Award-winner Lathyrus latifolius, sometimes known as perennial or everlasting pea, Sweet Pea is a robust climbing perennial that produces racemes of 5–11 colorful, pea-like blooms that range in color from rose to white and measure 1 in (2.5 cm). If not allowed to grow to seed, the lovely blossoms, which bloom all summer long, are carried on winged stalks covered in paired, tendril-bearing blue-green leaflets. They will wander about the ground or scale surrounding supports or vegetation. The blossoms of Everlasting Peas are not scented, in contrast to Lathyrus odoratus. Lathyrus latifolius is simple to cultivate, needs little maintenance, and can withstand some drought.
Everlasting peas are native to the Mediterranean region, but since they were introduced to North America in the 1700s, they have naturalized to the point where some people now consider them to be invasive.

The perennial sweet pea (L. latifolius), which clogs open fields and roadside vegetation, is an invasive pest in many parts of North America. Before you understand it’s displacing other plants and acting like a thug, it appears to be rather attractive.

When between October and April, plant sweet pea seeds. Aim for late October or late November or late February or early March for the best outcomes because midwinter temperatures and light conditions aren’t the optimum. In April or May, sweet peas can also be planted directly into the ground. During a moderate period between March and May, sow your sweet pea seeds and plants.
What is the name of the perennial sweet pea?
As you can see from the pictures, the annual climbing pea and the perennial variety of the annual sweet pea are extremely similar in appearance. Its Latin name, Lathyrus latifolius, contrasts with the annual sweet pea’s Latin name, Lathyrus odoratus, which emphasizes the key distinction between the two peas. Few everlasting peas contain perfume, compared to the majority of annual sweet peas.
The nonscented types of Everlasting Pea plants are often those that are for sale. Everlasting pea seeds come in roughly 20 different types.

Do I need to trim back my perennial sweet peas?
I have a beautiful sweet pea vine that has grown up the chain link fence and is covered in many pink and white blossoms. What maintenance should I give it over the winter? Must the vine be removed from the fence?
Although there are annual forms, perennial sweet peas are hardy in zones 4 to 8 and require little assistance to survive the winter in these regions. To boost hardiness, leave healthy plants standing over the winter. Before the plants start to grow, prune them back to the ground in late winter or early spring. In the fall, cut back sickly sweet pea plants to the ground. To lessen the chance of more disease issues, throw away the leaves and stems of sick plants rather than composting them.
How tall can you grow perennial sweet peas?
More hybrid vigor than any of the current annual sweet peas can be found in this much-ignored yet valuable garden plant.
These swiftly develop to a height of 6 to 8 feet (1.8 to 2.4 meters) and can be trained over an archway, up against a trellis, fence, or sunny wall, as was so common in Victorian England. They can also be planted over a flower cage.
You can also grow plants in balcony pots or tubs to have them flow in bloom like a waterfall of leaves. A good, rich loam works well for these. Throughout the summer, they bloom in colors of deep rose pink, white, and purple rose and are superb as cut flowers. The one minor negative about these lovely blossoms is that, in contrast to perennial Sweet Peas, they have very little perfume.
The RHS recommends this plant as a great honey supply and attractant for bees and other beneficial insects.

Why do people grow Sweet Peas?

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.
