Explore Our Sweet Pea Seeds Varieties

Sweet peas have been bred and loved for over 300 years, and in that time gardeners and breeders have created an almost absurd number of varieties. Our collection focuses on the ones that actually perform well for home growers — varieties with outstanding fragrance, strong color, and manageable growth habits. Because what's the point of a sweet pea that looks great but doesn't smell like anything? That's just a regular flower at that point. The scent is the whole deal.

The Old Spice Mix is where nostalgia meets the garden. This is a blend of heirloom varieties that traces back to the original sweet peas bred in the 1800s and early 1900s — the kinds your great-grandmother would've grown along a picket fence. The flowers are smaller and simpler than modern types, but the fragrance is absolutely devastating in the best possible way. Deep, complex, and strong enough to perfume an entire cutting garden. Colors range from soft lavender and pale pink to deep maroon and bicolor combos. If scent is your top priority — and honestly, it should be with sweet peas — Old Spice is the gold standard.

Royal Family Mix is the variety for gardeners who want big, ruffled blooms on long, strong stems. This is a Spencer-type sweet pea, which means the petals have that signature wavy, almost crinkled quality that looks incredible in arrangements. The color range is broad — pinks, purples, blues, whites, crimsons, and salmons — and the stems are long enough for serious cut flower work. These climb vigorously, usually reaching 5 to 6 feet, and they bloom prolifically if you keep picking. Which you should. We'll get to that.

Painted Lady is one of the oldest sweet pea varieties still in cultivation — we're talking 1730s old. The blooms are bicolor, with a rosy pink upper petal and a creamy white lower petal, and the fragrance is classic old-world sweet pea perfume. There's something genuinely special about growing a flower that's been passed down through nearly 300 years of gardens. It connects you to a lineage of growers stretching back centuries. And it smells absolutely phenomenal.

Matucana is another heritage variety that's close to the original wild species from Sicily. Deep bicolor blooms — rich purple upper petals with a vivid magenta lower petal — and pound for pound, probably the most intensely fragrant sweet pea you can grow. The flowers are smaller than Spencer types but the scent is nuclear. One stem in a bud vase will perfume a whole kitchen. If you're the kind of grower who prioritizes smell over size, Matucana is your variety and I'm not sure it's even close.

For folks working with limited space, Bijou Mix is a dwarf bush-type sweet pea that tops out at about 18 inches and doesn't need a trellis or support structure. It just bushes out and blooms. The flowers are smaller but still fragrant, and the color mix includes pinks, blues, purples, and whites. Perfect for containers, window boxes, or the front edge of a flower border where you want color and scent without the height. Not everybody has room for a six-foot climbing vine, and Bijou respects that.

Cupani is another granddaddy of the sweet pea world — named after the Sicilian monk who first sent sweet pea seeds to England in 1699. The blooms are bicolor purple and maroon, and the scent is as strong as anything you'll find in the genus. It's a vigorous climber that'll hit 6 to 8 feet easily. Growing Cupani feels like growing a piece of botanical history, and honestly, the fact that people have been obsessed with this exact flower for over 300 years tells you everything you need to know about how good it is.

One important note that trips some people up: sweet peas are ornamental flowers. They are not edible. The seeds and pods contain compounds that should not be consumed. Don't confuse these with sugar snap peas or garden peas — totally different plants. Sweet peas are for looking at, smelling, and cutting for vases. And they are spectacularly good at all three of those things.

Gardening Insights: Growing Sweet Peas from Seed at Home

Here's the thing about sweet peas that catches some people off guard — they're a cool-season flower. While most of the garden is just waking up in early spring, sweet peas are already out there doing their thing. They actually prefer temperatures between 55°F and 65°F, which means they bloom best in the cool shoulder seasons of spring and early summer. Once the heat of midsummer kicks in — consistently above 80°F — most sweet peas start declining. So timing is everything with these, and getting them started early is the key to a long, productive bloom season.

In most of the US, that means sowing seeds in late winter to very early spring — even while there's still a chance of light frost. Sweet peas are surprisingly cold-hardy as seedlings. They can handle temperatures down into the upper 20s once established. In zones 7 and warmer, a lot of gardeners actually plant sweet pea seeds in fall for even earlier spring blooms — the plants overwinter as small seedlings and explode into growth when spring arrives. If you're in zones 3–6, late February through March is the typical indoor start window, with transplanting outdoors as soon as the soil can be worked — usually 4 to 6 weeks before your last frost date.

Sweet pea seeds have a hard outer coat, so soaking them in room-temperature water for 12 to 24 hours before planting helps speed up germination. Some gardeners also nick the seed coat gently with a small file or nail clippers — just enough to break through the outer shell without damaging the inside. Either method works. Or you can skip it entirely and just accept that germination might take a little longer. They'll still come up, it just might take 14 to 21 days instead of 7 to 10.

Plant seeds about an inch deep in rich, well-draining soil. Sweet peas like fertile ground with plenty of organic matter — compost is your best friend here. They prefer a slightly alkaline to neutral pH, roughly 7.0 to 7.5, which is a little unusual since a lot of garden plants lean acidic. If your soil is on the acidic side, a light dusting of garden lime worked into the bed before planting can help nudge the pH in the right direction. Not strictly necessary, but it gives them a boost.

Sunlight is important but nuanced. Sweet peas want full sun — at least 6 hours of direct light — but in warmer climates, afternoon shade actually helps extend the bloom season by keeping root zones cooler. A spot that gets morning sun and light afternoon protection is ideal in zones 7 and above. In cooler northern zones, full sun all day is fine and preferred.

Climbing varieties need something to grab onto. A trellis, a section of fence, some netting stretched between stakes, or even a teepee of bamboo poles — sweet peas climb using tendrils that coil around whatever they can reach. Give them a support structure right from the start so the tendrils have something to latch onto as the plant grows. They'll climb 5 to 8 feet depending on variety, so make sure your support is tall enough. There's nothing sadder than a sweet pea vine that runs out of trellis and starts flopping over the top with nowhere to go.

And here's the single most important harvest tip I can give you: pick them constantly. Like, aggressively. Every time a flower opens and you don't cut it, the plant gets closer to setting seed. And once sweet peas start putting energy into seed production, they slow down — and eventually stop — making new flowers. By cutting every bloom you see — even if it's just to stick in a glass of water by the sink — you're telling the plant "nope, keep trying, make more flowers." The more you pick, the more they bloom. It's a beautiful cycle, and it means your house is constantly filled with the best-smelling flowers on the planet. Not a bad trade-off.

Mulch around the base of the plants to keep roots cool and retain moisture. Consistent watering is important — sweet peas like even moisture but not soggy feet. Water at the base, not overhead, to reduce mildew risk. And enjoy every single day of the bloom season, because sweet peas are one of those fleeting pleasures that makes spring feel like a gift.
