Understanding the Geranium Name Confusion
For many, the word "geranium" brings to mind the colorful annual flowers that adorn window boxes and patios. However, these are typically not true Geraniums but rather plants from the Pelargonium genus. Both are part of the Geraniaceae family, but their properties and toxicity profiles, particularly towards animals, differ significantly.
True Geraniums vs. Scented Pelargoniums
True Geraniums, or "hardy cranesbills," are generally perennials known for their symmetrical, five-petaled flowers and hardiness. Most species within this genus are non-toxic to both humans and pets. Scented Pelargoniums, on the other hand, are often treated as annuals and are known for their aromatic leaves, which come in a wide range of scents like rose, lemon, nutmeg, and mint. While edible for humans in small quantities, these varieties contain compounds that can be mildly toxic to pets.
Edible Species and Their Culinary Uses
Once you have correctly identified your plant, you can explore the diverse culinary applications of the edible varieties. The flowers and leaves are the parts most often used to add unique flavors to food and drink.
Culinary Applications of Scented Pelargoniums
Scented Pelargoniums are a versatile addition to the kitchen. The leaves and flowers are both used to impart their distinct aromas.
- Teas and beverages: Leaves can be steeped in hot water to create a fragrant herbal tea, or frozen into ice cubes to add flavor to lemonade or iced tea.
- Baked goods: The leaves can be used to infuse flavor into sugars for cakes and biscuits, or placed at the bottom of a cake tin before baking.
- Jams and jellies: Adding leaves to fruit preserves can introduce a subtle, aromatic flavor.
- Desserts: The flowers can be crystallized or used as a fresh garnish on desserts and ice cream.
- Savory dishes: Some varieties, particularly lemon or ginger-scented ones, can be added to salads, soups, or to flavor grilled fish.
Culinary Uses of True Geraniums
For true Geraniums, edibility varies by species, and proper identification is critical. Some wild varieties have edible flowers and leaves, often with a tangy or lemony taste. For example, the flowers of Sticky Geranium (Geranium viscosissimum) are edible and can be added to salads. However, many species are not considered palatable, and their edibility rating is low. It is always best to consult an authoritative botanical source before consuming any wild plant, for example, the Plants for a Future database mentioned in a forum discussion.
Important Safety Precautions
Consuming any plant requires careful consideration, especially with a genus as complex as "geranium."
How to Safely Consume Geranium
- Positive Identification: Never consume a plant unless you are 100% certain of its exact species. The difference between a safe edible variety and an unpalatable or mildly toxic one can be subtle.
- No Pesticides: Only consume plants that have been grown organically without the use of chemical pesticides or fungicides.
- Moderation is Key: Scented Pelargoniums contain concentrated essential oils, and consuming them in large quantities may have a toxic effect on the body. Start with small amounts to gauge individual tolerance.
- Allergic Reactions: Some individuals may experience contact dermatitis from handling the leaves of Pelargoniums. Test a small amount against your skin before ingesting.
Comparison of Edible Geranium Types
| Feature | Scented Pelargonium | Hardy Geranium (Cranesbill) |
|---|---|---|
| Common Appearance | Often sold as annuals, large fragrant leaves, asymmetrical flowers | Perennial, symmetrical flowers, generally non-aromatic leaves |
| Botanical Genus | Pelargonium | Geranium |
| Edibility for Humans | Leaves and flowers are edible in small, flavoring quantities | Some wild varieties are edible; edibility varies greatly by species |
| Safety for Pets | Mildly toxic due to geraniol and linalool | Non-toxic to pets |
| Culinary Uses | Flavoring for teas, jams, baked goods, garnishes | Wild varieties can have edible flowers and leaves for salads |
| Distinct Feature | Strong, distinct scent in leaves (rose, lemon, mint, etc.) | Hardiness, resistance to frost, medicinal properties in some varieties |
Conclusion
In summary, the edibility of 'geranium' is not a simple yes-or-no answer. The scented varieties, which are botanically Pelargoniums, can be safely enjoyed in small amounts for their aromatic qualities in a range of culinary applications. Conversely, the true hardy Geranium species have varied edibility, and careful identification is always necessary before attempting to consume any part of the plant. Prioritizing accurate plant identification and consuming only certified edible varieties will ensure a safe and flavorful experience.
