Despite taking many precautions during sowing, no germination! Total failure.

Description

Agapanthus Headbourne hybrids is undoubtedly the most cold-resistant variety (to -15°C (5°F)), especially in well-drained soil. It opens its large umbels of intense blue in July/August, as early as the second year of cultivation, on a tuft of light green ribbon-like foliage that spreads over time. This undemanding plant with a very exotic appearance is ideal for giving a holiday and seaside touch to balconies, terraces, and flower beds. Its faded inflorescences remain decorative on the plants in winter. It must be grown in full sun, in rich, well-drained, moist to dry soil.

 

This vigorous and hardy hybrid agapanthus belongs to the lily family and descends from different species of South African origin, including the Agapanthus campanulatus, which is quite tall and native to the Natal province.

Plants from the Headbourne Hybrids mix develop from a short rhizome with fleshy roots. They form a dense tuft composed of short and wide light green ribbon-like, deciduous leaves. When in bloom, they easily reach a height of 80cm (32in) and a width of 60cm (24in), much more over time. In the heart of summer, solid floral stems appear, crowned with intense medium-blue, 12cm (5in) umbels of 20 to 50 flowers. This bulb is hardy down to about -15°C (5°F) with winter protection, but many specimens have endured even lower temperatures.

 

The Headbourne hybrid agapanthus is useful in the background of flower beds or to highlight the layout of pathways. It blends well with all types of decor, even the most modern, as long as they are bathed in sunlight. It can be placed in large pots on the terrace, in a pretty wide pot that will allow this plant to produce numerous floral stems. Growing in pots makes it easier to store during winter. It thrives by the seaside, in an English cottage, and even in a city garden. Cut and placed in a vase, the flowers will bring freshness and originality to the house. Left in place, the faded inflorescences will decorate the dormant flower beds in winter.

Planting and care

Sow from late winter to spring in a specialised sowing compost, barely covering the seeds. Keep the soil moist but not waterlogged. It is useful to enclose the sowing in a polythene bag. Germination usually takes 1 to 3 months at 15-18°C (59-64.4°F).

When the seedlings are large enough to handle, transplant them into 7.5 cm (3in) pots, then later into 13 cm (5in) pots. Overwinter them in a frost-free greenhouse. The following spring, gradually acclimatise the young plants by exposing them to outdoor conditions for 10 to 15 days before final transplantation into the ground. This should be done once all risk of frost has passed. Bury the crowns 5 cm (2in) deep and 38 to 45 cm (15 to 18in) apart. Choose a sunny location with fertile, deep, well-drained soil.

 

Cultivation: Agapanthus grows in full sun in warm, sheltered, south-facing locations. Plant it in rich, moist, but very well-drained soil to optimise its hardiness. Water agapanthus regularly during the growing period (twice a week), but not in winter. Mulch the base of the plants with a 20 cm (8in) layer of dead leaves covered with a mesh to prevent wind damage. Snow also provides excellent protection against excessive moisture and cold. In containers, bring the plant indoors to an unheated space to protect it from severe frost. When planting, use a mixture of leaf compost and soil. Once established in the ground, avoid disturbing agapanthus. Remove faded leaves in autumn. You can trim the flower stems to prevent the plant from wasting energy on seed production.
