Magnolias aren’t known to be poisonous, but their showy fruit isn’t something people eat as food. The part of the tree that does belong in the kitchen is the flower, not the fruit.1the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick The bright red seeds that make the pods look so appealing are mostly a lure for birds.
What the Magnolia Fruit Actually Is
Most magnolia seeds form inside a large, cone-like fruit made of many small pockets.2Scott Arboretum & Gardens. Magnolia Seed Harvesting – Scott Arboretum & Gardens The pockets stay dry and split open when ripe to reveal brightly colored seeds.3PubMed. Fleshy seeds form in the basal Angiosperm Magnolia grandiflora and several MADS-box genes are expressed as fleshy seed tissues develop
Each seed has an outer fleshy layer filled with oil, wrapped around a stony inner layer.4PubMed Central. How Seeds Attract and Protect: Seed Coat Development of Magnolia As the seed ripens, the red coat softens and builds up the same kind of pigments that color carrots.5PubMed. Fleshy seeds form in the basal Angiosperm Magnolia grandiflora and several MADS-box genes are expressed as fleshy seed tissues develop The coat exists to attract animals, so birds swallow the seeds and later drop or bring them back up.6Plant Ecology & Diversity. Birds and ants can favour the germination of an endemic Neotropical magnolia In some magnolias, seeds whose coat hasn’t been removed by birds or ants don’t sprout at all.7Plant Ecology & Diversity. Birds and ants can favour the germination of an endemic Neotropical magnolia Plenty of bright wild berries are inedible to humans, so color alone tells you nothing about whether something is food.
What Happens If You Eat the Seeds
One forager found the first bite of a southern magnolia seed sweet and pleasant, but the next bite tasted like a mouthful of gasoline.8Foraging Texas. Magnolia Under the red coat sits a pale tan kernel, and either part may supply the harsh taste.9Foraging Texas. Magnolia The seeds are rich in strong-smelling oils, including the pine-scented compounds found in turpentine.10PubMed Central. The Potential of Magnolia spp. in the Production of Alternative Pest Control Substances The harsh flavor often makes people spit the seed out, though young children and pets may still swallow some.
Southern magnolia seed oil is about 70 to 80% unsaturated fat, much of it the same fats found in olive oil.11Google Patents. Magnolia grandiflora seed oil-containing cosmetic with anti-allergy efficacy But that oil is used for cosmetics, not cooking.12Google Patents. Magnolia grandiflora seed oil-containing cosmetic with anti-allergy efficacy There is no tradition of eating magnolia seeds, and it’s best not to.
If a child or pet swallowed a seed, there’s usually no emergency. Magnolias aren’t on the usual lists of poisonous garden plants, and the most likely result of one seed is a mild upset stomach. A dog may drool or retch from the taste. Over the next several hours, watch for repeated vomiting, diarrhea, unusual sleepiness, or other odd behavior. Call poison control for a child, or your vet for a pet, if symptoms appear or if a large number of seeds were eaten.
The Strong Compounds Inside Magnolia Seeds
Southern magnolia seeds contain honokiol and magnolol, two compounds that strongly block an inflammation pathway in the body.13PubMed. Neolignans from North American Magnolia species with cyclooxygenase 2 inhibitory activity They also appear in the fruit of other magnolias, which are being studied for anti-inflammatory use.14Planta Medica. Novel anti-inflammatory neolignans and dineolignans from the fruit of Magnolia obovata
They are biologically powerful: honokiol from magnolia seeds kills mosquito larvae at very low doses.15PubMed Central. Toxicity and possible mechanisms of action of honokiol from Magnolia denudata seeds against four mosquito species Researchers are now testing magnolia extracts as natural insecticides and food preservatives.16PubMed Central. The Potential of Magnolia spp. in the Production of Alternative Pest Control Substances
That doesn’t make the tree dangerous to you. Mosquito larvae are tiny, so a very small amount of a compound can be a large dose for them and a trivial one for a person.
Lab results show what a purified compound does, not what eating whole seeds would do. A handful of seeds contains an unknown and uneven dose, so don’t eat seeds or make home remedies from them hoping for health benefits.
Some people do already meet these compounds. Magnolia bark extract is sold as a dietary supplement, and makers can measure a dose, which is exactly what a homemade seed preparation lacks. Anyone who takes prescription medication, or who is pregnant or nursing, should ask a doctor or pharmacist before using any magnolia product.
Magnolia Flowers Are the Edible Part
Magnolia petals are edible, and the youngest ones, from buds or just-opening flowers, taste best.17the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick Petals grow more bitter as the flower ages.18the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick The common pink-and-purple saucer magnolia is the one most used in cooking.19the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick Its petals have a powerful clove and ginger flavor.20the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick Different magnolia types taste different, and no variety is known to have toxic flowers.21South Seattle Emerald. The South End Guide to Foraging Your Food: Spring 2024 Edition
Petals can be eaten fresh, cooked, pickled, or dried for tea.22the Guardian. Pickled magnolias: spring’s first flowers are edible, with a potent spicy kick Because the flavor is strong, use them like a spice rather than a salad green.
Pick only from trees you know haven’t been sprayed with pesticides, and skip trees beside busy roads where dust and exhaust settle on petals. At home, rinse the petals and pull off the tough base where each petal attaches.
For a simple pickle, pack young petals into a clean jar and cover them with a warm brine of vinegar, sugar, and salt. Keep the jar in the refrigerator and use it within a few weeks. The petals work like pickled ginger, alongside rice or fish.
The first time, taste one petal before cooking a batch. Expect heat, not sweetness. Stop if your mouth tingles or itches.
Can Magnolia Cause a Rash or Allergy
Magnolia leaves can give some people a red, itchy rash, caused by honokiol and magnolol.23Wyndly. Magnolia Allergy: Recognizing Symptoms and Seeking Treatment The magnolia family is one of the plant groups besides daisies that can trigger allergic skin rashes.24Current Medicinal Chemistry – Anti-Inflammatory & Anti-Allergy Agents. Effects of Natural Products on Contact Dermatitis People already allergic to plants like chrysanthemums or ragweed may also react to magnolia.25Curex. Magnolia Pollen Allergy: Spring Bloom & Real Causes This kind of reaction is delayed, and a rash may appear a day or two after contact.
If you suspect contact, wash the skin with soap and water as soon as you can, which helps remove plant oils. Wear gloves and long sleeves the next time you prune or gather from the tree. See a doctor if the rash spreads, blisters, or doesn’t improve over several days.
When Pods Ripen and What to Do With the Seeds
Southern magnolia pods ripen from August to October, turning from green to reddish brown.26Tree Services Charleston WV. Collect & Plant Southern Magnolia Seed Pods Easily They’re ready when they begin to split and show red seeds.27Tree Services Charleston WV. Collect & Plant Southern Magnolia Seed Pods Easily Collect them when they first crack, before animals take the seeds.28Gardener’s Path. How to Propagate Magnolia Trees from Seed
If you want to grow a tree, remove the red coat, since seeds still in their coat may not sprout.29Plant Ecology & Diversity. Birds and ants can favour the germination of an endemic Neotropical magnolia Soak the seeds in water overnight, then rub off the oily coat on a screen. Wear gloves to avoid a rash, and rinse until only the dark shell remains.
Seeds usually need a winter-like cold period before they sprout. Store cleaned seeds in damp sand in the fridge for about three months, then sow them in spring about half an inch deep. Expect slow growth, and years before the tree flowers.
Fallen pods can be raked into compost. Don’t let pets chew on them, and expect wildlife to visit for the seeds.
