Stephanotis floribunda, also known as S. jasminoides, is often referred to as “Stephanotis” or “Madagascar Jasmine.” While the common names may suggest a close relationship to jasmine, the scientific classification actually places it in a different family altogether. Stephanotis is more closely related to the American milkweed, belonging to the family Apocynaceae, while jasmine belongs to the family Oleaceae.
I have come across this confusion quite often in my gardening and landscaping endeavors. The name “jasminoides” does imply a resemblance to jasmine, and the fragrant white flowers of Stephanotis do bear a resemblance to those of certain jasmine species. However, it is important to note that Stephanotis is a distinct plant with its own unique characteristics.
One key difference between Stephanotis and jasmine is their growth habit. Stephanotis is a vine that can climb and twine around structures, while jasmine plants can be either shrubs or vines. In my experience, Stephanotis vines can be quite vigorous and require regular pruning and training to keep them in check. On the other hand, some jasmine species can be more compact and bushy, making them suitable for hedges or borders.
Another noticeable difference is in the leaves of Stephanotis and jasmine. Stephanotis has leathery, dark green leaves that are opposite, meaning they grow in pairs on opposite sides of the stem. Jasmine, on the other hand, typically has lighter green leaves that are arranged alternately along the stem.
In terms of flower appearance, Stephanotis and certain jasmine species do share similarities. Both produce small, white, star-shaped flowers that are highly fragrant. The fragrance of Stephanotis flowers is often described as sweet and intoxicating, similar to that of jasmine. This is perhaps why Stephanotis earned the common name “Madagascar Jasmine.”
While Stephanotis and jasmine may have some similarities in flower appearance and fragrance, it is important to recognize their taxonomic differences. Stephanotis belongs to the family Apocynaceae, which includes plants like milkweed and oleander, while jasmine belongs to the family Oleaceae, which includes plants like olive and lilac.
To summarize the main differences between Stephanotis and jasmine:
Stephanotis (S. floribunda):
– Belongs to the family Apocynaceae
– Is a vine that can climb and twine
– Has leathery, dark green leaves arranged in pairs
– Produces small, white, star-shaped flowers with a sweet fragrance
Jasmine (Oleaceae family):
– Belongs to the family Oleaceae
– Can be a shrub or a vine
– Has lighter green leaves arranged alternately
– Produces small, white, star-shaped flowers with a sweet fragrance
While Stephanotis and jasmine may share some similarities in flower appearance and fragrance, they are actually different plants with distinct taxonomic classifications. Understanding these differences can help in selecting and caring for these plants in the garden or landscape.
