Since they don’t need a set length of day to start flowering, perennial sweet peas (Lathyrus latifolius) can grow year after year in USDA zone 38 and flower in mild weather from spring to fall.
How long till a sweet pea flowers?
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.

When does the sweet pea bloom?
Depending on where you live and how hot your summers get will determine when the sweet pea (Lathyrus odoratus) flowers. With their fragrant pea-like flowers blossoming in a variety of colors, these annual climbers are eye-catching additions to containers or outdoor spaces. Success is ensured by planting at the appropriate time of year for your locality.
Tip
Depending on where you live, the sweet pea flowering season happens during several seasons. Flowers will bloom in the late spring and into the fall in regions with cooler summer temperatures. Those who reside in warmer climates can look forward to flowers in the winter and spring.
Exactly why aren’t my sweet peas blooming?
The three things we’ve talked about can all be corrected, although deadheading is the most straightforward. Once you start deadheading neglected plants, you’ll be astonished at how quickly you’ll start seeing blossoms.
You can move your sweet peas to a spot with more sunlight if the lack of light is the reason of their inability to blossom. But keep in mind that transplanting sweet peas in hot weather is not recommended. In fact, once the temperatures rise, they frequently begin to die back.
It is more difficult to get sweet peas to blossom after fertilizing with high nitrogen fertilizer. Nothing you can add to the soil will totally solve the issue, however adding a high phosphorus fertilizer or bone meal can make a small difference. Watering them as frequently as you can might also be beneficial. Just take care to prevent them from getting wet or waterlogged.
How much time do peas need to flower?
- Frost damages pea blooms and prevents the development of pods. Check the optimal sowing period for your region’s climate.
- For the greatest results, I sow during the first moon quarter of the month to take advantage of the soil’s wetness and an active development period for peas and other above-ground plants.
- I personally wait to plant seedlings and instead sow seeds if the humidity is higher than 70% and the temperature is still high. I’m hoping the weather will be better when they are prepared.
- Peas take between 10 and 14 weeks to mature, blossom, and produce fruit, depending on the type. Peas can mature from bloom to pod in up to 3 weeks.
A younger climbing type of sugar snap pea bears blooms. Peas require a trellis or staking as they grow to provide support.
When requesting “quick food”:
- You don’t have to wait for the pods to fill when you choose snow peas. Excellent option for young people and impatient gardeners!
Are sweet peas water-intensive plants?
If you pinch out the growth point while immature sweet peas are in the seedling stage, whether you sow them in the spring or the fall, they will sprout more branches that will bear blossoms.
I examine sweet pea maintenance in the video, focusing on how to remove the growth point. The video demonstrates how to reduce the sweet pea’s growth point to encourage it to produce more shoots, which will increase the number of summer flowering stems.
The following photos:
- The young sweet peas in the first photograph already have a few early leaves.
- Secateurs to indicate the location of the growth point removal.
- The full tray of seedlings with each seedling’s top growth point removed can be seen in the center image.
- The single stem is no longer present in the third photograph, which was shot about 10–14 days later, and there is now a side branch.
Once planted, they require constant watering if the summer is dry since sweet peas detest being dry because it makes them susceptible to mildew.
It’s also important to get rid of any tendrils in order to keep them straight and attractive.
It takes an hour or more once or twice a week at the height of summer to grow the 50 or so plants that make up a beautiful display, which makes for heavy upkeep.
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.
How long does it take sweet peas to grow?
The fragrant, sweet aroma that is released by the blossoms of annual sweet peas (Lathyrus odoratus) gives them their name. The fall, winter, and early spring garden seasons in warm, Mediterranean settings are perfect for this annual flowering vine because it prefers mild temperatures. In the spring and early summer, sweet peas grow best. Plant hardiness zones 4 through 7 of the United States Department of Agriculture are suitable for perennial sweet peas (Lathyrus latifolia). Depending on the cultivar, sweet pea blossoms come in a variety of hues, including white, purple, pink, red, orange, blue, and lavender.
Depending on the species and cultivar, it can take sweet peas 90 to 120 days from seed sowing to start flowering.
