While gardeners love flowers for the beauty they provide to the home landscape, few gardeners grow flowers for eating. That’s a shame because many flowers, in addition to being edible, bring lively flavors, colors, and textures to salads, soups, casseroles, and other dishes.
Eating flowers is not as exotic as it sounds. The use of flowers as food dates back to Roman times, and to the Chinese, Middle Eastern and Indian cultures. Edible flowers were especially popular in the Victorian era during Queen Victoria’s reign. So, just what are the guidelines for munching on flowers?
There are some basic guidelines when it comes to edible flowers. Much of this information is pure common sense, but it’s important to be mindful when venturing into new gastronomic pursuits. Many of us do not have a family connection of an experienced “elder” to tell us which flowers might be safely edible, so it’s good to review some basics.
It’s important to be cautious. If you have allergy issues or a compromised immune system, it’s best to skip these adventures with edible flowers unless you have total control over their production.
Identify the flower exactly and eat only the edible parts of those flowers. Tulip flowers, for instance, can be eaten, but only the petals. If the taste of any flower is objectionable — too bitter, too sour, too spicy, or just plain weird — don’t swallow it.
Flowers can vary in edibility depending on the time of year. Once you have established that a flower is safely edible, experiment with its flavor and texture at different times of the year.
Toxicity is a major concern. Some ornamental plants are distinctly poisonous though beautiful, including several adorning gardens at this time of year: bleeding hearts, lily-of-the valley and oleander. Even though a lovely daffodil may seem to be just the thing to top a birthday cake, stay away from using those. Other beauties to avoid eating include hydrangea and Texas mountain laurel.
Be sure flowers are free of pesticides. Regulations for how to use pesticides on food crops differ from regulations for ornamental crops. Be sure that the rose or pansy flower you have your eye on has not been treated with any pesticides which are illegal to be used on a food crop.
Roses, for example, are sometimes treated with a systemic insecticide that is applied to the soil. This should not be regarded as safe for human consumption due to the use of a systemic insecticide that can be present in most or all parts of a plant for several weeks after application.
When choosing flowers for edibility, look for those grown safely. Don’t pluck a flower at random from an unfamiliar location or make the assumption that flowers in florist displays are edible.
In most cases, the petals are the palatable part of the flowers listed as “edible.” Remove the stamens and pistil from larger flowers such as day lilies (the stamens are covered with pollen, which may aggravate allergies).
Reliably edible flowers include calendulas, dandelions, geraniums, nasturtiums, pansies, roses, squash blossoms and sweet violets. This is only a partial list of edible flowers.
One flower that is particularly abundant in many area landscapes is the day lily. While the day lily nowadays is considered a delicacy by wild food gatherers and knowledgeable chefs, it has a long history in Chinese cuisine in addition to Chinese medicine.
Daylily flowers can be used in a variety of ways. They add sweetness to soups and vegetable dishes. Flowers that are half opened or fully opened may be dipped in a light batter of flour and water and fried in a wok. You can add the petals to egg dishes and salads. Dried day lily petals, called “golden needles” by the Chinese, are an ingredient in many Chinese recipes, including hot-and-sour soup.
Some food preparers have suggested that varieties with pale yellow or orange flowers produce the sweetest, most delectable taste. However, it appears that day lily taste is related to day lily cultivar more than flower color according to serious taste trials.
Eating flowers is not a weird or unusual gastronomic endeavor. If you like broccoli or cauliflower or artichoke, then you are already a flower connoisseur since a head of broccoli or cauliflower is composed of a few hundred unopened flowers! The general rule is that the flowers of most herbs and vegetables are safe to eat (with flowers of tomato, potato, eggplant and pepper being notable exceptions). Always check first, because as with anything in life, there will always be exceptions.
The guidelines provided here are definitely related to a common-sense approach to selecting other types of flowers as food. Adding flower petals to a salad or garnishing a stack of pancakes with a small rose can be fun and effective, but it’s necessary to become informed before ingesting your floral creations.
