Narcissus triandrus, also known as the Angel's Tears daffodil, is a species of flowering plant within the family Amaryllidaceae.
The popular cultivar 'Hawera', belonging to the Triandrus group, has received the Royal Horticultural Society's Award of Garden Merit.[2]
Narcissus triandrus is a bulbous perennial plant. The bulbs of this species are small and dark in colour.[3] Bulbs lay dormant in the soil for the majority of the year until emerging in the Spring. A single bulb usually produces two leaves each that can grow to a length of 20 cm (7.9 in) long by 4–5 mm wide. Leaves are keeled, striate on their surface and sometimes coiled at the tip.[4] Stems of the species are 30 cm (12 in) tall, thick, tubular, and almost waxy on their outer side.[5] Stems can hold from one to six cup-shaped flowers, which are milk white or pale yellow in colour.[4]
Reproduction
The flower size varies, increasing from southeast to northwest, correlating with plant size, probably reflecting a rainfall gradient from the hot Mediterranean climate of the southeast to the cooler, wetter Atlantic climate found in the northwest. Changes in flower size correlate with pollinator fauna, Anthophora species being dominant in the southern population and the larger-bodied Bombus species in the north.[6]
Self-pollination was found to result in significantly lower seed production than in cross-pollination within Narcissus triandrus.[7]
Distribution and habitat
Native to France, Spain and Portugal,[8] where it grows in woodlands, scrubland and exposed mountain habitats in acidic soils.[4]
It has been observed to grow in scrublands, mesophilic grasslands, sandy soils, including some more rocky areas. In Europe, the plant has been spotted in the Iberian peninsula, the Iberian and Aracena Mountains, as well as the Baetic and Penibaetic mountain systems and the Serra de Monchique.
