Bought seeds this spring to plant for the pollinators without knowing the various benefits of this vine. Collected flowers and pods today for tea and stir fries. The fact that the flowers are edible and used for food dye is very useful

Easy to grow from seed. Makes a lovely wall of blue/green against my fence. In zone 9, it usually dies back in winter so not invasive for me. Larval host plant for Long Tailed Skipper butterfly.

I collected some random seeds from Thailand about 2/3 years ago and finally planted them in India this summer. (6-8 weeks ago). Today we had our first flower.

So, to answer your question, the seeds picked from a vine seem to be viable for a pretty long period even without any special storage precautions.

I was given seeds from a co-worker. I planted them in my backyard to fill in a hole my puppy dug up. Within 6 weeks this vine began climbing! It boasts beautiful purple and yellow flowers. There is an empty pot beside the plant with potting soil and today, while taming the vine with floral wire, I noticed a pod growing, actually two! We were flooded a few weeks ago so over watering in South Texas is not a problem for this plant. In fact, it's thriving. I have not picked any of the flowers but plan on adding them to salads and experimenting with other dishes as well. The pods will go to my mother. She loves the flowers this vine produces.

I have more of a question than a comment, for anyone here in central Florida. I've planted some Butterfly Pea seeds, and the seedlings are coming up now. Keeping the little pots with the seedling indoors until the spring, except for putting them outside on nice afternoons like today.

For butterfly pea, and basically every other plant listed in Dave's Garden, gardeners are warned NOT to overwater.

Trouble is, a large swath of Florida is in the midst of a drought. This past summer and fall, I yanked out numerous plantings that were dead, the roots bone dry, even crumbling to the touch.

What constitutes "overwatering," in Florida, in the middle of a yearlong drought? It's forecast to continue well into the spring (2017).

@rahuljawale From my experience with Clitoria vines and from what I've read, the things that cause them to produce lush or leggy growth with few flowers are: over-watering; not enough of the nutrients potassium, sulfur and phosphorus; or too much high-nitrogen fertilizer (Miracle-Gro). Ours get shade for about half the day so they need less water than in full sun all day, but I only water them once a week in absence of rain. Every 3 months March through November, I give them 6-8-10 slow-release fertilizer granules with Epsom Salt added for sulfur and a small amount of 2-14-0 for phosphorus. I only occasionally apply Miracle-Gro and only diluted to 1/4 strength. I'm not a professional grower so I don't know if that's the best regimen, but it works very well, as our Clitoria vines remain... read more

I have a Blue Pea Vine which flowered for a few months after it was bought at the local nursery. And then for almost a year, i.e. till today, I have not seen a single flower on this vine. There have been a time of neglect in terms of feeding but I never stopped watering the plant.

Apart from the blooms, there is nothing wrong with the wine, it's growing with healthy rate. I do not see even a single leaf yellowing on this vine.

Can you please help me on what I need to do to make it flower again.

Beautiful vine as others have already said. It is one of the host plants for the Long-tailed Skipper (Urbanus proteus). and this week a female layed eggs on my plant. In my zone 8b it will probably not come back unless we have a mild winter. So far I have not had seeds, but will keep hoping.

I was introduced to this flowering vine in Thailand. We were served Butterfly Pea in the form of cool aid. It was very refreshing. We were then told that it was good for high cholesterol and the flower could be eaten. We tried one and it had a mild sweet taste.
When we came home to Arkansas, I planted two seeds after soaking them until a small root appeared. I was pleased to have a flowering vine growing up a trellis in about 6 weeks. Since then I have shared this mysterious plant with my friends. We have made a drink with it, added it in salads, added it in cookie dough and eaten the flowers picked fresh off the vine.

I live in Everett, WA, about 30 miles north of Seattle. I purchased the seeds from Thompson and Morgan. I sowed them under grow lights with bottom heat in April. I noticed my first bloom tonight with more buds on the way.
The vines were planted in a large container with a trellis to climb. We've had a warm summer. The container is on the east side of our house.
I will plan on starting them earlier next year. The flower is a beautiful blue.

Through this wonderful site, I have just discovered the name and data on a few seedlings I have been calling my "Magical Mystery Plants." I knew they were vines because of their twining nature, but never mind that boring stuff--on with the story!

Earlier this spring, while I was down in the basement searching for one garden implement or another, I espied in a dark corner a crinkled piece of paper, much yellowed and somewhat brittle. When I unwrapped it, I found a few pods and several seeds obviously "beanish" in appearance. The only information written on the page was a woman's name and telephone number--and not a telephone number code from either Canada or the US. Hmm.

In India, Butterfly Pea is commonly known as Gokarn or Kajli. i have this vine in my private garden since four years. and at present, it has reached height of 9 meters by creeping on a nearby tree. now all i do is water it once a day. during rainy season, i avoid watering lest it may rot.

once the Butterfly Pea flower dries itself on the vine, it turns into a bean pod and seeds from these pods can be planted for a fresh vine. if the soil is favorable, the plant reseeds itself.

