Sweet peas (Lathyrus odoratus) are one of the most beautiful and fragrant flowers to grow in a garden. Starting sweet peas from seed indoors gives you a head start on the growing season, resulting in stronger plants and earlier flowers.

Whether you’re growing annual sweet peas for fragrance or perennial sweet peas for long-term blooms, starting them indoors in winter or early spring is the best way to ensure healthy, robust plants.

In this guide, you’ll learn:

✔️ The best time to start sweet pea seeds indoors
✔️ How to plant and care for sweet pea seedlings
✔️ The importance of root trainers and pre-soaking seeds
✔️ How to transplant sweet peas outdoors successfully

Let’s get started on growing sweet peas from seed indoors like a pro! 🌿🌸

1. When to Start Sweet Peas Indoors?

The best time to sow sweet peas indoors depends on how early you want flowers.

Recommended Sowing Times:

✔️ Autumn Sowing (October–November) – Produces stronger, earlier-flowering plants in spring.
✔️ Winter Sowing (January–February) – Ideal for an early start before spring planting.
✔️ Early Spring Sowing (March–April) – Best for direct planting in spring gardens.

Tip: The earlier you sow sweet peas indoors, the bigger and stronger the plants will be when moved outside.

2. How to Grow Sweet Peas from Seed Indoors (Step-by-Step Guide)

Step 1: Gather Your Materials

✔️ Sweet pea seeds (Choose fragrant varieties like ‘Cupani’ or ‘Spencer Mix’)
✔️ Root trainers or deep pots (For strong root development)
✔️ Seed compost (Light, well-draining soil)
✔️ Watering can with a fine rose (For gentle watering)
✔️ Grow lights or a sunny windowsill

Tip: Sweet peas have long roots, so deep containers like root trainers or toilet rolls work best.

Step 2: Pre-Soak Seeds for Faster Germination

Sweet pea seeds have a hard outer shell, which can slow down germination.

✔️ Soak seeds in warm water overnight (12–24 hours).
✔️ This softens the seed coat, helping them sprout faster.
✔️ If seeds don’t swell, gently nick the outer shell with a nail file.

Tip: Some gardeners don’t soak their seeds, but it can speed up germination by a few days.

Step 3: Sowing Sweet Pea Seeds Indoors

✔️ Fill root trainers or deep pots with seed compost.
✔️ Sow one seed per pot, pushing it 2–3 cm (1 inch) deep.
✔️ Cover lightly with compost and firm down gently.
✔️ Water lightly but evenly to avoid overwatering.

Tip: Avoid planting too shallow—deep roots help support strong growth.

Step 4: Provide the Right Growing Conditions

🌱 Temperature: Keep seeds at 15–18°C (59–64°F) for best germination.
💡 Light: Place on a bright windowsill or under grow lights.
💧 Watering: Keep compost moist but not soggy.

Germination Time: 🌱 7–14 days (depending on variety and conditions).

Tip: Once seedlings appear, move them to a cooler place (10–12°C/50–54°F) to prevent leggy growth.

3. How to Care for Sweet Pea Seedlings Indoors

1. Pinching Out for Bushier Growth

✔️ Once seedlings reach 10 cm (4 inches) tall, pinch out the growing tip just above a pair of leaves.
✔️ This encourages stronger, bushier plants with more side shoots and flowers.

Tip: Don’t pinch out perennial sweet peas—they don’t respond well to it.

2. Watering & Feeding

✔️ Water only when the compost feels dry—too much water causes weak growth.
✔️ No fertilizer needed until seedlings are planted outside.

3. Providing Support

✔️ As seedlings grow, use small sticks or canes to train them.
✔️ This prevents them from tangling and encourages strong stems.

Tip: Sweet peas are natural climbers, so they attach to supports easily once planted out.

4. Transplanting Sweet Peas Outdoors

After 6–8 weeks, sweet peas will be ready for planting outdoors.

When to Plant Sweet Peas Outside

✔️ March–May – After the risk of frost has passed.
✔️ Harden off for 7–10 days before transplanting.

How to Harden Off Sweet Peas Before Planting

✔️ Move seedlings outside during the day for increasing amounts of time.
✔️ Keep them sheltered from wind and rain at first.
✔️ After 7–10 days, they’ll be ready for full outdoor conditions.

