How to Grow Osteospermum ‘Tresco Purple’
Osteospermum ‘Tresco Purple’ is a stunning African Daisy variety that produces masses of deep purple flowers from late spring through to autumn. Its compact habit makes it perfect for borders, containers, patio displays and coastal gardens, where it thrives in full sun and well-drained soil.
Where to Plant Osteospermum ‘Tresco Purple’
For the best display, plant Osteospermum ‘Tresco Purple’ in a sunny position receiving at least six hours of direct sunlight each day. This variety performs particularly well in raised beds, gravel gardens and patio containers where drainage is excellent.
Soil Requirements
Osteospermums dislike sitting in wet soil, especially during winter. Plant in well-drained soil improved with compost and grit if needed. When growing in pots, use a quality multipurpose compost mixed with perlite or horticultural grit to improve drainage.
Watering and Feeding
Water regularly while plants establish, then reduce watering once growth is strong. Osteospermum ‘Tresco Purple’ is drought tolerant and generally prefers slightly drier conditions. Feed every few weeks during the growing season with a balanced liquid fertiliser to encourage continuous flowering.
Deadheading and Care
Removing faded flowers will help keep plants tidy and encourage fresh blooms throughout summer. If flowering slows, lightly trim back the plant to promote a new flush of growth and colour.
Winter Care
In mild coastal areas, particularly in the South West, plants may survive outdoors with winter protection. Elsewhere they are often grown as annuals or moved into a frost-free greenhouse or conservatory for winter. Taking cuttings in late summer is an easy way to preserve plants for the following year.
Pests and Problems
Osteospermum ‘Tresco Purple’ is generally trouble-free. Occasionally aphids may appear on new growth, while overly wet conditions can lead to root problems. Good airflow and free-draining soil are the best preventive measures.