Easy to grow vigorous annual or perennial in frost free areas. Propagate from seed, plants bloom in 7-10 weeks from germination. Easy to germinate from seed, soak the seed over night, germination from 7-10 days usually 100%. Great for quick fence cover. The plants become leggy quickly so pinch out the terminal buds to keep the plant bushy and flowering where you can see it. Like all pea plants the roots fix nitrogen and improved the soil fertility. Can be grown as a green manure and dug into the soil after 2-3 months. Its edible and can also be used to feed animals. In frost areas collect the seed to replant the next year. Tolerant of a wide range of soils and including alkaline soils. In very hot climates 45C, 113F it appreciates some shade from the afternoon sun.

I purchased 3 of these plants (double flowers) from Home Depot to grow on 3' x 9' trellises. While they started out growing beautifully up the trellis, certain parts of the plant are now wilting, turning yellow and starting to die. Other parts of the plant are still thriving with dark green leaves and an abundance of flowers. I have been cutting away the dying parts of the plant, but I don't now why this happening. I want these plants to cover the trellises, but I am having a lot difficulty. Thinking I should replace them with something else, but they are so beautiful (the parts that are thriving) I don't want to remove them. Any suggestions? Thank you.

It is more of a shrub than vine here in lahore Pakistan. It blooms from June till October. I have one with double blooms and blue color. I am growing it in a clay pot. This is my first experience with this vine. Its leaves are very beautiful. It is fast growing vine. it has reduced flowers in extreme summer heat of over 100F specially in full sun. It is called "Neelofar" locally.

Edible purple food dyes are also extracted from the butterfly pea flower ("anchan" flower) in Thailand, and used in making desserts.

To make your own purple dye from butterfly pea flowers in the Thai way, begin by placing a flower in the bottom of a small glass. Add a little bit of water, then push and grind at the flower with a spoon (the way you would use a mortar and pestle). The water will appear blue at first.

Then, slowly add a few drops of an edible acid (such as lemon or lime juice) until the solution turns purple.

When added to food, the result is a beautiful and demure shade of light purple. Enjoy!

I found the Butterfly Pea last year growing under a Cedar out in the woods. Until recently though a total mystery flower. I have a walking path around the woods and past where It's growing. I hadn't noticed it prior to last year (2006). I searched and asked around but nada. A week ago, I sent a picture around to my family and my daughter replied -- "it looks like..." And voila, I did a search, found Dave's site and it's no longer a mystery. The soil out here, 60 miles east of Dallas, is sandy clay pH unknown. With all the rain and cooler temps we've had this year there are lots of flowers and I'm collecting seeds. The plan is to start it growing close to the house for all to enjoy. Enjoyed looking at all the pictures and uploaded one I took recently.

These grow as cool season annuals here in zone 7/8, going by what I have seen and read online. They reseed so easily that I am happy to have them as annuals. I had the white (alba) variety when I moved to this house last May and was given seeds for the blue last fall (2005). I planted the blue in the spring '06, but with the dry conditions we had this summer, I was afraid I wouldn't get any blooms and might even lose them. Luckily I had one survivor and today I seen my first bloom on it!

This is a favorite perennial in my Florida garden where my original plant is several years old. And I do know it is the original and not a dropped seedling. It has been through freezes and come back from the roots. In a frostless year it is evergreen, but bloom production does fall off alot in Feb and Mar. Just starting to put on plenty of bloom now in April. This is the wonderful double variety. I also have single which does not seem to be as hardy and has to be replanted. And I have the single white in a plant going on 3 years old.

It is a lovely vine to have, esp. the blue one and in particular, the double blues. Flower colour is stunning, easy to start from seed and grow. It can tolerate some neglect. Seed pods have to be removed when it is fully ripe -- you can know by shaking the pod to hear the seed rattle. When pressed along the edges, it opens out like a coiled spring. If seeds are not removed, they can reseed easily and the following growing season, you may find lots and lots of seedlings many feet around it, since the pods throw open with great force to disperse. All in all, it is a beauty.

Blue butterfly pea vine never fails to attract attention. It grows easily here in central Florida. It sometimes overwinters, as Thunbergia alata will. It is tolerant of acidic soil and drought, but shows its appreciation of enough water by growing and flowering with abandon. You can sew seeds directly here in cooler weather. It grows much more easily for me than Morning Glory ever did!

Butterfly pea has naturalized on my property over the past 8 years. It is so a joy to so easily get that gorgeous blue color. It grows in all soil types and is drought tolerant. It does need some sun to flower. Each plant will produce beans that don't taste good, but contain seeds. The germination of these seeds is about 100%. Anyone can grow this vine!

I have searched the internet for 3 days looking for this exact vine. I absolutely LOVED this vine. The flowers are a beautiful blue and the foilage is a consistent gorgeous medium to dark green. Mine did beautifully on the south side of the house where it got about 5 hours of direct mid day sunlight. It grows well without much fuss. (We have a huge oak tree that soaks up most of the water and nutrients from the soil, which has caused a problem for everything else, but not this vine) It could take over the flower bed easily, and that would be o.k. by me. We moved to Arizona and leased our house out and I some how ???? I forgot about the vine until I really got back into taking care of our yard again and I can not wait to have this vine again!
