How to Sow Mixed Aubreita Seeds in the UK 

Mixed Aubreita is a perfect perennial, native to Central Asia and Southern Europe. Named after a French painter, Aubreita is renowned for its stunning 4-inch purple flowers with vibrant yellow centres. This hardy plant is a popular choice for rockeries, containers, window boxes, path edging, and walls. As a spreading plant, Aubreita can cover over 20 inches from its original location, making it an excellent option for ground cover, borders, and bedding. 

When to Sow Mixed Aubreita Seeds 

• Indoor Sowing: Start seeds indoors from late winter to early spring (February to April) to give the plants a head start. 
• Outdoor Sowing: Sow seeds directly outdoors from April to June, once the soil has warmed and the risk of frost has passed. 

Step-by-Step Guide to Sowing Mixed Aubreita Seeds 

Indoor Sowing 

1. Prepare Containers: Use pots or trays filled with a fine, well-draining seed compost. 
2. Sow the Seeds: Scatter seeds evenly on the surface and cover with a fine layer of compost or soil. 
3. Moisture Retention: Cover the pots with cling film or polythene to retain moisture. Remove once seedlings begin to emerge. 
4. Germination Conditions: Maintain a minimum temperature of 15°C to encourage germination. Place the pots in a well-lit location but avoid direct sunlight. Germination typically occurs within 10-14 days. 

Outdoor Sowing 

1. Prepare the Soil: Choose a sunny or partially shaded location with well-draining soil. Loosen the soil and remove weeds before sowing. 
2. Sow the Seeds: Scatter seeds directly onto the prepared soil surface and cover lightly with soil. Water gently to settle the seeds. 
3. Care During Germination: Keep the soil moist but not waterlogged. Germination may take slightly longer outdoors due to temperature fluctuations. 

Transplanting and Care 

• Transplanting: When seedlings are large enough to handle, transplant them to their final growing location, ensuring adequate spacing for their spreading habit. Aim for 12-18 inches between plants. 
• Ideal Growing Areas: Aubreita thrives in baskets, walls, rockeries, and containers. The cascading growth makes it ideal for hanging displays or path edging. 
• Watering: Keep the soil consistently moist, especially during dry periods. Once established, Aubreita is relatively drought-tolerant. 
• Fertilising: A light application of balanced fertiliser in spring can encourage vigorous growth and blooming. Avoid over-fertilising, as this may result in excessive foliage at the expense of flowers. 

Flowering and Maintenance 

• Flowering Period: Aubreita flowers the year after sowing, typically blooming annually from March to late April. 
• Pruning: After flowering, trim back the plants lightly to maintain their shape and encourage dense growth. 
• Overwintering: Aubreita is hardy and can survive UK winters. However, mulching around the base of the plants can provide added protection in colder regions. 

Common Questions About Growing Mixed Aubreita in the UK 

• Can Aubreita grow in shaded areas? Aubreita prefers sunny or partially shaded spots. While it can tolerate some shade, flowering may be less prolific in heavily shaded areas. 

• How do I encourage Aubreita to spread? Aubreita naturally spreads as it grows. Ensure the soil is well-draining and keep it weed-free to promote healthy spreading. 

• When can I transplant Aubreita outdoors? Transplant seedlings outdoors once they are strong enough to handle and the risk of frost has passed, typically between April and June. 

Mixed Aubreita is a low-maintenance yet stunning addition to any UK garden.
