Although Lathyrus odoratus, the most popular sweet pea variety, is an annual, there are also perennial forms available (Lathyrus latifolius). Annual sweet peas: During a single growing season, annual sweet peas go through the entire life cycle.
Do peas grow as annuals or perennials?
The majority of legumes produced in backyard gardens, such as beans and peas, are annual plants, meaning they go through their entire life cycle in a single year. On the other side, perennial legumes are ones that can survive for more than two years.
Sweet peas: perennial or annual?
Sweet peas are quite popular, but fresh plants must be grown from seed every year. These are their vibrant cousins—perennials that flower all summer long every summer and grow cheerfully along trellises or clamber through shrubs.

Do sweet peas reproduce on their own?
Although sweet peas can be grown in pots or hanging baskets, a larger in-ground growing area is typically preferable. These plants want lots of space both in breadth and depth because the size of the blossoms is inversely proportional to the size of the roots.
It is advised to use containers that are at least 18 inches deep because lesser sizes can stunt growth. Use smaller containers if you don’t care about this. In either case, the blossoms are lovely. Just make sure to water them regularly to prevent drying out.
Look for sweet pea seeds that are advertised as being suitable for container growth.
In a warmer climate, yes. It is definitely feasible for some sweet pea plants to self-seed the next year if you allow them to go to seed in the fall and let the seed pods burst open and release the seeds. This is known to occur in zones 7 or warmer. If the seed does not freeze throughout the winter, it might also occur in regions with lower temperatures.
With pinching back (selectively removing the tips of major stems) and deadheading (removing dead blooms and their stalks), sweet peas will grow more profusely, although it’s completely optional.
At the time of planting, install the trellis or arch. Make sure the plants are getting hold of the supports and nicely covering the trellis by checking on them every few days.
Yes. Pods will develop once the blooms have finished blooming. These pods will contain seedlings. When they are brown and dried and the pods are just beginning to open, they are suitable for harvesting.
Yes. The secret is to select sweet peas when the blossoms at the stem’s top are still closed. Make a precise incision through the stem. Put the freshly cut flower right into a vase filled with room temperature water and cut flower preserver. In a vase, they typically last for 4 to 5 days.
How old are sweet peas?
To make those cut sweet pea flowers endure as long as possible in the vase, some management is required. Provide clean water every day to provide the flowers the minerals and moisture they need to be healthy.
Each stem can be periodically trimmed by 1/4 inch to encourage the flower to continue drinking water for a longer amount of time and prolong bloom time. Cut sweet peas can look stunning for up to a week if you take care of them.
spring
- From March to May, you can easily plant your young sweet pea plants outside. Before planting out, sweet pea seeds sown in the winter or autumn need to be potted up into larger containers. Spring-sown seeds can be transplanted from their rootrainers.
summer
- Pick your sweet peas, then put them in indoor vases. Remove the seed pods from your sweet peas to continue deadheading them. You’ll need to harvest and deadhead them frequently when they’re at their height.
Are sweet peas resilient?
Sweet peas are a robust annual, so they can withstand cold temperatures, including a light frost if it is below freezing. They can withstand a regular cold down to about -4 degrees and are tougher than they appear. Sweet peas only need to be protected, such as with a fleece, if a heavy frost or extended period of low temperatures is predicted.
Do not wait until it is too late to grow sweet peas because they are hardy. Sweet peas can be sown beginning in March. The sweet peas grow best when tied to a structure, like a trellis or an obelisk.
Remove the tendrils and don’t allow them grow unchecked if you want straight stems and sweet peas that grow up the frame rather than a tangled clump. Why? See how to give sweet peas straight stems.
Don’t let the seed head form; keep plucking sweet peas. Check at the picture where the seed pod is ringed in red if you have any questions about seed pods. The sweet pea will reward you with increasingly more blossoms if you remove all seed heads as they develop.
What are some wintertime uses for sweet peas?
Sweet peas can endure nighttime lows of about -5, but they do not enjoy being kept in frozen pots all day. In the event that you go overboard and kill the top growth, there’s a good chance that if you give them some warmth, they’ll have developed enough roots to sprout anew.
Do sweet pea pods need to 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.
How should a sweet pea plant be cared for?
In long pots filled with a quality seed-sowing compost, sow seeds in March or April for the greatest results. In 9cm (3.5in) pots, sow seeds one at a time, or in 12.5cm (5in) pots, sow 5-7 seeds at a time. at roughly 15C, germinate and develop on the plants (60F). If many seeds are placed in a container, transplant each seedling into a 9cm (3.5in) pot when it is about 5cm (2in) tall.
In March, April, or even May, you can plant seeds directly in the ground, but the results won’t often be as good. In milder climates, you can also plant seeds in containers in October or November, and the young plants can spend the winter inside a cold frame or unheated greenhouse. The plants that result from this will flower earlier the next year.
Some kinds may be challenging to germinate because their seed coats are hard. It’s not always required to follow the recommendation to use a sharp knife to chip away a portion of the tough seed coat to aid germination. If you want to give it a shot, make a little nick on the side that is not the “eye.” Do not soak the seeds in water as this could cause them to decay.
