If you routinely harvest sweet pea blossoms, they will continue to bloom, giving you a strong reason to have lovely flowers in your house. Keep in mind that although sweet pea seed pods resemble edible pea pods, they are deadly and should not be consumed.
Should sweet pea pods be removed?
You must consistently water your flowers throughout the growing season since dry soil causes them to set seed more quickly. When your sweet pea plants are fully bloomed, be sure to deadhead them and remove seed pods as soon as you can to promote the production of new blooms.

Sweet peas are the perfect plants for you if you enjoy using fresh cut flowers to decorate your home with color and aroma. They are excellent for cutting since they grow more as you take more flowers from them. Using our sweet peas center, you can learn everything you need to know about growing and caring for sweet peas.
Are sweet pea shoots edible?
I’m preparing a pea feast for the beginning of spring. Well, broad beans and peas are two reliable GYO staples that are also delicious and so simple to raise as to be required. There is much more to the pea family than the hard, tasteless peas you can buy fresh in the pod at the grocery store, despite the fussy depodding procedure. The taste of freshly selected peas definitely makes up for it.
Really fascinating group of plants is the pea family. The perennial sweet peas will be skipped over, but if you have time, look them up because they are wonderful, floriferous, and garden-worthy plants.
There are several varieties of edible peas and mange tons available as seeds for the grow-your-own enthusiast, including Delicious varieties that offer sweet, soft seeds and pods for raw or cooked treats. There are purple-podded strains available to captivate children or to give color and intrigue to your dishes. Even the real peas and mangetout shoots, tendrils, blooms, and leaves are delectable and eatable (NOT sweet peas) and can be collected for delicate garnishes, micro leaf creations, or for just snacking while they are sprouting in the greenhouse. Be careful not to utilize sweet pea blossoms since they are harmful; instead, use the lovely edible pea and mangetout flowers to make a lovely garnish or to add color and flavor to salads.
Peas are one of the few things that can be sown and produced early in the season due to their hardiness, which is only one of its many wonderful qualities. Finding ways to grow things without the weather rotting, drowning, or washing them out of the soil is also becoming somewhat of an art form given the damp start to the year so far. The greenhouse succeeds once more. Regardless of your knowledge and expertise, they are so dependable and simple to grow that you can always expect a crop.
Those who are fortunate enough to own a greenhouse are equipped with a potent tool. The glasshouse creates a wind and rain proof refuge where the greenhouse gardener may sow, plant, and pot for hours on end sheltered from the weather—unless it has been swamped or blown away in the gales. It’s a fantastic getaway from the craziness of modern life as well as the weather. It’s probably because you somehow tune in with the plants and the garden and re-connect with nature that it’s so soothing and pleasant. Growing food and anticipating the growing season as well as the warmer, drier, and hopefully brighter weather that will come after these biblical floods are both highly satisfying activities.
The greenhouse also provides a safe environment for priceless seeds, seedlings, cuttings, and plants to grow in.
I’ve been planting peas this weekend with the help of a sweet pea growing kit from Unwins that includes a compost bin, seeds, and an unheated propagator. Mostly sweet peas, but a biodynamic producer also sent some heritage edible peas. They were sown two to a module and as they start to grow, will be reduced to one plant per module. It’s a sluggish start, but because the garden is waterlogged and will remain so for some time, everything needs to be scheduled and staged so that it has somewhere to grow when it requires growing space. I’ve also seeded some organic broad beans and spinach alongside. It’s too simple to pack the greenhouse with plants, seedlings, and cuttings right now, but if they don’t have a place to continue growing, there won’t be much space left to plant or sow additional seeds. I need to get better at managing my space because of this lesson. The promise of flowers, herbs, and veggies can be too tempting to ignore as the sowing season approaches. I’m powerless to stop myself.
When planting a variety of items from the same family and species, labeling is crucial because the seedlings may all have the same appearance. Even though I usually believe I’ll remember what I’ve sowed, I always get confused when the greenhouse contains so many pots, trays, and modules of different varieties of the same plant. My sweet pea seedlings will be a mirror image of the heritage peas for quite a long. Thankfully, the bundle also contained some stylish black plant labels complete with a white pen. The end product was labels for my seeds and seedlings that were easy to read and write. Is this finally the ideal response to the difficult label issue? Well, keep an eye on things, but to be honest, they do seem hopeful. Black labels are easier to see, less obtrusive than white ones, and won’t turn into the garden’s ubiquitous weathered, iconic tombstones denoting failing plants or locations where the dog (or cat, or fox) has dug a hole. In the end, I turned to writing on the plastic flower pots, which is OK until you pot them up or plant them out. I’ve tried wooden labels, homemade labels, seed packet labels, aluminum labels, recycled labels, and even handmade terracotta labels.
