Other Information


Calystegia silvatica, also known as woodbind or woodland bindweed, is a perennial vine native to Europe, Asia, and North America. It is a member of the Convolvulaceae family and is closely related to plants such as morning glories and sweet potatoes. Woodland bindweed is characterized by its large, heart-shaped leaves and showy white or pink flowers. It is a herbaceous plant that grows in a variety of habitats, including woodlands, meadows, and fields. Woodland bindweed is not considered an invasive species and is not known to cause significant damage to crops or other plants. It is sometimes grown as an ornamental plant due to its attractive flowers and large, distinctive leaves.


Large bindweed, Calystegia silvatica, is a vining plant that is commonly found growing in woodlands and along forest edges in the northern hemisphere. It is a hardy plant that can grow up to 10 feet tall and is known for its distinctive heart-shaped leaves and large, trumpet-shaped flowers that can range in color from white to pink.

One of the most notable features of large bindweed is its vigorous growth. This plant has a long, creeping stem that can spread out to cover large areas of ground, making it ideal for use as a groundcover or for erosion control on steep slopes. The stem of the plant is covered in small, pointed leaves that are green on top and slightly paler on the underside.

The flowers of large bindweed are particularly impressive, growing up to 2 inches across and appearing in clusters along the stem. They bloom from June to August, attracting a variety of pollinators such as bees, butterflies, and hummingbirds. The flowers are followed by small, round seed capsules that contain tiny black seeds that are dispersed by wind and can easily establish new populations of the plant.

Despite its attractive appearance and hardy growth, large bindweed is considered to be an invasive species in many parts of the world. Its rapid growth and tendency to spread out of control can quickly overtake native vegetation, choking out other plants and altering natural habitats. For this reason, it is important to monitor and control populations of large bindweed in areas where it has been introduced.

Large bindweed can be propagated by both seed and stem cuttings. The seeds are best sown in the fall and will typically germinate the following spring. Stem cuttings can be taken from mature plants in the summer and rooted in a well-drained soil mixture.

This plant is generally considered to be low maintenance, as it requires very little in the way of care and attention. It is important to keep it well-watered during dry periods, especially during the first growing season after planting. Large bindweed is also tolerant of a wide range of soils and is able to grow in conditions ranging from full sun to light shade.

Large bindweed is commonly used in a variety of horticultural applications, including groundcover, rock gardens, and woodland gardens. It can also be used as a climbing vine on trellises, arbors, and other structures. This plant is a great choice for gardeners who are looking for an attractive and low-maintenance plant that will provide a long-lasting display of flowers.

Despite its invasive nature, large bindweed has also been used for medicinal purposes in some cultures. The roots and leaves of the plant have been used to treat a variety of ailments, including digestive problems, skin conditions, and respiratory issues. However, it is important to note that consuming large quantities of large bindweed can be toxic, and it should not be used as a medicinal treatment without the supervision of a qualified healthcare professional.

In addition to its medicinal uses, large bindweed has also been used for food in some cultures. The young shoots and leaves of the plant can be consumed raw or cooked, and are said to have a mild, slightly sweet flavor. However, it is important to note that the plant's seeds and stems are poisonous, and should not be consumed.

Large bindweed is also of interest to scientists and researchers, who have studied its invasive nature and growth patterns. Research has shown that the plant is capable of rapidly colonizing new areas and outcompeting native vegetation, which can have significant impacts on local ecosystems. Scientists are also studying the plant's root structure and growth habits, in the hopes of finding new ways to control its spread and protect native habitats.

In conclusion, large bindweed is a fascinating and versatile plant that has a long history of use for both ornamental and medicinal purposes. Despite its invasive nature, it remains a popular choice for gardeners and landscapers, and is an important subject of scientific research. Whether you are interested in its beauty, its history, or its impact on local ecosystems, large bindweed is a plant that is well worth exploring.
