Sweet Pea Plants

Sweet pea plants are one of the few flowers that really capture the charm of a traditional garden. A sweet pea plant adds colour, aroma, and height to borders, trellises, and other garden supports. Its delicate petals and sweet-smelling flowers are well-known. These climbing plants are great for cottage-style gardens and can grow on canes, arches, or fences just as well.

It's even easier to raise sweet peas if you start with strong plug plants. Once they are established, sweet peas grow swiftly and bloom all summer long, giving you a constant display of beautiful blossoms. Picking them regularly makes them blossom more, so they're great for both outdoor displays and fresh-cut flowers indoors.

Frequently Asked Questions

Sweet peas do best in full sun. They need a good amount of light to grow strong stems and produce plenty of flowers. A bit of light shade is fine, but you’ll usually get better results in a brighter spot.
They’re not actually that difficult. Problems usually come from starting with weak seedlings or not giving them enough support. If you begin with strong plants and give them sun, water, and something to climb, they tend to do well.
Spring is the best time, once the risk of frost has passed. Planting at this stage gives them time to settle in before they start their main growth and flowering period.
Most sweet pea plants can reach around 1.5 to 2 metres when they have proper support. They’re great if you want to add height without taking up much space on the ground.
Yes, they need something to climb—canes, trellis, or netting all work well. Without support, they can end up tangled and won’t grow as strongly.
Yes, as long as the pot is deep enough and drains well. You’ll need to water them a bit more often in containers, and they’ll still need support as they grow.
