Passionflower, Official (Passiflora incarnata) seeds, organic
$4.95 – $31.10
Family: Passion Flower (Passifloraceae)
Hardy to Zones 6 to 12
(Maypop, Passion Flower, Passion Vine) Herbaceous or woody vine, native to the southeastern and eastern US. The flowers are wonderfully large, three dimensional, complex, purple and white. The plant prefers full sun, dryish soils and a trellis. The first year or two, while the plant is getting established, you need to keep them watered and weeded. After that, you just provide a place for them to climb. Useful in making seasonal, living shade structures and for landscape/fence adornment. Traditional usage (TWM): sodorific. Plant prefers full sun and dryish soils, trellis. These can easily be trained up a sunny wall on the porch to give seasonal shade, and the flower display is a big plus. Probably the best germination will be achieved by soaking seeds in warm water for 2 days, then nicking with a sharp blade and planting in warm conditions. Germination occurs within 30 days. However, other methods have long been used, such as giving the seeds a 30 day period of cold, moist refrigeration before planting in warm soil. Seed sown in the fall sometimes germinates reliably in the spring. Here’s another trick that sometimes gives fast results: Soak seeds in a jar of water placed in the bright sun for 2 days and nights up to a week, then plant about 1/2 inch deep in fast-draining mix and keep evenly warm. Work seedlings up in successively larger pots and plant out to landscape at a spacing of at least 4 feet apart.
Packet contains 20 seeds

I bought a packet of your seed this spring and have 2 beautiful seedings- only 2 I think because i soaked but did not scarify. Is it too late to purchase another packet and try again, scarifying this time around?

Hi Margaret,
Thanks for contacting and congrats on your passionflower seedlings–they are innately superior to plants grown from root cuttings. I do think you’d get better results by nicking and soaking before planting. Since very warm conditions are favored, you might get more than last time. With perennial plants like this there is no particular planting window required, one just gets them going and integrates to landscape as weather and opportunity allow. There are more ways to germinate (or fail to germinate) passionflower than there are ants in an anthill. Quirky it is. I once missed a fruit when picking in the fall and the following spring had a whole cluster of seedlings where the fruit had rotted back into the ground next to a rock… richo

after germinating, can seedlings be kept at household temperatures or is extra heat still required?

hi bryn, when it wrinkles, then when you open it the flesh is clear and semi-sweet, the seeds black. r

Followed my “hot process” in the questions and got 75% germ in the first 5 days! Expect the rest to come up in the next week or so!

Not a question, but just wanted to share my experience with growing Passiflora incarnata from seed since I’m usually on here dropping tons of questions! 🙂 I’m lucky to live in the Southeastern USA where we have these growing everywhere! Several years ago, I ran some experiments and then also found an academic article talking about their (much more professional and scientific) experiments. (I’ve now followed this process with seeds from the previous summer AND even 2-year-old seeds with barely reduced germination with the 2-year-old seeds).
What they (and I) found is that these seeds love HEAT. Like, way more heat than most seeds would survive!
— First, I boil water and allow it to cool to around 175 F (so – not much cooling!)
— I actually clip off the sharper end of the seed before soaking
— Then pour the VERY hot but not boiling water over the seeds and sit the glass on a heat mat overnight
— Plant the next day (I’ve used regular seed starting mix in cells, coir or peat pellets- whatever’s clever) and keep the seed tray both covered AND on a heat mat. I like to do this indoors or, if it’s already warm outside- that will work. I’ve taken the temp of the soil/seed starting mix and germination is best with soil temp at around 90 F. Yes- 90!!
Following this crazy hot process, I get about 98% germination in less than a week!
I just ordered a packet since we moved and I found myself without seeds or plants and don’t want to wait another year to get going, so this is what I’ll be doing with my Strictly Medicinal seeds come next week! 🙂

We tried this method and luckily decided to only do it on half the seeds while we did the package instructions on the other half. We’ve seen zero of them germinate after 2 weeks, while the package instructions group is just under 50% germination . And we followed precisely, used a thermometer and everything.

So odd! I had 95% germination with last year’s strictly medicinal seeds as well. This has never led me astray over the years, but I’m not super exact and it could be I do something intuitively (I’m guessing moisture?) and didn’t think to catalog it. 🤷🏽♀️

I used the “hot process” on the maypop seeds I got from you and got 4 out of 10 to sprout. None of the 10 seeds I just planted without doing anything germinated.

