Katie Rose Molina Browning and Scott Gallant
As we look to find niches and stack functions in our tropical permaculture homesteads, one often overlooked group of plants include the edible flowers. With a focus on Costa Rica, this blog, authored primarily by Katie Browning, a certified herbalist, explores the many common and uncommon edible flowers available to us in the tropics. Most of these plants fit comfortably within the principles of permaculture and they can be described by the following set of patterns:
- Nearly all of these plants are perennial and can be described as perennial vegetables.
- Most feature strong medicinal qualities as well, hence our partnership with an herbalists to complete this list.
- All of these flowers bring relationships with pollinators, beneficial insects, and often result in delicious fruit if not harvested as vegetables.
- There use is either raw/fresh, as a cooked/steamed vegetable, or in herbal teas and beverages.
If you know of other edible flowers which should be on our list, please add them in the comments and we can grow this list together.
If you would like to see how edible flowers can be incorporated into your landscape and menu consider joining us for one of our upcoming Permaculture Design Courses!
AMAPOLA
Common name: Amapola (Spanish) Hibiscus (English)
Latin binomial: Hibiscus rosa-sinensis
Blooms: All year
Flavor: Sour/sweet/juicy
An abundant and beautiful edible flower that you can find lining most yards and back roads in Costa Rica. It has a cranberry-citrus, nourishing flavor that is slightly sour, sweet and a bit juicy in texture. This juicy ‘goo’ is from Amapola’s very beneficial healing mucilage content which helps sooth all the mucous membranes in the body. It can be a beautiful garnish to a salad, as a decoration for special cakes and deserts, or as a side garnish of a main plate. As a tea, Hibiscus is tasty and helpful for the blood/circulation, digestion and for Women’s health issues. Amapola is typically red though varietals come in many different colors. Like many Malvaceae family flowers, many Hibiscus species are edible.

These stunning flowering bushes are a common ornamental in Costa Rica, though are generally new to cultivation in Central America. The whole flower of both tuberous and wax Begonias are edible. The blossoms of the tuberous varieties have a lemony- citrus taste and the petals can be eaten raw and used in salads or fresh dishes as a garnish for the plate. The colorful blossoms can also add a creative and beautiful dimension to cocktails and refreshments! The wax varietals are more fleshy and can be consumed raw or cooked. With a crisp and moist texture they are wonderful for salads and sandwiches, added to soups or pasta dishes or used as a tasty and fun element for dips.
Cautions/Contraindications: Contains oxalic acid and should avoided by people with kidney issues, gout or rheumatism.
CARAO
Common name: Carao (Spanish) Carao Tree (English)

Family: Fabaceae
Blooms: Beginning of dry season
Flavor: Green, slightly sweet
The seed pods of this beautiful flowering tree are well known in Costa Rica for a nutritive and medicinal infusion called ‘Miel de Carao’, commonly used for anemia and hemmoraging. The sweet pink flowers are the lesser known edible delight! These flowers add a nice element mixed in salads or can be added at the end of simmering a soup. Carao flowers contain some of the same properties as the seed pod and can add a nutritive element to your dishes.
Cautions/Contraindications: Use with caution during Pregnancy.
CLITORIA
Common name: Clitoria/Campanita (Spanish) Butterfly Pea (English)
Latin binomial: Clitoria ternatea
Family: Fabaceae
Blooms: Year round
Color: Blue, blueish purple and white
Flavor: Mild, slightly bitter and sweet
This sexy low climbing, vining plant brings beauty to your dishes alive with its gorgeous blue hues. Use it as a garnish in salads or as a natural colorant for cakes, rice, drinks and much more. Butterfly Pea can imbue a beautiful natural dye ranging from blue to green to magenta depending on the solvent used. Clitoria flowers are traditionally drank as tea, used in rice and also battered and fried in Asian cuisines. One of its most interesting uses is as a tea it can bring on lucid dreams. Aparajita or Koyala is very well known in India and in Ayurvedic medicine, particularly for the nervous and digestive systems. Clitoria alba is the beautiful white flowered cousin of Clitoria ternatea.

