Evening Primrose

Evening Primrose in all their glory!

Evening Primrose is a magnificent gift from God.  The whole plant is edible and medicinal.  This is one of those prime examples of “Letting food be your medicine and medicine be your food”.  I have a deep love for this cheery plant and it is EVERYWHERE where I live. Especially on my acre cause I’ve collected seed heads and spread them far and wide. Can’t get enough of it’s vibrant joy!

Evening Primrose

Botanical Name: Oenothera biennis  [ee-no-THEE-ruh by-EN-iss]

Family:  Onagraceae

Common Names: evening star, fever plant, king’s CURE-ALL

Evening Primrose is identified by its tall and dramatic flowering stalk.  It can grow to over 6 feet tall!  The leaves are 3-6 inches long, whitish midrib, margin is entire, basal.  The first year plant forms a rosette of leaves that is flat to the ground, later forming a stalk with alternate leaves. The plant flowers during its second year.  The flowers are fragrant with 4 yellow petals that stand out at a right angle from the plant!  The fruit are elongated capsules filled with small black seeds containing the oil.  It blooms from June to September.  As the name implies, the flowers are open in the evening, some say they open at 8:45 pm. (though where I live they smile throughout the days as well)

Leaf: early leaves are tastier, though they are edible at any time the tougher they are the more boiling they need! Best as a cooked green

Stem: way too woody but can be mashed for poultices to heal bruises

Root: Spring  Roots taste rather parsnippy and peppery.  Roots can be dug in the Winter (according to Linda, I’ve never tried it) First year plant root is optimal, it dies after the second year.

Flower: harvest in full bloom right before use.  Use to decorate salads, cream cheese…  Can keep a flower stalk in a vase of water and pick the flowers as they bloom to use in cooking or in an infused oil.

Seeds: the green seedpods can be considered the fruit but are officially seedpods once they dry out. collect seeds to plant elsewhere, use medicinally (high in GLAs), eat them

Evening Primrose is often found in gravelly dry soil, along roadsides and in waste areas.  Cultivation tips:  Biennis in the name indicates that it is a biennial plant that grows for only two years. Spread the seeds sown directly in the soil outdoors in mid-spring.  EVP seeds require light to germinate require light to germinate so scatter them on the soil’s surface, tamp gently and bottom water.   Space plants 8-12 inches apart.  Likes full sun but will tolerate part shade.  Reseeds EASILY.

The young leaves pop up early in the Spring and are a prime indicator that a tasty root is there waiting to be prized.  I collected many first year plant roots in the Spring and dried them to reconstitute later in soups and stews.  I like eating the root with carrots and parsnips. The young leaves are tasty as well, I prefer them boiled or stir fried to raw though.  Young leaves can be eaten as a vegetable or in salads.  Dried or frozen to store.  Buds are edible before flowering.  Collect the tiny black seeds from the seed pods in the fall and use them as a GLA supplement by grinding and storing in another EFA type oil (fish, flax etc). Or storing whole (preferably cool) and grinding as needed on a daily basis and adding the seed meal to foods; smoothies, hot cereal, fruit salads, nut butter etc.  Roots may be eaten raw or cooked.  Dry for long term storage. Decorate salads with the flowers which taste jasminy and delicious.  Make an herbal infused honey with the EVP flowers and chopped up fruits.

1.Linda Runyon says “Rumor has it that oil from this delectable wild flower is one of the most expensive, as well as most beneficial for humans.  It’s composition close to the constituents of mother’s milk, evening primrose offers many medicinal remedies”.

2. Use the infused Evening Primrose Oil in creams and lotions for skin and cosmetic value

3. EVP therapeutic value comes courtesy of its rich concentrations of three nutrients (GLA, tryptophan and quercetin).  The seed oil contians gamma-linoleic acid (GLA) and omega 6 faty acid that the body uses to sooth inflammation and support the immune system.  It also help keep blood flowing freely, reduces high blood pressure and lowers bad cholesterol,  few other plants are such rich sources of GLA. ( GLA is responsible for many of the herb’s properties. It is an anticoagulant that is thought to reduce high blood pressure, prevent heart attacks and guard against coronary artery disease.)

Secondly, EVP seeds, are also a good source of the amino acid tryptophan, which the body converts into the mood-improving brain chemical serotonin.

and thirdly, the plant’s leaves are our best source of the bioflavanoid quercetin, which keeps blood vessels healthy, improves circulation, and eases asthma.

4. The opening of Evening Primrose flowers is a magical site.  Some say they all open at around 8:45 each night.  Would be worth watching this happen.

