About Sweet Pea Flowers

About Sweet Pea Flowers

Sweet pea has a long history in gardening and floral design. Due to its easy cultivation, distinctive colors, and wonderful scent, it is likely to remain popular forevermore.

The Sweet Pea Family, Genus and Taxonomy

While sweet pea is not a crop pea, it is closely related. Both sweet pea and peas are in the Fabaceae family, along with beans and pulses such as lentils. Sweet pea’s Latin name is Lathyrus odoratus.

Botanical Characteristics, Colors, and Fragrances

Few flowers compare to the scent of sweet pea. Its distinctive aroma has an almost candy-like quality, without coming off as overly strong or noxious. This, in addition to how readily it takes to cultivation, has made it a popular flower for florists and home gardeners for centuries.

A climbing plant by habit, sweet pea has the same tendrils that the garden pea does. With support, it can reach 6 to 8 feet. Without, it is a mound-forming plant that will creep or grow to 1-2 feet in bushy clumps.

Sweet pea comes in a huge range of colors. There is one notable exception, which we will discuss below.

History & Origins of Sweet Pea Flowers

History and Origins of Sweet Pea Flowers

Sweet pea is native to Sicily and surrounding islands in the Mediterranean. According to legend, the sweet pea was first “discovered” by a Franciscan monk wandering the hillside in the 17th century. He was so charmed by it that he brought it home and planted it in his garden.

Since then, sweet pea made its way to many gardens and nurseries, then up through Europe. In the 1800s, Scottish nursery proprietor Henry Eckford began breeding it. He developed a wide range of cultivars that are still in use today.

Sweet pea comes in a huge variety of types. These vary by hue, single or double colors, the strength of fragrance, and growing habits. Some are more heat-tolerant, while others are better for cold climates. They carry charming names such as Apricot Sprite, Fire and Ice, King’s High Scent, Prima Ballerina, Strawberry Sundae, and more.

Etymological Meaning

The sweet pea plant’s taxonomic name derives from the Greek word “Lathyros,” which directly translates to pea or pulse, and the Latin word “odoratus,” meaning fragrant. The latter is due to its strong scent when in bloom, which is one of the most powerful among flowers. Note that Lathyrus odoratus is spelled a little differently from its root Greek word.

When Are Sweet Pea Flowers in Season?

The seasonality of sweet pea flowers depends on the region. In warm climates, it can bloom in winter and spring, provided it is planted in fall. In cold regions, planters usually start it as seeds in a greenhouse. From there, they transfer it outside, where it blooms most of the summer.

Sweet peas are almost always grown as annuals. That means they go in the ground, grow, flower, and die all in a single season.


Uses and Benefits of Sweet Pea Flowers

Uses and Benefits of Sweet Pea Flowers

Although it is related to the edible garden pea, sweet pea is counterintuitively not a culinary delight. It does have other noteworthy characteristics, however.

Food and Medicine?

According to eMedicineHealth, a WebMD site, sweet peas are used in some parts of the world for food, animal fodder, and even medicine. But this isn’t common and certainly isn’t advisable. In fact, sweet pea contains known toxins to humans and animals.

Both dogs and cats should stay away from sweet peas. Humans would have to eat a lot of the seeds or stems in order to experience a reaction, but it is possible. Symptoms of poisoning include labored breathing, convulsions, and paralysis. Keep children under supervision around this pretty plant.

Fly Deterrent

Interestingly, though Lathyrus odoratus smells amazing to us, flies do not agree. If they smell it, they’ll turn tail and run, so it’s a good option for outdoor hangouts and events.

Pollinator Gardens

It’s not clear if sweet peas make good food for bees, but we know they flock to colorful patches. While we’re not quite sure what draws bees to a certain flower (or makes them avoid it), we do know they see in color and bring them in. Dramatically shaded sweet peas will accomplish that goal.


Sweet Pea Flower Meaning & Symbolism

Sweet Pea Flower Meaning and Symbolism

Sweet peas, which are the official birth flowers for April, are a symbol of blissful pleasure primarily because of their vibrant colors. In the language of flowers, many believe that these blooms leave a positive experience and a thoughtful way to say thank you as they further symbolize gratitude. 

People have developed the language of flowers over centuries – millennia, even. Red is often associated with romance, though also with courage and strength. Purple means royalty, while blue creates relaxation and pink is playful. 

Common Sweet Pea Flower Colors

Sweet pea is available in most colors of the floral rainbow. That includes:

  • Red
  • Pink
  • Lavender
  • Purple
  • White
  • Peach
  • Salmon
  • Cream
  • Periwinkle
  • Light Blue
  • Fuchsia
  • Burgundy

… and more. One color that isn’t available is yellow. The yellow sweet pea shares the fate of the blue rose. It still eludes cultivators to this day.

Some florists address the problem by dying flowers. This process involves watering neutral-colored plants, like white or ivory, with a yellow solution. They will pull it up through their stems and it will enter the bloom, coloring it.
