What Seeds to Sow in October in Temperate European Climates
October is a quieter but still useful sowing month in temperate European gardens. Hardy annual flowers can still be sown for earlier blooms next year, while sweet peas, snapdragons, pansies and other cool-season flowers can be started in trays or pots under cover. In the vegetable garden, concentrate on winter salads and cold-tolerant leafy crops such as mesclun, spinach, rocket, lettuce and pak choi.

Hardy Flowers to Sow Outdoors in October
October is one of the final opportunities to direct-sow hardy annual flowers before winter. Autumn-sown plants can establish before the coldest weather arrives and often flower earlier the following spring and summer. Outdoor sowing is most reliable in mild or sheltered gardens; colder and exposed locations may need additional protection.
Calendula
Calendula is one of the easiest and most dependable flowers for autumn sowing. Choose Fiesta Gitana Mix, Ivory Princess or Funky Stuff.
Browse calendula seeds →Cornflowers
Cornflowers tolerate cool conditions well and autumn sowing can produce established plants that flower earlier the following year. Choose Cornflower Blue Boy, Black Ball or Cornflower Mix.
Browse cornflower seeds →Nigella
Nigella, also known as love-in-a-mist, is a hardy annual well suited to cool-season sowing. Direct sow where you want the plants to flower. Choose Miss Jekyll Skyblue or Miss Jekyll Rose.
Browse nigella seeds →Annual Poppies
Poppies are excellent candidates for autumn sowing. Sow directly into prepared soil because their roots dislike disturbance once established. Recommended varieties include Amazing Grey, Lauren's Grape, Dawn Chorus, Purple Peony and Black Peony.

Linum Grandiflorum Mix is a hardy annual suited to informal borders and naturalistic planting. Autumn sowing can produce an earlier display the following year.
Browse linum seeds →October Flower Sowing Tip
Choose a sunny position with free-draining soil and avoid sowing into cold, waterlogged ground. In colder or exposed gardens, sowing into pots or modules can be safer so young plants can be protected during severe winter weather.
Flowers to Start in Trays & Pots in October
Several flowers benefit from an autumn start but are more reliable when their seedlings receive some winter protection. Sow in trays, modules or pots and overwinter in a bright cold frame, unheated greenhouse or another sheltered position.
Sweet Peas
Sweet peas are one of the best flowers to start in October. Autumn sowing allows plants to develop strong root systems through winter and can lead to earlier flowers the following year. Sow in deep pots and overwinter somewhere cool and protected. Choose Cupid Pink or King Size Coronation Mix .
Browse sweet pea seeds →Snapdragons
Snapdragons can be started in trays during autumn for earlier plants the following year. Keep seedlings bright, cool and protected from severe frost. Choose Twinny Peach, Grandiflorum Mix or Snapshot Coral Bicolor.
Browse snapdragon seeds →Cerinthe Pride of Gibraltar
Cerinthe Pride of Gibraltar can be started in autumn for strong plants and earlier flowers the following season. In colder areas, young plants are best overwintered under protection.
Browse cerinthe seeds →California Poppies
California poppies can be autumn-sown in mild, sunny and free-draining gardens. In colder parts of temperate Europe, October sowings are safer with some protection. Choose Appleblossom Chiffon, Thai Silk Pink Champagne, Thai Silk Formula Mix, Thai Silk Rose Chiffon, Apricot Chiffon or XL Jelly Beans.

Autumn seedlings generally need plenty of light but very little warmth. Avoid keeping them in a heated room where soft, weak growth can develop. A cold frame or unheated greenhouse is ideal for many autumn-sown flowers.
Flowers for Winter & Spring Colour
October is also useful for starting cool-season flowers that can provide colour through the colder months in mild regions or develop into strong plants for spring. Sow under cover where winters are cold.
Pansies
Pansies thrive in cool conditions and can be started for winter and spring displays. Keep young plants bright and cool, with protection from severe frost. Choose Frizzle Sizzle Raspberry, Back to Black, Swiss Giants Mix, Inspire Plus Marina or Inspire Plus White.

In mild climates, autumn-sown calendula can establish through the cooler months and provide particularly early flowers. Fiesta Gitana Mix is an excellent compact choice for beds and containers.
Browse calendula seeds →Sweet Peas for Early Spring Growth
October-sown sweet peas spend winter building a strong root system rather than producing lots of top growth. When temperatures and light levels rise in spring, established plants can grow quickly and flower earlier.
Browse sweet pea seeds →Wildflower Mixes for October Sowing
Early October can still be a useful time to establish suitable wildflower mixtures, especially in milder areas. Sow into prepared, weed-free soil so seedlings have the best chance to establish before winter.

October vegetable sowing should concentrate on winter salads, hardy leafy vegetables and fast-growing crops. Growth slows considerably as daylight decreases, so protection from a cloche, cold frame or unheated greenhouse becomes increasingly useful.
Organic Mesclun Asian Mix
Mesclun Asian Mix is particularly useful for cool-season growing. Sow for tender young leaves and harvest as a baby-leaf crop. In colder regions, grow under a cloche, cold frame or unheated greenhouse.

Welsh Onion Ishikura is cold tolerant and can be autumn-sown for future harvests. In colder regions, protect young seedlings through winter.
View Welsh onion seeds →October Vegetable Tip
Think of October sowing primarily as establishing crops rather than producing rapid harvests. As the days shorten, growth slows considerably. Some crops may produce a few young leaves before winter and then remain almost dormant until increasing light levels encourage fresh growth in late winter or spring.
Herbs to Sow in October
Herb sowing becomes limited in October, but coriander and parsley can still be useful choices when grown with protection.
Coriander prefers cooler weather and is less prone to bolting than during hot summer conditions. Sow in pots or greenhouse beds for young leaves.
Parsley can still be started under cover in October. Germination becomes slower as temperatures fall, so maintain even moisture and keep seedlings bright and protected.
Easy to Grow & Small-Space Friendly
October sowing is still possible in pots, balcony planters and raised beds. Containers are particularly useful at this time of year because they are easier to protect from severe weather.
Best Flowers for Pots & Balconies
Fiesta Gitana calendula, pansies, sweet pea Cupid Pink, Snapdragon Twinny Peach and California poppies in mild areas.
Best Winter Salads for Containers
Mesclun Asian Mix, Mesclun Salad Leaves, Spinach Renegade, Rocket Esmee, Lettuce Salad Bowl and Pak Choi Taisai.
Easiest October Flowers for Beginners
Calendula, cornflowers, nigella and annual poppies are straightforward autumn-sowing choices.
October Gardening Tips
October sowing is increasingly about establishing hardy plants before winter, protecting young seedlings and taking advantage of cool conditions for winter salads.
Calendula, cornflowers, nigella, linum and annual poppies can still be autumn-sown for earlier flowers next year.
Sweet peas, snapdragons and pansies can be started now and overwintered in bright, cool, protected conditions.
Mesclun, spinach, rocket, lettuce and pak choi are among the most useful crops for October sowing.
Cold, saturated soil can cause more problems than low temperatures. Use free-draining beds, pots and seed compost.
Mild areas have a longer outdoor sowing season. Northern, continental, high-altitude and exposed gardens should move more sowings under protection.
