Should I Remove Wisteria Seed Pods

You can observe either smooth or fuzzy seeds if you open a wisteria seed pod. The smooth seeds are North American, whereas the fuzzy seeds are from Asian kinds. The most vigorous and potentially invasive wisteria kinds are those from Asia.

In the late summer and early fall, a healthy wisteria vine will yield seed pods. Like peas, the pods dangle from the vine. It is advisable to remove the seed pods from an established wisteria plant to preserve it blooming. If the plant is left unattended, the pods will ripen and release seeds that will shoot out many feet (approximately one meter) from the plant. The seeds shouldn’t be let to germinate unless you want a wisteria farm.

Must I get rid of the seed pods?

A healthy layer of mulch to make pulling weeds simpler, watering trees well in hot weather, and removing seed pods from plants before they scatter their seeds all over the garden are all suggested by garden writer Ciscoe Morris.

Wisteria seed pods blow up, right?

Depending on the kind, the climate, and your pollinators, your wisteria will most likely develop seed pods if you don’t deadhead it. Deadheading will stop the development of seed pods altogether.

The seed pods of wisteria actually explode! Wisteria naturally disperses its seeds by making a popping noise, shooting out, and landing a few feet distant. In the late October, the popping typically occurs on a warm day. However, you may easily remove the seed pods before they turn brown or become completely dry if you don’t want Wisteria seeds to cover your yard. Keep in mind that the pods and seeds of wisteria are harmful.

Due to the aesthetics in the fall and winter, when so many gardens are drab and brown, many gardeners prefer to save the seed pods. Observing the pods explode is entertaining, and you may save the seeds to plant later.

On the other hand, since the seed pods are deadly if consumed, you might want to remove them. Removing them also stops the yard’s grass seeds from spontaneously springing everywhere. It will leave more space for the buds to grow in and offer you a better glimpse of their cascading petals if you remove the pods now.

Wisteria may be grown from seeds, but it may take your plants many years to blossom and they won’t look exactly like the Wisteria you acquired the seeds from. The best time to gather Wisteria seeds for planting is in the fall, after the pods have dried out and turned brown but before they have popped. You can plant wisteria seeds in the spring or the fall.

Do all Wisteria produce pods?

Although wisterias have lovely flowers, Peter Valder observed that some individuals appear astonished to find the plant’s seed pods. When Peter Valder recently visited some Mt Wilson gardens, he took a closer look at these plants.

Ornamental pods

Like peas and beans, wisteria is a legume that develops seed pods after flowering. The Japanese wisteria (Wisteria floribunda), in contrast to the Chinese wisteria (Wisteria sinensis), produces clusters of long, elongated pods that resemble bean pods and are numerous. Another benefit of the Japanese wisteria is its stunning autumn butter-yellow leaves.


Using a pair of secateurs, get rid of the pods if you’re sick of them and wish to clean up the wisteria before it blooms in the spring.

Don’t cut the stems back too much, as there may be buds that may bloom in the spring. Leave a few centimeters at the top at all times.

Grow your own

Gather the pods and allow them to dry if you want to attempt producing your own wisterias from seed. Gather the pods after the leaves have fallen in the autumn and set them onto a tray to dry because the seeds usually explode from the pods. Twist the pods open, then plant the seeds 2 cm (almost 1) deep in a mix that is readily permeable.

Does the plant need to dry the seed pods?

When seeds are moist, they should germinate, and when they are dry, they should hibernate. It’s crucial to dry your seeds after harvesting them for this reason. The optimum method for drying seeds is open air, and there are various techniques for setting up the ideal environment utilizing common home items.

Let’s go through what it means for a seed to be “dry” first. Your garden’s seeds should be fully mature when you harvest them. That means that for plants with pods or seed heads, such as beans, onions, and the majority of flowers, the pods and seed heads should be completely browned and dried on the plants. Even though the seeds appear to be dry now, rain and dew have nevertheless provided them with a significant amount of moisture. Evidently, seeds from squishy fruits like tomatoes or melon are not dry when they are harvested. In all circumstances, seeds must be dispersed and air dried before they may be safely kept.

Many people who conserve seeds have learned this the hard way. Freshly harvested bean seeds feel dry to the touch, but when placed in a sealed container or plastic bag, they quickly begin to mold since they aren’t actually dry on the inside. When you remove flower seed heads from your plants on a sunny day, they may appear dry, but if you immediately place them in a plastic bag, you’ll find that a few weeks later they are stuck together with mold.

Spreading seeds out so that the air can reach each one and allowing them to dry naturally in the open air are the best ways to dry them. As long as the seeds are dispersed thinly so they may dry rapidly, plates, wide bowls, pie plates, baking sheets, and serving trays are all suitable containers. In an effort to save space, I have occasionally piled the seeds four or five layers high. That’s typically a bad idea because the bottom seeds can’t get any air contact, which makes it difficult for them to dry rapidly. As a result, they either mold or sprout before drying!

