Agapanthus africanus flowers

The inflorescences of Agapanthus africanus are many-flowered umbels of small, lily-shaped flowers on smooth, unbranched peduncles. The pedicels are short. From twelve to thirty flowers make up one umbel.

In bud, the flower tubes are more three-angled than cylindrical, bulging towards their tips before opening. The flowers are deep blue and whitish striped, funnel- or trumpet-shaped, the six tepals in two whorls of three round-tipped or pointed. The open flowers face outwards. The tepal margins in picture are partly crisped. The flowers are from 2,5 cm to 4 cm long. 

In picture the six stamens cohere fairly closely. The straight filaments are white. The small, oblong anthers dark, attached to the filament tips in their mid-areas. 

Flowering happens from late spring to after midautumn (Manning, 2007; Bean and Johns, 2005; iNaturalist; Wikipedia; www.plantzafrica.com).