What area of the sweet pea contains poison?
Sweet pea seeds contain lathyrogens, which are a mildly toxic substance that, if consumed in excessive amounts, can result in a disease known as lathyrus. Lathyrus causes convulsions, difficulty breathing, and paralysis.
Lathyrus sativus, a species that is similar to it and is farmed for both human and animal consumption. Nevertheless, eating too much of this high-protein seed over an extended period of time can result in lathyrism, a disease that can cause paralysis below the knees in adults and brain damage in youngsters. This typically happens after famines, when the seed is frequently the only source of nourishment for protracted periods of time.
Choosing sweet peas and perennial peas
The major consideration is whether or not aroma is crucial to you when deciding between perennial Lathyrus and sweet peas. Decide if you would then like an annual or perennial plant. There are several color choices available as well as climbing and bushier varieties.
Fragrance
Choose sweet peas (Lathyrus odoratus), which are generally very fragrant, if you enjoy a pleasant garden and sweet-smelling flowers for indoor use.
Lord Anson’s blue pea (Lathyrus nervosus), a perennial Lathyus, is an exception to the rule since it does have a perfume.
How long the plant lasts
After setting seed, sweet peas (Lathyrus odoratus) only have a one-year lifespan. However, don’t let this deter you because they are quite simple to grow from seed. Lathyrus latifolius is an example of a perennial species that returns every year, however there are fewer options and they typically lack smell.
Colour
The annual sweet pea (Lathyrus odoratus) has a large variety of blossom colors, including bicolored varieties. However, the perennial varieties do come in some uncommon colors, like yellow and orange.
Habit
The majority of Lathyrus are climbing plants, therefore support them with canes, netting, or allow them to climb over a bank or through a bush. For ground cover and pots, clumping varieties like the spring-flowering Lathyrus vernus and dwarf bushy sweet pea varieties like “Snoopea” and “Bijou Mixed” are excellent choices.
Buying sweet peas and perennial peas
Although many garden centers also sell a few sweet pea seeds in packets, the largest assortment of sweet pea seeds may be acquired from internet seed suppliers. In the spring, several nurseries and garden centers sell pots of germinated sweet pea seedlings that can be divided into individual plants and raised in pots before being planted outside.
There are a few seed specialists who sell perennial Lathyrus seeds, like Lathyrus latifolius, but many gardeners opt to purchase the plants instead. The plant you’re looking for can be found using our Find a Plant tool.
When to plant sweet peas and perennial peas
- Annual sweet peas should be sown either in late January or early April and planted out in April.
- Sow perennial Lathyrus in the spring or the fall.
Where to plant sweet peas and perennial peas
Locate a sunny area where there is room for the plant to grow or to bush out (depending on its habit). Also acceptable is a little light shade, especially for Lathyrus grandiflorus.
How to plant sweet peas and perennial peas
- To avoid cold shock, indoor seedlings should be hardened off for 10–14 days before being transplanted outside.
- Ideally, four weeks before planting, enhance the soil by incorporating a soil conditioner like garden compost or manure.
- Sprinkle general-purpose fertilizer, as directed on the pack, into the area where you plan to plant it, such as Growmore, Vitax Q4, or blood, fish, and bones.
- Before planting, water your plants thoroughly to hydrate the roots.
- Remove pots from larger plants and ease seedlings out of modules or pots while being careful not to snap or crush the stems.
- Plants should be separated by 20–30 cm (8–1 ft).
- Place climbing plants near to their intended support (within 5-7.5cm or 2-3in), with two plants at the foot of each cane if they are climbing a wigwam.
- After planting, water once more to help the soil surrounding the roots settle.
Use garden twine or sweet pea support rings to secure young climbing plant shoots to canes, pea sticks, netting, trellis, or shrub shoots that they will be growing up. Tendrils in contact with supports will naturally start to cling on, but if any are straying or in danger of snapping, keep tying in new shoots.
In dry weather, check on plants in the ground every 3 to 4 days and on those in containers every day because they won’t flower as well if they become too dry. Each time you water, be sure to use enough water to completely moisten the roots.
