Narcissus asturiensis

Narcissus asturiensis is a perennial bulbous plant native to the mountains of North Portugal and Spain, where it grows at altitudes up to 2000 m (6000 ft). This dwarf Narcissus is 7–12 cm (2.5– 5 in) tall and has small yellow flowers growing singly.

This is a threatened species in the wild, but it is amenable to cultivation.[1] It can be grown as a cold hardy garden plant, needing vernalization (a period of cold weather) in order to flower. As a garden plant, it will bloom in late January or early February at low altitudes.

This plant contains a number of alkaloids including hemanthamine, hemanthidine, tazettine and epimacronine.[2]