Tip: If a late frost is expected, cover young plants with horticultural fleece at night.

5. How to Plant Sweet Peas in the Garden

Once hardened off, follow these steps for successful transplanting.

✔️ Choose a sunny, sheltered spot—Sweet peas love full sun.
✔️ Improve soil with compost or well-rotted manure before planting.
✔️ Space plants 20–30 cm (8–12 inches) apart.
✔️ Water well after planting to help roots establish.

Providing Support for Sweet Peas

✔️ Use canes, trellises, or netting for climbing varieties.
✔️ Tie stems loosely to supports with twine as they grow.

Tip: Pinch off flowers regularly to encourage continuous blooming throughout the summer!

6. Common Problems & Solutions

Tip: Sweet peas are frost-hardy, but young plants still need protection from extreme cold.

7. Final Thoughts: Growing Sweet Peas from Seed Indoors

✔️ Start sweet peas indoors in autumn, winter, or early spring for stronger plants.
✔️ Use deep root trainers or pots to encourage healthy root growth.
✔️ Pre-soak seeds before sowing to speed up germination.
✔️ Pinch out young plants for bushier growth and more flowers.
✔️ Harden off seedlings before transplanting outdoors in March–May.

Are Sweet Peas Perennials? Understanding the Life Cycle of Sweet Peas

Sweet peas (Lathyrus odoratus) are a garden favorite, admired for their fragrance, delicate petals, and colorful blooms. Many gardeners wonder: Are sweet peas perennials, or do they need to be replanted every year?

The answer depends on the variety. While most sweet peas are annuals, there are perennial sweet pea varieties that return year after year.

In this guide, you’ll learn:

✔️ The difference between annual and perennial sweet peas
✔️ How to grow and care for both types
✔️ Pros and cons of perennial sweet peas
✔️ Best varieties for UK gardens

Let’s explore whether sweet peas are perennials or annuals! 🌿🌸

1. Are Sweet Peas Perennials or Annuals?

There are two types of sweet peas:

1. Annual Sweet Peas (Lathyrus odoratus) 🌸

✔️ Most common type—needs replanting each year.
✔️ Grows fast from seed, blooms all summer, then dies after flowering.
✔️ Produces strong fragrance and larger flowers.
✔️ Popular varieties: ‘Cupani’, ‘Spencer Mix’, ‘Old-Fashioned Mix’.

2. Perennial Sweet Peas (Lathyrus latifolius) 🌿

✔️ Comes back every year—long-lived, hardy plant.
✔️ Produces smaller, less fragrant flowers but vigorous growth.
✔️ Can become invasive if not managed properly.
✔️ Popular varieties: ‘Everlasting Pea’, ‘Red Pearl’, ‘White Pearl’.

Key Difference: Annual sweet peas have a stronger scent and larger blooms, while perennial sweet peas are hardier but have smaller, less fragrant flowers.

2. What Are Perennial Sweet Peas?

Perennial sweet peas (Lathyrus latifolius) are also called Everlasting Peas.

Characteristics of Perennial Sweet Peas

🌿 Long-lived – Grows back every spring from the same root system.
🌸 Climbing habit – Can grow up to 2m (6ft) tall.
☀️ Hardy & low-maintenance – Tolerates frost and drought.
⚠️ Less fragrance – Unlike annual sweet peas, they lack strong scent.
💜 Flowers in pink, purple, and white – Attractive but not as showy as annual varieties.

Tip: Perennial sweet peas are great for wild gardens, fences, and trellises but require management to prevent spreading.

3. How to Grow Perennial Sweet Peas

Best Time to Plant

✔️ Spring (March–May) – Ideal for sowing directly outdoors.
✔️ Autumn (September–October) – Can be started in a greenhouse for early growth next year.

Planting Guide

✔️ Choose a sunny or partially shaded spot.
✔️ Ensure well-draining soil—they tolerate poor soil conditions.
✔️ Sow seeds 2–3 cm deep in prepared beds or containers.
✔️ Water lightly until established, then reduce watering.

Training & Support

✔️ Use trellises, fences, or garden obelisks for climbing support.
✔️ Tie stems loosely as they grow.

Pruning & Maintenance

✔️ Cut back dead stems in autumn for tidier growth.
✔️ Remove seed pods to prevent self-seeding (they can spread aggressively).

