Yes, sweet peas can come back every year.
There are both annual and perennial varieties of sweet peas.

Did You Know?
1. Sweet peas are known for their fragrant, beautiful flowers, but did you know that they are actually members of the legume family? These delicate flowers are closely related to plants such as beans and lentils!
2. Sweet peas are not perennial plants, meaning they do not come back every year on their own. They are actually annuals, which means they complete their life cycle within a year. However, with proper care and maintenance, they can reseed themselves and appear to come back in subsequent years.
3. Sweet peas were first discovered in Sicily in the 17th century. They were later brought to England, where their popularity quickly grew due to their enchanting fragrance and vibrant colors. Today, sweet peas remain widely adored by gardeners and florists around the world.
4. Sweet peas come in a wide array of colors, including shades of white, pink, purple, and blue. However, the color that is truly elusive in sweet peas is yellow. Despite numerous attempts by breeders, a true yellow sweet pea has never been successfully developed.
5. Sweet peas have a rather curious historical connection with Queen Victoria of England. It is said that she loved sweet peas so much that she had a special conservatory built at Osborne House to grow them. She even started a tradition of wearing a bouquet of sweet peas on her wedding anniversary each year.
Annual Vs. Perennial Sweet Peas
Sweet peas are captivating flowers that can be classified as either annual or perennial. Annual sweet peas complete their life cycle within a year, providing a burst of color and fragrance to the garden for a single season. These varieties are highly fragrant and produce an abundance of blooms from spring until the end of summer.
On the other hand, perennial sweet peas have the remarkable ability to return every year, bringing delight to garden enthusiasts. As the temperatures warm and spring arrives, these reliable perennials burst forth with new growth and a profusion of delicate flowers. Their consistent presence adds a touch of reliability to any garden.
Fragrance And Lifespan Of Annual Sweet Peas
The captivating fragrance of sweet peas is one of their most beloved characteristics. When it comes to annual sweet peas, this scent is particularly pronounced. Although these flowers grace the garden for just one season, their intense fragrance permeates the air, enticing pollinators and humans alike.
The lifespan of annual sweet peas may be short, but their impact is undeniable. With proper care and attention, gardeners can enjoy a spectacular display of fragrant blossoms that will continue to enchant throughout the season.
The Return Of Perennial Sweet Peas
Unlike their annual counterparts, perennial sweet peas have the remarkable ability to grace our gardens year after year. These steadfast blooms are known to re-emerge each spring, bringing joy and splendor to the landscape.
Gardeners who choose to cultivate perennial sweet peas can look forward to a reliable and perennially pleasant addition to their gardens. These resilient flowers will resurface with vigor and grace after the cold winter months, heralding the arrival of spring and offering a welcome burst of color.
Benefits of cultivating perennial sweet peas include:
- Long-lasting blooms: Perennial sweet peas provide continuous beauty throughout the years, ensuring a stunning display in the garden.
- Low maintenance: These flowers are relatively low maintenance, requiring minimal care and attention.
- Increased garden biodiversity: By planting perennial sweet peas, gardeners can attract a variety of pollinators, contributing to a thriving ecosystem.
- Cost-effective: As perennial sweet peas come back year after year, there is no need for repeated purchase or replanting, resulting in cost savings over time.
Perennial sweet peas are truly an enchanting addition to any garden, offering beauty and resilience that will endure for years to come.
“The presence of perennial sweet peas in the garden is a testament to nature’s enduring cycles and the beauty they bring.”
Differences In Scent And Growth Pattern
While annual sweet peas have a stronger and more intoxicating fragrance, perennial sweet peas possess a more delicate scent. Though not as potent, the gentle sweetness of perennial sweet peas still brings delight to the garden. Moreover, perennial sweet peas differ in their growth pattern from their climbing annual counterparts. Whereas annual sweet peas are climbing vines, perennial varieties may take on a bushier form. This variation in growth habit adds diversity to the visual appeal and practicality of sweet pea cultivation.
Tips For Growing And Supporting Sweet Peas
Successfully growing and supporting sweet peas requires a combination of proper care and appropriate garden structures. To ensure their growth is strong and vibrant, pinching out the tips at around 10 centimeters encourages the development of flowering side shoots for spring-sown sweet peas. However, this practice is unnecessary for autumn-sown plants.
When planting sweet peas seedlings or plugs outdoors, they should be hardened off before being placed in a sunny and open location with well-drained, fertile soil. Supporting structures such as trellises, netting, canes, obelisks, or garden arches are essential to help sweet peas climb and flourish.
For those cultivating sweet peas in pots, slow-release fertilizer can be added to the compost during planting. Once they begin blooming, regular feeding with tomato fertilizer promotes healthy growth and abundant flower production. To enjoy a continuous supply of blooms, regular harvesting of sweet peas is recommended, as this stimulates more flowers to develop.
sweet peas can be both annual and perennial plants. While annual sweet peas provide an intense fragrance and last for one season, perennial sweet peas bring their delightful presence back to the garden each year. Understanding the differences in scent, growth pattern, and care requirements allows gardeners to cultivate these lovely flowers successfully. With their captivating fragrance, vibrant colors, and graceful ascent, sweet peas are a delightful addition to any garden.

Frequently Asked Questions
How do I know if my sweet pea is annual or perennial?
To determine if your sweet pea is annual or perennial, you can observe its flowering pattern and fragrance. Annual sweet pea flowers, known as Lathyrus odoratus, typically bloom vigorously for one season and need to be freshly sown each year. These annual climbers often exude a strong and delightful fragrance. On the other hand, perennial sweet pea flowers, called Lathyrus latifolius, return reliably every spring. While they lack the same intense aroma as their annual counterparts, their resiliency and ability to reappear year after year make them a charming addition to any garden.
How many times can you harvest sweet peas?
To ensure continuous blooming of sweet peas, it is essential to harvest the blooms at least twice a week. By doing so, you not only enjoy a consistent supply of beautiful flowers but also encourage the plant to keep producing more blooms. Failure to harvest regularly will result in the plant diverting its energy towards seed production, subsequently ceasing flowering altogether.
Is sweet pea a hardy annual?
Despite its delicate appearance, sweet pea is considered a hardy annual. This means that it can withstand frosty conditions, including temperatures as low as minus 5 degrees Celsius, making it an ideal choice for autumn planting. While its flowers may be fragile and short-lived, the sweet pea plant itself has a surprising resilience that allows it to thrive in colder weather.
How many years will sweet pea seeds last?
Sweet pea seeds have a relatively short lifespan of around two to three years if they are stored correctly. To ensure their viability, it is essential to allow the pods to fully mature on the vine before picking them. Once harvested, the seeds should be left to dry out before being stored in a suitable container. By following these simple steps, you can maximize the longevity of sweet pea seeds and enjoy their beauty in your garden for years to come.