Drying your seeds on a screen is an even better approach to get them in contact with the air. Once they have dried both on the inside and the outside, you can spread them a little thicker. Any type of sieve or strainer, frying basket, or salad spinner will work, provided the mesh is small enough to hold the seeds. Window screens also work well and may be attached to a frame with relative ease; alternatively, you might be able to find screens from old windows.

When drying wet seeds, such those from tomatoes, you should strive to have them completely dry in three days. Any longer and there is a chance that they will sprout in your drying pan. Given that you cannot force the roots to re-establish, this is plainly catastrophic for the seeds. Once they have sprouted, they won’t re-germinate.

Here are two suggestions to make the drying process simple, regardless of the technique you choose:

  • As the seeds dry, stir them. This promotes consistent drying and reveals any seeds that have less air contact. Additionally, now is the ideal moment to separate seed clusters that will later awkwardly stay together. You’ve probably noticed how tomato seeds clump together if you’ve ever preserved a lot of them. You won’t have any clumps later if you stir them while they’re halfway dry.
  • Run an electric fan someplace in the room if the seeds don’t dry out quickly enough or if the air is too humid during a week of rain. Air movement of any size can have a significant impact.

Heat is unnecessary and potentially harmful. Some seed savers have experimented with utilizing food dehydrators or ovens set to a “low” temperature to hasten the drying process. There is no “low” setting on an oven that won’t cook seeds because they tend to perish when they are heated even little. More efficient and secure than any type of heat is ventilation and air movement.

Due to the ease of removal, some individuals prefer to dry seeds on parchment or waxed paper. Because paper towels absorb moisture from the seeds, some people prefer to dry their seeds on them. I personally don’t like how seeds attach to paper towels, but a man said it was the greatest option for him during a seed-saving session last week. I don’t contest other people’s achievements.

Above all, take care to prevent seed mixing. Previously, I dried tomato seeds on plates, but I now use cake pans instead because the sides stop the seeds from falling out and mingling.

In the end, trust our arid Canadian winter air to properly dry off your seeds. By November, your home’s air will be sufficiently dry from natural causes for you to store your seeds in airtight jars or plastic bags without risk. Until then, store them in paper bags or envelopes and keep them dry by sealing them. At Seeds of Diversity, we store seeds in jars at room temperature, and if the jars are shut when the seeds are completely dry, they last for many years. For extremely long-term storage, we also freeze seeds, although this requires improved drying with silica gel, a subject for another post.

Why do the pods on my wisteria exist?

In gardens across U.S. Department of Agriculture plant hardiness zones 4 through 9, Wisteria plants (Wisteria spp.) add beauty. Many of these plants produce explosive seed pods in the fall, which can frighten unprepared gardeners and bystanders. The plants produce 4- to 6-inch-long seed pods that resemble giant pea pods when the warmth of summer and the wisteria’s blossoms start to fade. The pods progressively dehydrate as they wait on the tree for a beautiful autumn day, soaking up the sun’s heat until it causes the pods to explode. As a result, a scattering of wisteria seeds fall to the ground and emit a loud popping noise that is frequently mistaken for gunshots. This disperses the seeds far enough from the parent plant so that they can sprout and grow without competition. Many gardeners remove these seed pods before they open because wisteria tendrils spread so far as the plant matures. This prevents the plant from spreading further. However, if you want even more of these lovely plants, you may gather the pods, collect the seeds, and cultivate your own.

Twist the seed pod while holding it over a tray to split it in half and release the seeds. If you’d like, you can put the seed pod in a lidded container and wait for it to automatically pop open, dispensing the seeds into the container for you. Because seed pods open with force, make sure the container lid is sturdy and fastened tightly.

Are the wisteria seed pods toxic?

Eastern and central North America is the home to the ornamental ivy known as Virginia creeper. It features five-leaf groupings of tiny leaves, or leaflets. It is occasionally mistaken for poison ivy, which has leaflets that form clusters of three. Fortunately, unlike poison ivy, Virginia creeper doesn’t contain an oil that can cause rashes. Just repeat yourself, “Leaves of three, let it be; leaves of five, let it thrive,” if you have difficulties remembering which plant is which.

Virginia creeper’s berries and leaves can be poisonous, therefore it’s not entirely non-poisonous. Virginia creeper berries have small crystals called oxalate crystals and resemble purple grapes. Additionally, Virginia creeper leaves contain these crystals. Chewing on the berries or leaves can irritate the throat, lips, tongue, and mouth. Although extremely rare, oxalate crystal-containing plant consumption has been linked to nausea, vomiting, diarrhea, and trouble swallowing. Typically, the symptoms appear fast and might linger for up to half a day.

A climbing vine called wisteria produces clusters of blue or purple blossoms that dangle and are fragrant. Wisteria seeds are housed in velvety, dangling seed pods. All plant parts include the dangerous compounds lectin and wisterin, which, if ingested, can result in a burning feeling in the mouth, stomach pain, vomiting, and diarrhea. The seed pods and seeds are thought to be the sections of the plant that are the most deadly. Once they start, these symptoms might linger for up to two days.

