Osteospermum 'Tresco Purple', a vibrant cultivar of African daisy, is celebrated for its striking blooms and versatility. Named possibly after Tresco Abbey Garden in the UK, this plant adds a splash of colour to gardens with its daisy-like charm.

Appearance

• Flowers: Rich purple petals radiating from a dark, contrasting centre. Blooms may close at night or on cloudy days, a trait common in Osteospermum.
• Foliage: Glossy, green leaves with a slightly serrated edge, forming a lush backdrop for the vivid flowers.

• Companions: Pairs beautifully with lavender, sedum, or grasses. Contrast with yellow coreopsis or orange marigolds.
• Wildlife: Attracts pollinators like bees and butterflies, enhancing garden biodiversity.

Potential Challenges

• Pests/Diseases: Watch for aphids and powdery mildew. Slugs may be an issue in damp areas.
• Environmental Stress: Avoid overwatering to prevent root rot. Not suited for high humidity or heavy clay soils without amendment.
