About Angel's Tears Daffodil

Narcissus triandrus · also called Angel's tears daffodil, Triandrus daffodil · flowering

Narcissus triandrus is a delicate, small-growing daffodil native to the Iberian Peninsula and north-west France, typically found on rocky hillsides and open scrub. Each stem carries two to six nodding, cream to pale-yellow flowers with reflexed perianth segments and a neat cup-shaped corona, giving a distinctive pendant appearance. It prefers a sunny, sharply drained site and should be planted in a sheltered rock garden or bulb frame where drainage is impeccable; do not let the bulbs sit in wet soil during summer dormancy. All Narcissus species are toxic to cats and dogs.
