Butterfly bushes are called Buddleja or Buddleia because they belong to the genus Buddleja/Buddleia, which is named after the English botanist Reverend Adam Buddle. The name "Buddleja" is the original spelling, while "Buddleia" is a later spelling variation that has gained acceptance over time.

Reverend Adam Buddle (1662-1715) was an English botanist and clergyman who was known for his extensive collection of plant specimens. He was the first person to describe and classify the plant genus that now bears his name.

Adam Buddle discovered the Buddleia genus through his extensive study of plants and his observations of the natural world. Buddle was a prolific collector of plants, and he spent many years studying the flora of England and other parts of Europe. The genus Buddleja was posthumously named in his honor byCarl Linnaeus (1707-1778), the Swedish botanist that formalized the binomial nomenclature that we still use today when naming new plants.

Over time, plant breeders developed new cultivars of butterfly bushes with a wide range of flower colors, shapes, and sizes. These new cultivars helped to increase the popularity of the butterfly bush even further, making it a staple in many gardens and landscapes around the world. Currently, the genus includes about 140 species of flowering plants that are native to various parts of the world, including Africa, Asia, and the Americas. These plants are popular for their attractive flowers, which are often fragrant and come in a range of colors.

Buddleia is an important part of a summer garden because of its ability to attract butterflies and other pollinators. The plant's nectar-rich flowers provide a valuable food source for these insects during the summer months, when other sources of nectar may be scarce. Additionally, the colorful flowers of Buddleia add a striking visual element to the garden, providing an eye-catching display of colors ranging from white and yellow to pink, purple, and blue. As a low-maintenance perennial, butterfly bushes are an easy way to add beauty and ecological benefits to any garden.

How to Select a Butterfly Bush (Buddleia):

1. Choose a cultivar that is well-suited for your region: Different Buddleia species and cultivars have different temperature and humidity requirements. Be sure to choose a cultivar that will thrive in your local climate. Here at Plant Delights, we are in Zone 7b, which is idea for many species of butterfly bush.

2. Look for a healthy plant: When selecting a butterfly bush, look for a healthy plant with vibrant green leaves and no signs of insect damage or disease.

3. Consider the size of the plant: Butterfly bushes come in a range of sizes, from compact varieties that grow just a few feet tall to large shrubs that can reach 10 feet or more in height. Choose a size that is appropriate for the space where you plan to plant it.

4. Choose a color: Butterfly bushes come in a range of flower colors, from white and yellow to pink, purple, and blue. Choose a color that complements your garden and your personal preferences.

5. Consider the shape and growth habit: Some butterfly bush cultivars have a more upright growth habit, while others are more spreading or weeping. Choose a growth habit that fits well with the other plants in your garden and the overall design of your landscape.Buddleia 'Honeycomb'

6. Look for a cultivar that attracts butterflies: While all butterfly bushes are attractive to butterflies, some cultivars are especially effective at attracting these beautiful insects. Look for cultivars that are marketed as "butterfly magnets" or "butterfly favorites."

In conclusion, the butterfly bush (Buddleia/Buddleja) has a rich history dating back to the discovery of the genus by English botanist Reverend Adam Buddle. This beautiful plant has become a popular choice for gardeners and landscapers due to its attractive flowers and ability to attract butterflies and other pollinators. With careful selection, you can find the perfect butterfly bush cultivar for your garden. By considering factors such as climate, plant size, flower color, and growth habit, you can enjoy the beauty of this remarkable plant while providing a valuable resource for the local ecosystem.
