When it comes to butterfly bushes, also known as Buddleja davidii, there are certain varieties that are considered less invasive than others. It is important to choose a variety that is well-behaved and does not pose a threat to the natural ecosystem.
One such variety is the ‘Blue Chip’ butterfly bush. I personally have experience with this variety and have found it to be a fantastic choice for a non-invasive butterfly bush. It is a dwarf variety, reaching only about 2-3 feet in height, making it perfect for smaller gardens or containers. ‘Blue Chip’ produces beautiful blue-purple flowers that attract butterflies and other pollinators.
Another variety that is known to be non-invasive is the ‘Lo and Behold’ series. This series includes varieties such as ‘Blue Chip Jr.’, ‘Ice Chip’, and ‘Lilac Chip’. These dwarf butterfly bushes have a compact and rounded growth habit, reaching about 2-3 feet in height. They offer a range of flower colors, from blue and white to lilac, and are highly attractive to butterflies.
In addition to these specific varieties, there are also certain cultivars of Buddleja davidii that have been bred to be non-invasive. These cultivars often have sterile flowers, which means they do not produce viable seeds, reducing the risk of spreading and becoming invasive. Some examples of these non-invasive cultivars include ‘Miss Ruby’, ‘Pink Micro Chip’, and ‘White Profusion’.
It is worth noting that even though these varieties and cultivars are considered non-invasive, it is still important to be mindful of their growth and spread. Regular pruning and maintenance can help keep them in check and prevent them from becoming overly aggressive in the garden.
To summarize, when choosing a butterfly bush that is not invasive, consider varieties and cultivars such as ‘Blue Chip’, ‘Lo and Behold’ series, ‘Miss Ruby’, ‘Pink Micro Chip’, and ‘White Profusion’. These options offer beautiful flowers and attract butterflies while remaining well-behaved in the garden. Regular pruning and maintenance will help keep them under control and ensure a harmonious coexistence with the surrounding ecosystem.