5. The Ojibwas used the whole plant, soaked in warm water, to make a poultice to heal bruises.

6. Key herb for effectively treating PMS, the dried root made into a tea is helpful for menstrual cramps

7. Key herb for treating eczema

8. “A study by the Highland Psychiatric Research Group at the Draig Dunain Hospital, Inverness, Scotland, found that evening primrose encouraged regeneration of liver cells damaged by alcohol consumption. Other researchers think it may also prevent alcoholic poisoning, hangovers, postdrink depression and alcohol withdrawal. It is thought to stop alcohol from damaging brain cells by bolstering them with unsaturated fats”  Herbalpedia

9. I like using the infused oil in salad dressings or as one of the oils I use when creating herbal lotions and creams for cosmetic use.

Holly’s Evening Primrose Adventures:

Today was one of those epic days with perfect weather, no bugs, slight breeze, lots of herbal gifts in prime energy waiting to be picked.  First I went to the Cattail stream to collect seed stalks (not sure if they are ripe seeds but I’m hoping to spread them to closer ponds and marsh areas), while there I gathered gorgeous purplish blue Lobellia flowers…
Next I went to an island park here in Todd, where the Evening Primrose stalks were heavy with yellow flowers, I collected several cups of these beauties to make Evening Primrose oil with for salad dressings.
Carrion berries were out in abundance but I don’t know anything about their edibility, just their beauty. Anyone know?
Then onto the llama farm, where the Peppermint and Hops were joyfully collected for a Winters store.
I stuck the Cattail seed stalks in the marshy earth near streams and nearby ponds in hopes that they will multiply their bounty closer to my home.
All the gifts are garbled, hanging to dry, tincturing in Scotch whiskey or vinegar, or packed in oil. A good feeling after a day of adventure and shopping in the wild.
Oh and the Goldenrod is prime for the pickin!

Kiva Rose’s thoughts on Evening Primrose

Evening Primrose an amazingly versatile herb. Incredibly nourishing, gentle and very effective, I count it as among my most important herbal allies!
Here’s my most up to date writeup on it from Kiva’s website http://medicinewomantradition.org/oenothera.html
I’m writing a piece on it (and it’s close relative Gaura) for the Medical Herbalism Journal shortly, and will do more updates to my monograph then.

Briefly though, here’s a rundown of some EP highlights:

Nervine – relaxing and grounding and uplifting all at once in a gentle way.
Mood Enhancer – lovely for GI related depression or other mild to moderate depressive states
Anti-spasmodic – Great for uterine and other repro. cramping.
Endocrine tonic – Don’t know exactly how it works but it does seem to have some overall nourishing and calming/relaxing effect on the repro and endocrine system.
First Aid- Great externally as liniment, salve or poultice for all kinds of cuts, scratches, bug bites/stings and so on.
Gut soother – Improves and stimulates digestion while cooling and healing the gut, works REALLY nicely with Plantain and/or Chamomile for all kinds of gut inflammation and pain.
Note the EP oil is a commercially extracted oil made with the seeds. You can make something similar yourself with the seeds but it won’t be as concentrated.

  1. Holly, I just love your website and and all of this info on Evening Primrose. I’ve just recently discovered how great it is. I had a pituitary tumor (prolactinoma),after coming off birth control, that caused me not to ovulate correctly and lead to a host of other endocrine problems. Most of it resolved after I finally got pregnant and breast-fed for 16mos.. But I was still having a little trouble with dryness and not sweating. I hadn’t had to wear deoderatnt for years. I heard Rosalee de la Foret, on Herb Mentor talk about it being helpful for adding moisture to mucous membranes so I got some Evening Primrose oil. I was amazed at how well it worked(within 2-3 weeks) and not only did it help with moisture but I am now sweating normally too! I have fallen in love with this plant and the more I learn about it the more I love it!

    • Wow Tamra that is a fascinating story. Thanks for sharing. I LOVE this plant too.
      I’m spreading it’s seeds everywhere to share the wealth.
      Such a vibrant plant with many mysteries to discover.

  2. Greetings from Japan!
    Was looking for some information on evening primrose and found your blog…
    Thank you for the information and for sharing your recipes…
    We shall try and see what we can do with this plant, as like you, they are all over our potager…

    • How cool to hear from you across the globe. Evening Primrose has many species and it is wonderful to think that people everywhere can enjoy it. I’ve been collecting yet more of the EVP seeds to spread the bounty.
      Thanks for reading my blog! Be blessed today!

    we are living in Brooklyn, so Evening Primrose is not growing wild around here. How can we get it as plants? Can it be ordered? Does it re-seed, or is it a Perennial? thanks

    • It’s actually all over the fields near the seashore in and around Brooklyn. Look for it in Marine Park, Floyd Bennet Field, Fort Hamilton Park, and Plumb Beach, as well as in Ft. Tilden Park and Jamaica Bay in nearby Queens. I’ve also found it just north of the Boathouse in Prospect Park, where I lead foraging tours.