You can assist someone who mistakenly comes into contact with Virginia creeper or wisteria by doing the following:

  • Wipe their mouth with gentleness.
  • To get the plant matter out of their mouth, have them spit while you have them rinse with water.
  • To help rinse the residual substance into their stomachs, they can take a few little sips of water.
  • Sucking on ice chips or other icy foods may provide pain relief for people whose mouths are inflamed.
  • Keep them hydrated by giving them regular, short sips of clear liquids if they are feeling nausea or vomiting.

Check the webPOISONCONTROL online tool for advice or dial Poison Control at 1-800-222-1222 if you believe someone has been exposed to Virginia creeper or wisteria and is experiencing problems.

Canine wisteria seed pods be toxic?

Because wisteria doesn’t have a bad taste, dogs may eat deadly amounts of it.

Wisterias are absolutely gorgeous, with cascades of flowing purple blossoms. However, their leaves and blooms can also be dangerous in excessive numbers, and their seeds (and seed pods) are extremely poisonous to dogs.

Even worse, the results take time to manifest. Wisteria also doesn’t taste unpleasant, making it simple for dogs to consume excessive amounts before you realize there is a problem.

How long does it take wisteria to bloom after being sown?

Generally speaking Typically, wisterias bloom three to five years after being planted. Some wisterias take up to 15 years to mature. Wisterias grown from seeds may take up to 20 years to blossom or they may never do so at all.

Do you remove wisteria blossoms that have died?

To encourage wisteria to bloom for longer, remove any dead blossoms. Immediately following their fading, “Deadhead faded flowers.” More flowers will grow as a result, according to Webb.

How are wisteria plants grown from seeds?

Plant one or two wisteria seeds in each container at a depth of one inch. When the soil surface starts to dry up, water the pot and keep it in a 65°F area. When the seeds are germinating, covering the pot with a plastic bag will help keep the moisture in, but once the seeds sprout, remove the bag.

Are wisteria plants invasive?

Wisteria blooms over roads and arbors in the spring, reminding me that sure, spring always keeps its promise and, wow, this stuff is taking over the globe! Although some varieties of wisteria are stunning, they are invasive plants and should be grown with caution (if at all).

The native American species is a perfect substitute if you adore the rich splendor of wisteria because it provides you all the glory without nearly as much trouble.

Chinese and Japanese Wisteria

Wisteria sinensis and Wisteria floribunda, respectively known as Chinese and Japanese wisterias, are magnificent spring-blooming vines with gracefully twisted trunks and an absolutely gorgeous display of pendulous lavender or pink blooms in the spring. These are the varieties of wisteria that grow wild along highways and drape their foot-long flowers from tall tree branches.

They are very stunning. However, when these non-native vines are accidentally introduced into American forests (often by well-intentioned gardeners), they quickly proliferate and start the troublesome work of obstructing light and water, growing thickets, impeding the growth of new saplings, and even bringing down large trees with their heavy, woody stems.

Despite being invasive species, Chinese and Japanese wisterias are still sellable, and it can be tempting to take a cutting or sprout from a naturalized vine. But before putting wisteria into your yard, you might want to consider how diligently you intend to train and control it.

American Wisteria Is the Native Choice

Consider growing the less invasive American wisteria as an alternative (Wisteria frutescens). This gorgeous vine, which is native to eastern North America, is just as magnificent despite having slightly smaller blooms that occasionally repeat in the fall. It is significantly less intrusive and much less likely to spiral out of control than its Asian counterparts.

The blossoms are the most straightforward way to recognize American wisteria. The flowers of American wisteria are shorter, rounder, and more compact than those of Asian species, which have elongated blossoms with loose, dripping petals (rather pinecone shaped). Despite having less fragrant blossoms than Asian wisteria, American wisteria still has stunning flowers! The smooth seed pods of American wisteria can also be distinguished from the hairy seed pots of Chinese and Japanese varieties.

Don’t be deceived when planting American wisteria by the claim that it is “non-invasive”

The tenacious American wisteria swiftly covers arbors and reaches impressive heights in the trees. In comparison to Asian wisteria, it also grows more quickly and is more resistant to cold. Native to marshes in the southeast, American wisteria thrives in some sunlight.

Wisteria Fact

Did you know that the wisteria vines of various varieties entangle in various directions? While American and Japanese varieties climb clockwise, Chinese wisteria twines counterclockwise.

How to Grow American Wisteria

When cultivating American wisteria in your yard, remember to:

  • Water: Wisteria might require a little irrigation during dry seasons because it is a native of marshes.
  • Use a trellis: Instead of letting wisteria climb trees, train it to a trellis or arbor to keep it under control.
  • Gently Tie: Since wisterias twine to climb (rather than cling), it may be necessary to gently tie them to the trellis until they round it.
  • Keep Pruning: If a vine is not taken care of, it could grow out of control. Maintain wisteria in its intended location and cut back any sprouts or tendrils that stray onto nearby bushes or trees.