Common name: Cana agria (Spanish) Spiral Flag or Red Button Ginger (English)
Latin binomial: Costus woodsonii- Red Button Ginger AND Costus barbatus- Spiral Flag Ginger
Family: Zingerberaceae
Blooms: All year
Flavor: Sweet and juicy
These beautiful types of Costus Gingers are seen growing throughout Costa Rica and line both roadsides and beaches in particular. Pick the little yellow flowers that emerge from the red cone. They taste like nectar and I have been hooked ever since! Usually, I just like to nibble on them fresh as I walk past, but they can also be collected and used as a tasty salad garnish.
Like its cousin, common Ginger, the rhizomes of Cana Agria have many medicinal properties. The gorgeous white flower is also edible! It is crunchy, sweet and juicy and almost like a sugar coated candy, but as a beautiful flower version. I personally have had a hard time eating them beyond serving a decorative purpose, though they can also be chopped up and put in dishes.
Cautions/Contraindications: Do not take in medicinal doses during pregnancy.
COLA DE ALCARÃN
Common name: Cola de Alcarán (Spanish) Blue Porterweed (English)

Pick the little purplish blue flowers from the tail like portion and add to your salads or stir-fry. The best part is they taste like mushrooms! Adding them to other cooked greens helps imbue this flavor. An interesting traditional use of this plant is the leaves were used because of their bitter flavor and dark color to make beer, hence its English name Porterweed. Medicinally the benefits are vast and have an affinity for the digestive, respiratory and integumentary systems.

Family: Apocynaceae
Blooms: All year. Particularly dry season
Flavor: Pungent, sweet, tangy
This woody, vining plant grows throughout tropical Central America and is a popular flower for consumption in El Salvador and Guatemala, with lesser known uses in other Central American countries. In general it is the unopened flower buds that are harvested and used much like a vegetable, eaten with rice or other traditional foods. Loroco has a lot of significance to local street foods and they are added to ‘pupusa’, a popular stuffed tortilla in El Salvador and in Guatemala they are an essential ingredient of ‘pollo en crema’, a rare and celebrated delicacy. If you are looking to just experiment, Loroco goes well with veggies like Zucchini, is good in pasta dishes, cooked in omelets, sprinkled in soups and is also wonderful with white cheeses!

Many ‘Campesinos’, particularly in the mountain regions of Costa Rica, have traditional dishes where Madero Negro flower is used. The tasty, sweet and fresh green flowers are consumed in small amounts raw, such as a salad garnish though they are best when cooked. They can be added to many dishes such as a Picadillo con Huevos (see recipe below), with fish or chicken, and they can also be battered and fried. The whole plant has medicinal use – as a folk remedy for coughs/colds/fever and also as a topical remedy.Its antiparasitic properties make it a popular bath dip for animals.

In parts of the Caribbean islands, cloves, cinnamon, bay leaves, allspice and/or ginger are added, In Jamaica it’s often drank with Rum! Whereas, in its native West Africa the cold drink is made with mint leaves. A hot tea can also be made and whether hot or cold, Hibiscus sabdifera has many incredible medicinal benefits as well. It is rich in antioxidants and wonderful for the heart, blood and circulatory health as well as for immunity. Sorrel or Saril (Sah-reel), as it is known in English also imparts a vibrant reddish-pink dye and can color everything from the tea water to fabrics.

Blooms: All Year
Flavor: Bitter when Raw, Eat Cooked. Leaves have citrusy/sour taste
This beautiful flowering tree is a very popular ornamental tree in tropical and subtropical regions throughout the world and attracts pollinators like hummingbirds, though it has become invasive in some areas. At least nine Bauhinia species have edible parts and it is worth noting a new endemic species was discovered in Costa Rica/Panama in 2018, however Bauhinia proboscidea has not been researched as edible (yet!). The young leaves, flowers, nectar, seeds and seed pods can be eaten like a vegetable. While some Ticos know of the edible flowers, most knowledge of the edible usage stems from India and parts of Asia where flower buds are often pickled, cooked or made into a chutney. For instance, Kachnar is a local name in the Indian subcontinent for the edible buds collected from the tree and it is used to make traditional kachnar curry, prepared using kachnar buds, yogurt, onions and native spices.
A Great traditional recipes for cooking with Bauhinia from traditional Indian and Nepalese cuisine can be found here. The orchid tree also has many traditional medicinal uses particularly in Asian and Ayurvedic medicine. In scientific studies Bauhinia has been shown to have exciting antioxidant and anticancer properties.