Apply a high potassium liquid fertilizer, such as tomato feed, once or twice a week on light or infertile soils. This promotes flowering, particularly in annual sweet peas (Lathyrus odoratus).
Pick or remove dead flower heads as frequently as you can once flowering starts. For annual sweet peas (Lathyrus odoratus), which will stop flowering if seedpods are allowed to form, this is especially crucial.
Pinching out
When plants are around 7.5 to 10 cm tall, pinch out the shoot tips of new spring-sown sweet peas for gardening (3-4in). This promotes robust side branching. Autumn-planted seedlings frequently naturally branch.
Cordons
Pick the strongest shoot and keep pinching out all the tendrils and other sideshoots as they grow whether you want to enter your sweet peas in a local show or just want to maximize the size of blossoms for cutting. By using this technique, the plant directs its attention to the blossoms. The term “cordons” is used to describe these single-stemmed plants.
One stem per bamboo cane or tall stake needs to be tied to them on a regular basis. To keep the shoot in place as it grows, you can use twine looped in a figure-eight pattern around the cane and stem. Use sweet pea rings, which are wire loops that wrap around the stem and cane and are lightly squeezed until they hold, to make things simpler.
Cordons have the potential to grow much taller than the typical 2 m (6 1/2 ft) estimated height.
Cutting back
Cut perennial Lathyrus back to the ground in the fall, or better still, wait until February to do it so the dead stems can serve as wintertime cover for wildlife. When flowering is ended at the end of the summer, annual sweet peas can simply be pulled out and composted. This might happen a little bit sooner during hot, dry seasons.
Methods
Sweet peas can be immediately sown into the ground in April, or they can be planted in seed compost pots in the fall or spring. Although it takes more time, pot-sowing is typically more dependable than direct sowing. If you plant in the fall to enhance your chances of getting early blooms, keep seedlings in a coldframe or cold greenhouse over the winter to protect them from growing lanky. Keep the coldframe’s lid elevated unless a strong frost is anticipated. Sweet peas planted in the spring flower in 12–14 weeks.
Sweet pea seeds frequently have a tough outer covering that makes them more challenging to germinate. Place your seeds on a layer of damp vermiculite or kitchen tissue and store them in an airtight container in a warm area. As soon as the seeds swell or start to sprout, plant them. Some gardeners like to soak the seeds overnight instead, but if you don’t plant them right away thereafter, they might rot. With a sharp penknife, chip off a little portion of the hard seed coat to allow moisture to enter and promote germination on recalcitrant seeds that haven’t swelled.
- Individually sow seeds in seed compost-filled rootrainers or 9 cm (3 in) pots. As an alternative, sow five to seven seeds per 13 cm (5 in) pot, spacing them 2-3 cm (3/4-11/4 in) apart.
- Add 1 cm (1/2 in) of vermiculite or compost to the top of the seeds.
- Add water and maintain at around 15C. (59F)
- It is optional to cover the pots with clear polythene or glass to reduce the likelihood that they will dry out, but keep in mind to remove the covering after the seeds have germinated.
- Once they have grown to around 3.5 cm (11/2 in), carefully transplant single seedlings into 9cm (3 in) pots if you have seeded them several to a pot.
- Use your thumb and finger to pinch out (remove) the top of the shoot just above a healthy leaf when the seedlings are 7.5–10cm (3–4in) tall. This will promote side branches, which are always stronger than the core stem that has been removed.
- At least four weeks before planting, remove all weeds from the soil and add a soil enhancer, such as garden compost, manure, or composted bark.
- Only plant seeds as the soil begins to warm, typically around April.
- To create a wigwam, plant any temporary supports, like pea sticks or bamboo canes, in the ground.
- Take out a shallow drill of dirt 2.5 cm (1 in) deep for rows of sweet peas, and plant a seed every 5 to 7.5 cm in it (2-3in)
- Seedlings should eventually be spaced 20–30 cm (8–1 ft) apart to provide the plants enough room to flourish. The extra seedlings may seem like a waste to compost, but unless treated carefully, their roots are typically too damaged to recover.
- Push two seeds into the ground at the base of each cane to a depth of 2.5 cm (1 in) when sowing around a wigwam of canes.
Perennial peas
In the spring or the fall, divide bigger plants. If you want to divide Lathyrus vernus in the spring, wait until after flowering.
Unfortunately, very few of the issues with sweet peas and perennial peas are extremely problematic.
- Powdery mildew, which is brought on by drought or insufficient hydration, results in a grey leaf coating.
