- to 6-inch long cutting of a new stem during the late spring or early summer when the stem is strong enough to avoid bending. After cutting, dip the end in rooting hormone powder and then plant the cuttings into a pot filled with moistened potting soil. With proper care and attention, these cuttings have the potential to develop into thriving butterfly bushes.
How do you get seeds from Buddleia?
To obtain seeds from Buddleia, it is a straightforward process. As autumn approaches, the seed capsules begin to dry out and mature. It is advisable to trim the panicle before it is completely dry to prevent the capsules from bursting open and dispersing the seeds. Typically, one would place the seed head in a paper bag and hang it in a cool, dry location to facilitate the seed collection process.
How does Buddleia reproduce?
Buddleia, commonly known as butterfly bush, has a unique way of reproducing. With an astonishing production of up to 3 million seeds per plant per year, it relies on various modes of dispersal. Primarily, the wind plays a crucial role in carrying the lightweight seeds to new locations, allowing them to colonize vast areas swiftly. Additionally, Buddleia seeds can hitch a ride on animals, traverse through water currents, and even catch a lift on vehicles, further aiding in their widespread distribution. This impressive reproductive strategy ensures that Buddleia can proliferate rapidly and establish itself in diverse environments.
