7 flower seeds to sow in February for a colourful garden all season

February marks an important transition in the gardening calendar. While winter may still linger in many regions, this month is ideal for starting several flower seeds indoors or under protection so they can bloom beautifully in spring and summer. Early sowing allows plants enough time to develop strong roots and healthy foliage before being transplanted outdoors.


Choosing the right varieties for February sowing can ensure continuous colour, attract pollinators, and create a vibrant landscape that lasts through multiple seasons. Many hardy and half-hardy annuals respond well to early planting, making this the perfect moment to prepare for a flourishing garden ahead.

Marigolds are classic garden flowers that thrive in full sunlight and are simple to grow from seed in February. Besides adding cheerful golden and orange tones, they are valued in vegetable gardens for helping deter certain pests.

Geraniums are popular summer favourites known for clusters of colourful, long-lasting flowers and pleasant fragrance. They can be started indoors in February with warmth and proper care, giving them a head start before outdoor planting. Many gardeners also overwinter geraniums and prune them at this time to encourage fresh growth, ensuring abundant blooms that brighten containers, balconies, and borders.

Rudbeckias produce bold yellow petals with dark centres, creating a striking, classic garden appearance. These native flowers attract pollinators and help support a lively garden ecosystem. Seeds can be started indoors weeks before the last frost or sown directly in warmer regions toward late February.

Cornflowers are charming annuals often recognised for their sky-blue blooms, though they also appear in pink, purple, red, and white. They reseed easily, attract pollinators and birds, and suit cottage-style or wildflower gardens. February sowing indoors helps seedlings establish early, leading to abundant flowering later in the season and continuous natural colour in garden spaces.

Petunias are popular flowering annuals known for their wide range of vibrant colours and long blooming season. Because they grow slowly from seed, gardeners often start petunia seeds indoors in late winter or February, allowing enough time for strong seedlings to develop before transplanting outdoors after the last frost. Once established, petunias flower continuously through spring and summer, making them ideal for borders, hanging baskets, and containers that need lasting seasonal colour.

Larkspur produces tall, elegant flower spikes ideal for decorative displays and floral arrangements. These hardy annuals often require a period of cold to germinate, making late winter or February sowing particularly suitable. Starting them early helps plants mature in time for striking blooms, adding vertical structure and soft colour tones that enhance the garden’s seasonal variety.

One of the favourite flowers for its distinctive "dragon" blooms and variety of colours is the snapdragon. Since it is a slow-growing plant, planting seeds indoors in February will provide robust seedlings for transplanting when the weather warms up. With its long blooming season and uses for borders or containers, it is an important plant for keeping colour and interest throughout most of the gardening year.

Planting flower seeds in February is a simple but effective way to begin building a colourful garden throughout the year. By selecting hardy and early-blooming varieties such as marigolds, petunias and snapdragons, gardeners can provide a constant source of blooms, support beneficial pollinators, and add colour and texture to outdoor spaces with a variety of hues and textures. Careful planning in this transitional phase will pay off in the end with a lush garden that honours the beauty of spring and summer.
