The difference between edible and ornamental mums
Not all chrysanthemums are created equal when it comes to consumption. The vast array of chrysanthemums (or mums) fall into two main categories: ornamental and edible. Ornamental varieties, commonly found in garden centers and florists, are grown for their aesthetic appeal and are often treated with chemical pesticides and fungicides that are not safe for human consumption. The potential risks are not limited to chemical contamination; many ornamental mums, particularly those with a higher pyrethrin content, can cause allergic reactions in sensitive individuals.
Edible varieties, however, are specifically cultivated for culinary use and are grown without harmful chemicals. Key edible species include Chrysanthemum morifolium, often used for tea, and Glebionis coronaria (formerly Chrysanthemum coronarium), known as shungiku or tong ho, which is prized for its edible greens. Another variety, C. indicum, is also used for its flowers and leaves. Consuming chrysanthemums safely depends entirely on proper identification and sourcing from trusted, pesticide-free suppliers.
Culinary applications of safe chrysanthemums
With careful sourcing, edible chrysanthemums offer a unique, aromatic, and sometimes peppery or bitter flavor profile that can be incorporated into various dishes. The flowers, leaves, and tender shoots are all used in different culinary traditions.
Common culinary uses include:
- Chrysanthemum Tea: One of the most popular uses, this herbal tea is brewed from the dried flowers of varieties like C. morifolium. The resulting brew has a mild, floral flavor and golden hue.
- Salads and Garnishes: Fresh petals and young leaves of edible varieties can be used raw in salads to add a distinctive color, flavor, and texture. They can also be used as a garnish for various dishes.
- Stir-fries and Soups: In East Asian cuisine, especially with the greens known as shungiku, edible chrysanthemums are added to stir-fries, hot pots, and soups. They should be added at the last minute, as they cook very quickly.
- Blanched Greens: Edible chrysanthemum greens can be briefly blanched and then dressed with a simple seasoning, such as a sesame dressing, for a flavorful side dish.
Health benefits and potential risks
Edible chrysanthemums have a long history of use in traditional medicine and are known to contain beneficial compounds. They are a source of vitamins (A, C, B vitamins) and minerals, along with antioxidants like flavonoids. Research, primarily from animal studies, suggests potential benefits such as antioxidant, anti-inflammatory, and neuroprotective effects, as well as possible help with blood pressure and cholesterol management. However, these traditional uses and preliminary findings should not replace professional medical advice, and more human studies are needed.
Despite the benefits, several risks are associated with chrysanthemum consumption:
- Allergic Reactions: As a member of the daisy family (Asteraceae), chrysanthemums can cause allergic reactions, including contact dermatitis, skin rashes, or respiratory irritation, especially in people sensitive to daisies or ragweed.
- Pyrethrin Toxicity: Certain varieties contain pyrethrins, natural insecticides. While less toxic to humans, they can cause mild symptoms like vomiting, nausea, or diarrhea if large amounts are ingested. Importantly, pyrethrins are highly toxic to pets, especially cats and dogs, so ornamental mums should always be kept out of their reach.
- Pesticide Contamination: As mentioned, store-bought ornamental varieties can be treated with pesticides, making them unsafe for consumption.
Safe sourcing and preparation guide
To safely incorporate chrysanthemums into your diet, follow these key steps:
- Source from Trusted Providers: Purchase edible varieties from reputable suppliers who specialize in culinary herbs and flowers. Good options include farmer's markets, health food stores, and online marketplaces that guarantee pesticide-free products. Do not consume flowers from florists or garden centers.
- Proper Identification: If harvesting from your own garden, be 100% certain of the specific variety. If in doubt, do not eat it. Focus on known edible species like C. morifolium and Glebionis coronaria.
- Wash Thoroughly: Even edible varieties should be gently washed to remove any dirt or insects. For flowers, a simple dip in room-temperature water is sufficient, followed by drying on a paper towel.
- Introduce Gradually: If it's your first time consuming chrysanthemums, start with a small amount to check for any allergic reactions or sensitivities.
- Use in Moderation: As with many herbal products, moderation is key. Overconsumption, particularly of the tea, might lead to adverse effects.
