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.
Sweet peas can they endure the winter?
Growing Sweet Peas To survive the winter, fall-planted sweet peas should be housed in a cold frame or greenhouse. Although seedlings shouldn’t be coddled excessively (cold temperatures will make plants stocky and strong), they won’t like being repeatedly chilled, so provide additional protection in frosty weather.
When do sweet peas bloom?
I grew up spending a lot of time with my great-grandparents and summers in the country. I had the responsibility of keeping fresh flowers on my Grammy’s nightstand. She had many lovely flowers blooming in her garden, but the one I most vividly recall is the tangle of rainbow-colored sweet peas clinging to the posts of her carport.
I immediately planted a giant tunnel of sweet peas in the middle of the garden after we purchased our first home. I was transported back in time to the summers of my youth and the pleasant recollections of collecting flowers in Grammy’s garden as the first blooms bloomed that spring.
I’ve grown and tested close to a hundred different sweet pea varieties over the years, including both heirloom and hybrid varieties, in a number of studies I’ve carried out over the years. Even while they have all been lovely, I do have a few favorites and a small number of them that I simply cannot live without.
Sweet peas can be planted in the fall in warmer climates (zones 7 and higher), where the winters are generally not too harsh. Other than that, plant seeds in late winter or early spring.
Before planting, give the seeds a 24-hour soak in water. By doing so, the seed coat is softer and the sprouting process is accelerated. See our resource, How to Grow Sweet Peas, for further information on seed sowing.
It might be challenging to keep up with the harvest once the vines start to produce blossoms. To catch blooms at their peak, I comb the rows every other morning.
Choose stems with at least two unopened flowers at the tip for the best vase life. Although they can be chosen when more open, they won’t last as long in the vase. Sweet peas only endure 4 to 5 days in a vase, making them a transient cut flower. A few extra days can be added by sweetening the water or adding a floral preservative.
Please be aware that sweet pea seeds are toxic if consumed, unlike garden pea seeds. Be cautious when around kids and animals.

Do sweet peas continue to grow?
One of the most well-liked flowers for cottage gardens is the sweet pea, which is admired for both its lovely blooms and delightful aroma. They provide a stunning column of fragrant, summer color in beds and borders when trained onto a plant structure in the shape of a wigwam. Sweet peas are simple to grow and make wonderful cut flowers; the more you harvest, the more they will grow.
The sweet pea comes in two varieties. Annuals only last for one season, but kinds of everlasting perennials come back year after year with far less fragrant flowers. Read on for our helpful guidance on how and when to plant sweet pea seeds.
Can pea plants regrow?
When your pea plants reach a height of 6 to 8 inches, cut off the top growth, including the first set of leaves. Your first modest harvest will be this one. By removing the plant’s growing tip, you can urge it to continue to spread its roots and produce more shoots and tendrils.
The top 2- to 6-inches of the pea plants can then be harvested every three to four weeks after that. Shoots, leaves, and tendrils can be harvested, as well as any buds or flowers that may have grown.
As the season progresses, you will start to notice that the shoots are not as soft as they were earlier on, and the flavor is beginning to become bitter. This indicates that it’s time to end the harvest. On these plants, you might notice pea pods developing if the temperature stays chilly. However, it is likely that the pea season will end before that.
You can’t rely on getting a fresh harvest of pea shoots and tendrils in the fall if you let the plants develop and then cut them back to about 4 inches in late July, according to some gardeners. Before then, it is more likely that the plants may perish from insects or the dry heat. You will need to reseed at the end of the summer and hope for a long, cool fall if you want a harvest in the fall.
Will 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.
What are some wintertime uses for sweet peas?
Sweet peas planted in the fall should be kept in a cold frame or greenhouse for the winter. Although seedlings shouldn’t be coddled excessively (cold temperatures will make plants stocky and strong), they won’t like being repeatedly chilled, so provide additional protection in frosty weather.
How to sow sweet pea seeds
Sweet pea flower seeds are frequently advised to be nicked or chipped before planting, as well as to soak in water or damp paper towels for the night, although none of these steps are necessary. Sweet peas thrive in root trainers, which are unique tall plug trays, or 9cm pots since they prefer to have a long root run. But a toilet paper roll’s cardboard interior will also work.
Individual seeds can be sown in toilet paper inners or root trainers, or two to three seeds can be planted in a 9 cm pot. The container should be filled with seed compost, dampened, and then the seed should be pushed in with your finger to a depth of about 1 cm. Add some compost to the top and gradually water. Put the pots in a protected area that is well-lit. Unlike other seeds, they do not require additional heat from a propagator. When the seedlings emerge, place the pots somewhere sunny and cold, ideally between 5 and 10 degrees Celsius, or else they will grow long and lanky.
What month do you plant sweet peas?
Sweet peas can be purchased as plug plants or are produced from seed. If starting from seeds, you can plant them in the spring (February to April) or the autumn (usually October or November), and then nurture the seedlings into little plants.
Autumn and early spring seeds require a frost-free environment to thrive, such as a cold greenhouse or cold frame. It is better to wait and plant the seed later, in April, when you can start them off easily on a windowsill inside, if you don’t have a place that is cool and light like this. Alternately, in late April and early May, direct-sow outdoors in larger pots or the ground.

How to grow and care for sweet pea flowers
When your sweet pea seedlings are about 10 cm tall after spring sowing, you can pinch out the tips to help them develop into vigorous, bushy plants with lots of flowering side shoots. Just above a pair of leaves, place the growing point at the top of the stem between your finger and thumb, squeeze it, and snip it off. Avoid pinching the tips of plants seeded in the fall.
Prepare your seedlings and plugs for growing outdoors by hardening them off after there is no possibility of frost, often starting in late May. To help them get acclimated to the cooler weather, this entails leaving them outside during the day and bringing them inside at night for about a week.
Their final growing location should be in a sunny, open area with fertile soil that has good drainage. Because they climb, annual sweet peas require a support to develop. trellis, netting, a cane teepee, a border obelisk, or a garden arch are typical examples. Plant the sweet peas 15-20 cm apart, 5 cm from the base of the support you’ve chosen.
If grown in pots, plant the compost with some slow-release fertilizer to keep the plants healthy all season. Keep the plants well-watered and keep an eye out for slug and snail damage.
Sweet pea blossoms should be secured to their support as they enlarge using garden twine or support rings. Once the sweet pea blooms begin to bloom, routinely treat them with tomato fertilizer. Continue picking flowers throughout the summer because the more you pick, the more are generated.
Do sweet peas come back every year?
Sweet pea blooms come in annual and perennial varieties. Lathyrus odoratus, an annual plant that must be sown from seed every year, is typically a climber with a strong fragrance. Every spring, the perennial or “everlasting” varieties of Lathyrus latifolius reappear, however the majority of them have little or no perfume. Some don’t climb; they are bushy.
