The term “wax flower” refers to several different plants, causing confusion about their edibility. Some plants with this common name are non-toxic, while others can cause adverse reactions if ingested. Therefore, positive identification is crucial before consuming any part of a plant.
Understanding Different “Wax Flowers”
The common name “wax flower” applies to various distinct plant species, each with unique characteristics and edibility profiles. One prominent example is Hoya carnosa, also known as the Wax Plant or Porcelainflower. This vining plant features thick, succulent leaves and produces clusters of star-shaped, waxy flowers, often pink or white, with a sweet fragrance.
Another plant frequently referred to as wax flower is Chamelaucium uncinatum, commonly known as Geraldton Waxflower. This Australian native is a shrub with fine, needle-like leaves and waxy, five-petaled flowers ranging from white and pink to purple. Stephanotis floribunda, or Madagascar Jasmine, is another plant called “wax flower.” It is a woody climbing vine with glossy, dark green, oval leaves and clusters of intensely fragrant, pure white, waxy, trumpet-shaped flowers.
Edibility of Specific Wax Flower Varieties
Edibility varies significantly among plants known as “wax flower.” Hoya carnosa is non-toxic. Its flowers produce a sweet, edible nectar. While nectar from Hoya species has been traditionally used in some cultures, the plant’s primary appeal is ornamental and it is not typically consumed as food.
Chamelaucium uncinatum, the Geraldton Waxflower, is an Australian native with edible leaves and flowers. Its pine needle-like leaves have a zesty, citrusy flavor, similar to lemongrass or kaffir lime. They can be used as a culinary herb in dishes like seafood and sauces, or in beverages such as gin. The flowers are also edible, but should be consumed in smaller amounts.
Conversely, Stephanotis floribunda, or Madagascar Jasmine, is toxic and not suitable for consumption. Its fruit is not edible. This plant is primarily valued for its highly fragrant, ornamental blooms, often used in bridal arrangements.
Safe Identification and Consumption Practices
Positive identification is paramount before consuming any plant to ensure safety. Never consume wild plants or any plant unless its identity is absolutely certain. Even plants generally considered non-toxic can cause mild allergic reactions or digestive upset. Also, ensure any plant intended for consumption has not been treated with pesticides or other harmful chemicals. Consuming large quantities of any unfamiliar plant, even those deemed edible, is not advisable.
Responding to Accidental Ingestion
In case of accidental ingestion of an unknown or potentially toxic plant, immediate action is necessary. Contact a local poison control center or a veterinarian without delay. In the United States, the national Poison Help line is 1-800-222-1222, available 24/7. Monitor for symptoms including nausea, vomiting, abdominal pain, diarrhea, skin irritation, difficulty breathing, or seizures. Do not induce vomiting unless instructed by a medical professional.