Melody (verified owner) –
I inadvertently soaked way more seeds than I needed for planting this year. Any thoughts if I dried them well that they would still be viable for next season? (I did not nick them yet) Thanks.

Hi Melody,
Thanks for staying in touch. I do think, that since they’re not nicked yet, that you can dry them off. However I recommend planting more than you think you need because germination is rarely as much as you expect. That’s why despite the relative difficulty of producing these seeds we’ve kept the packet at 20–to assure that you get something out of the packet. richo

I planted the seeds in January 2021. 4 germinated, which I was very happy with, seeing as other vendor’s maypops didn’t germinate at all. I planted in May, against my south wall, and the vines started blooming late July. (I have sandy soil, which they seem to love) In August, they were covered with flowers, and little fruits starting forming. Unfortunately, there wasn’t enough time for the fruit to ripen (except 1!), even though the plants were covered in decent sized fruit. This spring, a couple plants came back vigorously, while others less so, and some didn’t make it. It is to be expected, as I live in Zone 5/6 (near London, Ontario) and I didn’t cover the ground during winter. The ones that did make it are thriving, covered in flowers once again, beginning early July. I will have to see if some fruit ripens this fall, but even if so, it is worth to grow just for the beautiful flowers and their scent.

Hello Juan, Sorry, these sold out early. You can still get them in “glorious garden.” I’m hoping next year will be a more bountiful harvest–harvest isn’t until November. They’ll pop back into availability at that time. We have plenty of plants if you want to go that route. Richo

The vine was beautiful but I had no flowers. Not sure it it doesn’t flower first year? I also had bought some from another vender andonly one plant from all the seeds. I am ordering more today from you! Any suggestions on flowers?

Hi Christina,
Low germ on passionflower seeds is the nature of the beast. New vines might not flower in the first year. A south facing exposure, deep and dry soils, and not too much nitrogen will help plants overwinter, thrive, and make plenty of flowers. It might be best that your plant didn’t flower the first year–flowering will rob some resources from a perennial that is not yet established. Keep going! Our passionflower potted plants are a good option, it can easily take 2 years to get there from seed… richo

Thank you, Richo! Ill tell ya I had two delicate plants I raised nd didn’t think they would make it. boy I was wrong it went everywhere!!! I’m worried it wont come back for I live in Kansas so I am gonna take your advice and then maybe cut it back nd bring it in this year? I bring in other tropical with good success. I usually order fro you. In fact I have over 60 herbs that seed came from you all! Always very very happy.

The best passionflower I’ve seen in the wild is in Kentucky which has very cold winters. I think it will come back, it is a late riser, you will see it later in the season.

Sandra Lindberg –
I love this vine and have read that there is a variety native to central and southern Illinois. But I’m uncertain. I live in 5b in central Illinois. Could I heavily/deeply mulch a passionflower vine in a dry, south-facing location and hope it would overwinter? I’m doing this with two Chicago Hardy Fig shrubs I put in this year. Any advice?

Hi Sandra,
Your question brought up a little research project for me, and I ended up changing the zone designation on Passionflower from a zone 7 to a zone 6. Our seeds are from a northern hardy strain, I do think you can overwinter it in Central Illinois, and the roots run very deep, so it may be that finding a well-drained site is more significant in overwintering than mulching, which makes things wetter.

I ordered 2 packets in the spring. I planted all 20 seeds in 6 ounce cups and like 10 in a 5 gallon bucket. I soaked for 2 days and sand papered some seeds and nicked some seeds. I got 7 plants only needed 4. I have ordered P.Incarnata seeds from other vendors and none grew. There are aggressive little plants popping up all around my main 4 that are trellised. Very Pleased and never opened second seed packet.

Hello Lee, Thank you for sharing this info. Passionflower can be a very challenging germinator. On our part we are dedicated to selling only seed from the recent harvest, and although this helps, it is not the whole story. Thanks for helping tell the rest of the story. Richo

I live in Western Washington. Hardy Zone 8. I have full sun space for these. Is this the variety that can be used for passionflower tea? I have done some research on these and found that grown in containers they are more prone to root rot diseases over winter. Would it be best to plant these deeply in the ground and generously mulch them. Or would it be better to grow in a container, cut back in winter and bring them indoors?

Hi Jennifer,
Yes, this is the Passionflower most commonly used by herbalists. The plants do send their roots very deeply into the ground and they prefer a dry site. It is best to plant in the early spring and transplant to a sunny spot in early summer.
