Although Lathyrus odoratus, the most popular sweet pea variety, is an annual, there are also perennial forms available (Lathyrus latifolius).
- 1. Annual sweet peas are plants that go through their entire life cycle in a single growing season. They grow, produce seeds, and perish within the span of a year, just like other annual crops. The next year, you must replant new plants in your garden if you want to grow them again. The majority of sweet pea species are annuals.
- 2. Perennial sweet peas: These flowers reappear each year. After the growth season is over, you don’t need to replant them because they will keep growing for a longer period of time. Although there are fewer types of perennial sweet peas available and they tend to lack the traditional sweet pea aroma, they may be simpler to grow.
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.
ARE SWEET PEAS ANNUALS?
Lathyrus odoratus, a lovely and flouncy annual sweet pea, can be grown from seed every year for its fragrance and for cutting. You can climb it over obelisks or other slender supports in borders or a cutting garden.
Peas are either annual or perennial.
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.
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.
Will sweet peas re-grow the next year?
Heirloom or old-fashioned sweet peas are lovely and aromatic blossoms. Pick an heirloom variety if you want to save seeds. Modern hybrid seeds could be disappointing because they won’t likely resemble the parent plants.
You don’t need to go to the trouble of saving seeds if you intend to grow sweet peas in the same garden location again the following year. The seed pods rupture when they dry, dispersing their contents to the ground. These seeds will produce blossoms during the next year. However, use these simple steps to gather the seeds if you wish to plant them somewhere else or share your supply with a friend.
Stop deadheading a select few strong, lovely plants. The blossoms must stay on the plant until they are dead since seedpod formation doesn’t start until after the flower has died. The rest of the garden’s plants should be cared for as usual, with deadheading to ensure continuous spring flowering.
Sweet peas can they be grown in pots?
Sweet peas can be grown in pots with great success as long as a few simple guidelines are followed. which are

- Keep well-hydrated. Every day that it does not rain, make sure there is good drainage from the container and water. When plants develop
When fully grown, watering could be required even when it’s raining because the foliage diverts the water from the container.

- 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.
Are sweet peas cold-resistant?
According to Gardeners’ World (opens in new tab), sweet peas should be treated like any other non-hardy annual: “Plant your sweet peas outside starting in late May, after all danger of frost has passed. Put them outside throughout the day and bring them inside at night to harden them off before planting.
The most recent edition of Sarah Raven’s podcast (opens in new tab) claims, however, that “Sweet peas are hardy and can go in the garden from the middle of March.”
Confused? So were we up till we learned the RHS’s excellent sweetpea-growing tips (opens in new tab) (watch in the video above). Sweet peas are in fact “extremely tough,” says Propagation Leader Sam Gallivan, and they can withstand frosts “with no issue at all.” They do struggle with extended cold and rainy times, though. Your young sweet pea plants could perish if you reside in a region where early spring can bring both low temperatures just above freezing and a lot of rain.
Because of this, you have two options: either hold off and plant them outside in April when the weather will be warmer, even if it rains, or keep them in a cold frame until the chilly showers stop. However, sweet peas are typically categorized as half-hardy annuals and can withstand dry frost up to -4C. (25F). You will need to cover them with horticultural fleece in the event that temps fall below that.
How are sweet peas pruned?
As soon as the ground can be handled, sweet pea seeds can be planted immediately into thoroughly loosened soil. The seedlings of peas should be thinned to a distance of 5 to 6 inches (12.5 to 15 cm) apart once they have sprouted to a height of 3 to 4 inches (7.5 to 10 cm). Wait until sweet pea plants are 4 to 8 inches (10 to 20.5 cm) high before pinching them. Use your nail as a blade to snip off the growing tip that is located between your forefinger and thumbnail. The plant hormones known as auxins will be forced to the side or auxiliary tips of sweet peas by pinching them out. The auxins will result in expansion and the development of new, stronger growing tips.
Sweet peas can be pinched out to produce more blossoms for cutting. One of the wonders of raising these lovely vines is that. Don’t be hesitant to pinch out your sweet peas to enjoy the bouquets since the more flowers you cut, the more will grow.
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.