  4. Amanda Baker says

    I just harvested primrose leaves and root for the first time. Can I make an infused oil with these constituents (roots and leaves) that will be effective or does it need to be prepared as an essential oil professionally from the seeds? Thanks for your thoughts.

  5. Michelle says

    I use the stem of the Evening Primrose that grows at my cabin to make bracelets. The stem gets sort of a bark on it, and when it does I lay it down and gently hit it with a rock to crack the sides. Then I peel the cracking parts off (it should come in very thin, see-through strands) and soak them in water for a few minutes. I take the thin strands and twist them the way a rope is twisted, adding more as the length runs out. It takes a bit of practice and my hands get sore after a while but I’ve been wearing my bracelets for a year now and they have held up. They hold a lot of meaning to me considering how amazing this plant is!

  6. Marie Mayes says

    I moved into a duplex that had an Evening Primrose plant growing along the fence. How can I collect the seeds to take with me when I move again 🙂

    • Evening Primrose seeds are prolific. The greed seed pods will become brown and break open as they dry, within are thousands of tiny little black seeds. I love to take a 5 gallon bucket to an Evening Primrose patch at this stage and break off the stalk shaking them upside down in the bucket to collect the harvest of seeds. I also like keeping the dried seed pods for nature crafts (make great forest fairy arms) or for dried seed stalk arrangements) Evening Primrose keeps on giving!

  7. Lane Dusenberry says

    Hello Holly, I am trying to find a recipe for Evening Primrose blossom jelly,(if one even exists). So far this year, I have made Wisteria blossom, Dandelion, and Rose petal jellies… ( all grown on our property). Do you know of a recipe for evening primrose jelly ?

    • Wow Wisteria jelly! What does THAT taste like?!? You have just added to my bucket list!
      I have never tried Evening Primrose blossom jelly not sure it would taste like much. I’d rather eat the tender blossoms in a salad. Let me know if you try it.

  8. I have Missouri Evening Primrose in my garden and wanted to grow more plants from seeds. My plants have a ‘cylinder-type’ green shape growing with the flowers, which I think contains the seeds. Is that a correct assumption? Any ideas on what I do the ‘harvest’ the seeds and grow seedlings?

    • Hi Allie,
      Thanks for your question.
      The seeds will evolve as the plant ages and the seed pods turn brown. When the seed pods are green the seeds are immature.
      I love to eat the flower buds and the young tender seed pods are delicious when prepared properly.

      • Is there an easy way to get the seeds out of the pods to sprinkle them on my breakfast cereal and on salads like chia and flax seeds?

  9. I would like tips on how best to prepare, cook EVP buds. Tried steam I cooking the still green buds along the stalk. Steamed them as I would carrots or string beans but, for longer – 10 mins. They didn’t taste very edible I’m afraid ; bland, the pods still coarse and, ‘grainy’ texture due to the seeds inside.

    • Hi Gail, I really prefer the flower buds to eat either raw in salads or lightly sauteed. The seed pods have a fleeting tasty factor (really young and still tender) but this doesn’t last long. I mostly gather them to freeze and use all winter in bone broth. The nutrition is so off the charts awesome and that is one excellent way to enjoy it.

  10. I have a question. If I don’t harvest the flowers, will the plant produce more seeds?

  11. Noelle Gomes says

    I have just discovered this plant this evening as I walked out of the back of my apartment unit to take out the trash. Seeing this beautiful yellow flower, I stopped and picked, bud, leaf, and flower to look it up. What a pleasant surprise to find this lovely and useful plant growing here in Rhode Island.

  12. Hi Holly! This is SO facinating and I am obsessed with learning more about herbal remedies. I need to know how to process my evening primrose for use through out the year. Like drying them? Or using as a tincture? Do you have a book or a guide on your website that gives these instructions? I mostly love the fact that you are giving God the glory for His creation and that everything He made was for a reason. God bless you!

  13. The seeds in my green pods are white… I saw you said the should be black seeds?


  1. […] Evening Primrose is prominent now among the host of Goldenrod, Asters, Ironweed, Joe Pye weed, and other late Summer bloomers. Actually Evening Primrose has been featured all Summer.  Being a biennial plant it’s second year plants are mostly going to seed but there are still plenty of first year basal rosettes available that make the perfect addition to my wonton soup.  The whole plant of Evening Primrose is edible and indeed medicinal, but the roots have a parsnippy flavor to them and make for good eating.  The leaves I chopped with my herb scissors into the soup pot for the last 10 minutes of cooking.  You can learn more about EVP here.
