When to Grow

High Scent is the long game among sweet peas: 80–110 days from sowing to those cream-and-lavender blooms, so sow early and give it the full stretch of cool weather it wants. It suits a spring or a fall planting. Soak the seeds in warm water for 24 hours, then direct sow — the preferred method — 3–4 weeks before your last frost, setting seed ¼ to ½ in. deep and about 6 in. apart. If you want a head start, sow indoors 4–6 weeks ahead and transplant out. Germination takes 14–21 days and is best at 55–65°F.

How to Sow and Plant

  • Soak seeds in warm water for 24 hours before planting.
  • Direct sow 3-4 weeks before last frost (preferred) or start indoors 4-6 weeks before transplanting out.
  • Plant seeds 1/4 to 1/2 inch deep.
  • Ideal germination temperature is 55-65 F.
  • Seeds germinate in 14-21 days.

How to Grow

  • Provide rich, well-drained soil and adequate moisture.
  • Pinch main growing stem when plants are 6 inches tall to encourage better branching.
  • Provide trellising.
  • Keep deadheaded to encourage continued blooming.

PESTS/SPECIAL CONSIDERATIONS

  • Aphids are a pest of sweet pea and will transmit virus.
  • Prevent aphids by encouraging beneficials such as ladybugs.
  • Powdery mildew can be a problem as well; be sure to space plants adequately to promote good air flow.

How to Save Seeds

  • A very easy seed-saving crop!
  • Simply allow the pods, which resemble small pea pods, to turn brown and dry on plants.
  • Harvest seeds and store in a cool, dry, dark place.

FAQ

What do High Scent flowers look and smell like?

They are celebrated for an intense floral scent, with mesmerizing ruffled petals in soft cream hues kissed with delicate lavender fringes. The mauve-tinged blooms perfume the air with honey-like aromas, making this a choice variety for cut flowers. It was developed in Auckland, New Zealand, by botanist and ornamental specialist Dr Keith Hammett.

What support and spacing do High Scent vines need?

Provide trellising, and pinch the main growing stem when plants are 6 inches tall to encourage better branching. Space plants about 6 in. apart, and keep them deadheaded to encourage continued blooming. Powdery mildew can be a problem, so space plants adequately to promote good air flow. Aphids are a pest of sweet pea and will transmit virus, so encourage beneficials such as ladybugs.

Can I save my own High Scent seed, and is the plant safe to handle?

Sweet peas are an easy seed-saving crop: let the small, pea-like pods turn brown and dry on the plant, then harvest the seed and store it somewhere cool, dark and dry. Note that all parts of the plant — seeds, pods and foliage alike — are poisonous, so High Scent is grown for ornament and cut flowers only, never for eating.