Tip: If left unchecked, perennial sweet peas can become invasive, so prune regularly.

4. How to Grow Annual Sweet Peas for a Single Season

🌿 Sow seeds indoors (Jan–March) or directly outdoors (April–May).
🌸 Provide full sun and rich, well-draining soil.
🌿 Pinch out growing tips when 10 cm tall for bushier growth.
🌸 Deadhead flowers regularly to extend blooming season.
🌿 Support with canes, trellises, or netting for climbing.

Tip: Annual sweet peas bloom longer and have stronger fragrance than perennials.

5. Pros & Cons of Perennial Sweet Peas

Tip: If you love fragrance and showy flowers, stick to annual sweet peas. If you want low-maintenance climbers, choose perennial sweet peas.

6. Best Sweet Pea Varieties to Grow

Are Sweet Peas Edible? Understanding the Difference Between Sweet Peas and Edible Peas

Sweet peas (Lathyrus odoratus) are beautiful climbing flowers, well-loved for their fragrance and vibrant colors. However, many gardeners wonder: Are sweet peas edible?

The short answer is no—sweet pea plants are not safe to eat. Unlike edible peas (Pisum sativum), sweet peas contain toxic compounds that can be harmful if ingested.

In this guide, you’ll learn:

✔️ Why sweet peas are not edible
✔️ The difference between sweet peas and edible peas
✔️ Potential health risks of consuming sweet peas
✔️ Best edible alternatives for your garden

Let’s dive in and understand why sweet peas are for decoration, not dinner! 🌿🌸

1. Are Sweet Peas Edible?

No, sweet peas are toxic and should not be eaten. All parts of the sweet pea plant, including the seeds, pods, flowers, and leaves, contain compounds that can be harmful to humans and animals.

Important: Even though sweet peas produce pods that look like edible peas, they must not be eaten.

2. Difference Between Sweet Peas and Edible Peas

Sweet peas (Lathyrus odoratus) are often confused with edible garden peas (Pisum sativum). While they belong to the same plant family (Fabaceae), they are completely different species.

Comparison Table: Sweet Peas vs. Edible Peas

Tip: If you want both beauty and edibility, grow edible peas like sugar snap peas or snow peas instead of sweet peas.

3. Why Are Sweet Peas Toxic?

Sweet peas contain toxic compounds, primarily:

🔹 Lathyrogens – Amino acids that can cause neurological disorders in high doses.
🔹 Beta-aminopropionitrile (BAPN) – Can lead to muscle weakness and joint pain.

Eating sweet pea seeds or pods over time can result in lathyrism, a condition that affects the nervous system and can cause paralysis in severe cases.

Note: Poisoning from sweet peas is rare but can occur if large amounts are consumed.

4. Are Sweet Peas Toxic to Pets?

Yes, sweet peas are toxic to dogs, cats, and other pets.

Symptoms of Sweet Pea Poisoning in Pets:

⚠️ Vomiting & diarrhea
⚠️ Lethargy & weakness
⚠️ Seizures (in severe cases)

Tip: If your pet eats sweet peas, contact a veterinarian immediately.

5. Safe Alternatives: Edible Peas to Grow Instead

If you’re looking for edible plants that resemble sweet peas, try these:

1. Sugar Snap Peas (Pisum sativum var. macrocarpon)

✔️ Edible pods & peas
✔️ Crisp, sweet flavor
✔️ Climbing variety (needs support)

2. Snow Peas (Pisum sativum var. saccharatum)

✔️ Flat, tender pods
✔️ Great for stir-fries & salads
✔️ Fast-growing & easy to cultivate

3. Garden Peas (Shelling Peas) (Pisum sativum)

✔️ Classic edible pea variety
✔️ Sweet, plump peas inside non-edible pods
✔️ Thrives in cool climates

Tip: Edible pea flowers are usually small and white, unlike the brightly colored blooms of sweet peas.

6. Final Thoughts: Are Sweet Peas Safe to Eat?

✔️ Sweet peas are NOT edible – all parts of the plant are toxic.
✔️ Avoid consuming the pods & seeds, as they contain harmful amino acids.
✔️ Pets & livestock should not eat sweet peas – they can cause digestive and neurological issues.
✔️ Grow edible pea varieties instead, like sugar snap peas or snow peas.