How to care for sweetpeas
Pinch out the growth tips of plants when they are 7.5–10 cm (3–4 in) high to promote branching, bushier plants, and more flowers.
After first hardening them off, plant the overwintered plants in mid-spring and the spring-sown ones in late-spring or early-summer. It might be best to hold off until after the last spring frost because the plants might need protection from cold and late frosts. Plant at a distance of 8 to 20 cm.
Water the plants well to help them settle in after planting, and then again if it gets dry.
Regularly feeding plants with a liquid feed strong in potash throughout the summer will encourage ongoing flowering.
When blossoms are ready, cut them as often as possible, preferably before they fade and start to form seed pods. If not, they will stop blooming.
Are sweet peas trellis-required?
One of the best plants for cutting, sweet peas (officially known as Lathyrus odoratus) offer tempting colors and aroma for spring and early summer bouquets. The tiny flowers emit a grape-like fragrance into the air and come in a variety of beautiful colors. We enlisted the assistance of Barb Pierson, our nursery manager, to provide some guidance for individuals who have never grown Sweet Peas in a garden or a container pot. Any beginner or green thumb can benefit from a plentiful supply of these lovely flowers thanks to her advice.
Why do people grow Sweet Peas?
Sweet peas are cultivated for their lovely, ruffled blossoms, which come in pastel, blue, and bicolor hues. They are a beautiful cut flower since many types have scented blooms. The cultivation and breeding of sweet peas for both the home grower and the florist industry has a long history.
How do I go about growing Sweet Peas?
Sweet peas can be grown from seed that is treated before sowing or, more conveniently, from a starting plant. At White Flower Farm, we plant three seeds in each pot to create three Sweet Pea vines.
Where do I plant them and when?
In the northern half of the US, sweet peas flourish in the full sun. They can benefit from afternoon shade in the South. They are planted as early as possible in the spring since they prefer mild temperatures and cool roots. Newly planted seedlings will not be harmed by a mild cold. They can be sown in the fall and cultivated through the winter and early spring in highly warm climates. Compost should be added to the soil, and the area should be well-drained for optimal results. Sweet peas can be successfully grown in raised beds.
Do they need any special care while they are growing?
Sweet peas require support to grow and flower because they are climbing plants. Many other kinds of structures, like a trellis, supports made of mesh or wire, or fences, can be used. To sustain the weight of the vines, they require a sturdy framework that is firmly planted in the ground. The vegetation will develop tendrils that encircle the support you offer.
Since they like nutrient-rich soil, adding compost at planting time is advised. Mulching Sweet Peas will keep the roots cool and help them retain moisture as they grow.
Pinch the growth tips by one after the plants have reached a height of around six to encourage branching and the development of extra flowering stems.
What are the most common mistakes that people make with Sweet Peas?
- planting them in the middle of the summer They dislike the heat and won’t blossom as frequently.
- not offering assistance when planting. Once the plants have begun to grow, it is challenging to install your trellis or support.
- Lack of compost or fertilizer will cause weak plants and fewer flowers in poor soil.
- If Sweet Peas are planted too closely together without being thinned out, powdery mildew can grow and crowding lowers bloom production.
Do Sweet Peas produce pods that you can eat like the ones you find in the grocery store?
Despite having the appearance of snap pea pods, the seed pods are not edible. The pods and seeds can be saved in order to grow plants the following year. Remember that the plants that the seeds may grow may not be the same hue as the parent plant.
Will the plants come back again next year?
The plants are typically not winter hardy in most areas. They are replanted with new seed and plants even in warm climates to produce the most flowers and have robust development.
When do they bloom? Are there tips for getting extra blossoms?
Sweet peas will begin to blossom 4 to 6 weeks after they begin to show apparent vining. Whether or not the plants have been pulled back will affect the timing of the bloom. Although pinching may slightly limit growth, it will result in bushier plants with more flowers. In the spring and early summer, sweet peas will grow and bloom more quickly as the days lengthen. Compost or old dry manure can aid to supply nutrients for the growth of huge, many blooms. A fertilizer with a phosphorus to nitrogen ratio greater than one can also increase flower production.
What is the process for cutting the blooms?
Cut the blossoms early in the day to prevent the sun from drying them off. For your vase, select newly opened flowers with the longest stems. Just the side flowering stems of the plant should be clipped; leave the main stem alone.
Why should I get my Sweet Peas from White Flower Farm?

Can I gather sweet pea seeds?
As soon as the sweet peas’ brittle, brown shells appear, start preserving the seeds. Sweet pea seedpods won’t germinate if you harvest them before they are fully developed. However, if you wait too long, the fragile seed pods will crack open and scatter their seeds all over the place. The procedure may take a few weeks, so keep an eye on them. You need to immediately pluck the pods if they start to split.
Sweet pea seeds are simple to collect. Remove the seeds from the seedpods and bring the plant inside. The seeds should dry for about three days on a level surface, such as a countertop or baking sheet, lined with newspaper. Once they are dry, store them to maintain their dryness in a freezer bag or Mason jar with a tight-fitting lid. Before planting, keep them in a cool location.
