Sweet Pea Flower Seeds Packet

FREE SHIPPING on seeds when you order 5 packs or more

Sweet pea seeds grow into a climbing annual grown almost entirely for a fragrance that no modern breeding has managed to improve on. Shido sweet pea seeds are non-GMO and hermetically vacuum-sealed — a fragrant start for a vine most modern gardens have forgotten — while standard paper-packed seeds lose germination viability within approximately one year.

It is grown almost entirely for a fragrance that no amount of modern breeding has managed to improve on, generation after generation. Start it in cool weather and give it a support to grip early, and it repays both with armfuls of cut flowers for weeks. No modern hybrid has ever managed to improve on a scent this old and this exact. Cut it constantly rather than sparingly, since regular cutting is what keeps a sweet pea vine producing new flowers. Every packet ships germination-tested at independent third-party labs before packaging.

How to Plant Sweet Pea from Seed

PlantCare

When to Plant Seeds

  • Cool Climates: Sow seeds in early spring, as soon as the soil is workable.
  • Warm Climates: Plant in late fall or winter to allow for early spring blooms.

Preparing the Planting Site

  • Soak seeds in warm water for 24 hours before planting to soften the seed coat.
  • Alternatively, scarify (nick) the seed coat with sandpaper to enhance germination.
PlantCare water

Pre-Treating Seeds for Faster Germination

  • Soak seeds in warm water for 24 hours before planting to soften the seed coat.
  • Alternatively, scarify (nick) the seed coat with sandpaper to enhance germination.

Starting Seeds

Outdoors: Plant seeds 1 inch deep and 2-3 inches apart. Water gently to moisten the soil. Germination occurs in 7-14 days, depending on temperature. Once seedlings reach 4-6 inches tall, thin them to 6 inches apart.

Indoors: If starting indoors, plant seeds in biodegradable pots 4-6 weeks before the last frost. Keep in a cool, well-lit location. Transplant carefully to avoid disturbing the roots.

Pro Tip

Provide a trellis or support for climbing, and pinch back growing tips to encourage bushier growth.

Bonus: Sweet peas are great cut flowers with a lovely fragrance, so don’t forget to harvest regularly to keep the blooms coming!

The Story Behind This Packet

Sweet Pea seeds have been part of the Shido lineup since the collection first opened, grown into a climbing annual grown almost entirely for a fragrance that no modern breeding has managed to improve on. Every packet is illustrated in the style of early-1900s Japanese woodblock printing, drawn in-house rather than licensed, which means the artwork on this packet exists nowhere else. The seeds themselves are hermetically vacuum-sealed, a packaging choice that has as much to do with the garden as the growing does: a standard paper packet starts losing viability within about a year, while a vacuum seal holds that line for years longer, so the packet in a drawer is still a packet worth planting whenever the moment actually arrives. Shido treats the seed itself as worth that extra step, on the theory that a gardener who buys sweet pea seeds deserves a packet that is still viable whenever they finally get around to using it, not just the season they bought it.

What it's used for

1. Ornamental Landscaping:

  • Perfect for trellises, garden fences, pergolas, and arches.
  • Adds a romantic and cottage-style charm to gardens.

2. Cut Flowers:

  • Sweet peas are widely used in floral arrangements and bouquets due to their delicate texture and pleasant fragrance.
  • Long stems and vibrant colours make them ideal for decorative purposes.

3. Pollinator Gardens:

  • Since sweet peas attract butterflies and bees, they contribute to a healthy ecosystem in gardens.

4. Companion Planting:

  • Sweet peas improve soil health by fixing nitrogen, making them a good companion for vegetables like beans and tomatoes.
Growth Requirements

Light:

  • Requires full sun (6-8 hours per day) for optimal flowering.
  • In hot climates, partial afternoon shade can help extend the blooming season.

Soil:

  • Prefers well-drained, fertile soil with a pH of 6.0-7.5.
  • Adding organic compost or aged manure before planting improves soil quality.

Watering:

  • Keep soil consistently moist but not soggy.
  • Water at the base to prevent fungal diseases.

Temperature & Climate:

  • Thrives in cooler temperatures (50-70°F / 10-21°C).
  • In warmer regions, plant sweet peas in late fall or early winter for spring blooms.

Fertilization:

  • Use a low-nitrogen, high-phosphorus fertilizer to encourage blooms.
  • Avoid excessive nitrogen, which promotes foliage growth but reduces flowering.
Maintenance

Watering:

  • Water deeply once or twice a week, especially during dry spells.
  • Avoid wetting foliage to prevent fungal issues.

Deadheading & Pruning:

  • Remove spent flowers (deadhead) to encourage continuous blooming.
  • Trim back leggy vines to promote bushy growth.

Mulching:

  • Apply a thin layer of mulch around plants to retain moisture and suppress weeds.

Fertilization:

  • Use a liquid bloom booster fertilizer every 2-3 weeks during the flowering period.
Pests and Diseases

Pests:

  • Aphids – Treat with insecticidal soap or neem oil.
  • Slugs and snails – Hand-pick or use natural deterrents like crushed eggshells.
  • Spider mites – Increase humidity and spray plants with water.

Diseases:

  • Powdery mildew – Ensure proper air circulation and avoid overhead watering.
  • Root rot – Prevent by planting in well-drained soil and avoiding overwatering.
  • Fusarium wilt – Remove infected plants and rotate crops yearly.