Flavor: Green and juicy
If you don’t fancy the slimy texture of Okra, give the flower a try! The green seed pod of this Mallow family plant is well known in the Southern US, India and parts of Africa, however a lesser known edible part of the plant is the flower. Okra flower can be stewed or fried similar to the seed pods and taste similar to asparagus. Or, for a fresher flavor add the chilled blossoms to a salad. The flowers can also be dried and used as a tea, which offers similar benefits as Hibiscus to cool and sooth digestive system. Picking the flowers especially when there is an abundance of pods can help to keep the mass of woody dried pods at bay.
Cautions/Contraindications: Use caution similar to Hibiscus
MORINGA

Latin binomial: Moringa olifera
Family: Moringaceae
Blooms: Dry season
Flavor: Fresh, pungent and a hint of spice
This gorgeous fast growing, drought resistant tree from the Indian subcontinent has recently become a popular tree to plant due to its incredible range of benefits as a food, medicine and regenerative crop. A true Mother tree, it is also one of the most nutrient dense plants in the world. Beyond what you may have already heard about its popular leaf and seed powder for a vast array of medicinal uses, what is commonly unknown in the Western world is that its flowers also carry dynamic uses as a food and medicine. These precious white beauties that bloom with abundance during dry season are first and foremost delicious! Pick one and try! From the first burst of fresh green to the end hint of spice, Moringa flowers carry enough flavor to be eaten by themselves. They also have a long history of use in Indian and African dishes, in which multiple scrumptious recipes can be found.
Being a serious Indian food lover one of my personal favorites is Sojne phool bati chorchori, a Bengali Drumstick tree flower curry!
I also love just experimenting and enjoy Moringa flowers in my tropical version of a salad, which includes the Moringa leaves as well. Seriously, I can’t imagine a dish like salads, stir-fries and curries, that would not be better with an addition of Moringa flowers. To top it off, Moringa flower tea is delicious and carries benefits for nearly every body system particularly the digestive, immune, and nervous systems. Drink hot or cold for all the nutritive and supportive benefits.
Cautions/Contraindications: Moringa has potential interactions with Thyroid, Diabetic and High Blood Pressure medication.
MARACUYA

Latin binomial: Passiflora edulis (most common edible fruit species) or incarnata (most common medicinal species)
Family: Passifloraceae
Blooms: Can bloom year around in tropics after the vine is established
Flavor: Green
This exotic tropical beauty is one of my all favorites as a medicinal, and its flower is edible too! Passionflower is a beautiful garnish for deserts and drinks that are bound to impress. It can also be used in salads to add a mild vegetable taste with a big show, or as a topping centerpiece on a main dish. To harvest make sure you find flowers that are wide open and cut at the base of the stem at the back of the flower. To enjoy both its edible and medicinal benefits it is best made into tea; the flowers, leaves and tendrils can be used for this either fresh or dried and steeped at least 15 mins. The unique flavor will also leave your nervous system and digestion supported and relaxed.

Edible Flowering Fruit Trees
BANANO
Common name: Banano (Spanish) Banana (English)
Latin binomial: Musa paradisiaca
Family: Musaceae
Blooms: Blooms and fruits only once and grows to full in 12-15months
Flavor: Mildly Bitter (unless prepared or cooked).
The incredibly unique and phallic Banana blossoms are also known as the Banana hearts. Once you see one in person you will never look at this herb (not actually a tree) the same! While much of the world shares in the obsession of partaking of the sweet fruit, the blossoms are also a treat and can be eaten both cooked or raw. If you consume raw make sure to find a non-bitter variety. After harvest, the tough purple outer covering is removed and the tender white part of the blossom is exposed. This is then sliced and let sit in water to leach the sap. Try the tender white blossom chopped with things like shredded Papaya and Carrots for a yummy salad. It has the texture of bamboo shoots or heart of palm. Cooked Banana flowers have deep tradition in South Asian cuisines. They can be chopped and added to soups and stir-fry or steamed and peeled like artichokes to be used with dips. Banana flowers a nutritionally rich in fiber, potassium, calcium, phosphorus, iron, magnesium and vitamin E.
Here is a recommend resource on exactly how to harvest, prepare, and cook with the flowers.

Young Mango leaves and flowers can also be boiled and added to dishes like soups. To receive both the scrumptious and beneficial aspects of the flower, try making into a cool infusion by soaking the flower overnight in cold water, straining and then refrigerating a few hours before drinking. This yummy ‘agua fresca’ cools the body and is beneficial for inflamed digestive issues and headaches.
Cautions/Contraindications: Please Note! Mango is in the same family as Poison Ivy and some people have a severe allergy to Mangos, which also transfers to ingesting the flower.
