When to sow Antirrhinum Seeds 

Antirrhinum seeds are best sown indoors from January to April for flowering displays throughout summer and into autumn. Seeds can be started in trays or pots under cover and grown on before planting outdoors once the risk of frost has passed. Earlier sowings often result in a longer flowering season. 

How to grow Antirrhinums from seed 

Antirrhinums are easy to grow from seed and are prized for their colourful flower spikes and long flowering period. Sow seeds thinly on the surface of moist seed compost and do not cover them, as they need light to germinate. Place containers in a warm, bright location and keep the compost moist but not waterlogged. Once seedlings are large enough to handle, transplant them into individual pots and gradually acclimatise them before planting outdoors. Grow antirrhinums in fertile, well-drained soil in a sunny position for the best display. 

How long does it take for Antirrhinums to flower? 

Antirrhinums typically begin flowering from early to mid-summer and can continue blooming well into autumn, depending on the sowing date and growing conditions. Regular deadheading encourages plants to produce more flowers and helps extend the flowering season. 

Why grow Antirrhinums from seed? 

Growing antirrhinums from seed is a cost-effective way to raise a large number of plants and enjoy a much wider choice of colours, flower shapes and plant heights. They are ideal for borders, containers and cutting gardens, producing long-lasting blooms that add colour and structure to summer displays. Their nectar-rich flowers can also attract pollinating insects to the garden. 

Where can you grow Antirrhinums? 

Antirrhinums thrive in borders, cottage gardens, raised beds and containers. They grow best in a sunny, sheltered position with fertile, well-drained soil. Dwarf varieties are well suited to pots and edging displays, while taller varieties make excellent background plants and cut flowers. With their versatility and long flowering season, antirrhinums are suitable for gardens of all sizes. 

Which Antirrhinum variety should I choose? 

The best antirrhinum variety depends on the type of display you would like to create. Dwarf varieties are perfect for containers, window boxes and bedding schemes, while taller varieties provide height and make excellent cut flowers. Available in a wide range of colours, from soft pastels to vibrant reds, oranges and pinks, antirrhinums can complement almost any garden style.
