About Narcissus bulbocodium L.
Narcissus bulbocodium L. is a variable, small, hardy bulbous perennial plant. It grows 10–15 cm (4–6 in) tall, produces grass-like leaves, and bears deep yellow trumpet-shaped flowers in mid-spring. The flower of this species is unusual because its central trumpet, called the corona, is exceptionally large relative to the outer section, which is called the perianth. The perianth is made up of tiny pointed segments. The specific epithet 'bulbocodium' translates to 'woolly bulb'. Among all recognized Narcissus species, it has the smallest floral diameter, measuring just 12 mm across.
In cultivation, Narcissus bulbocodium L. is widely planted in gardens and can be naturalized in grassy areas. It needs relatively dry conditions during its summer dormant period, so it grows well when planted beneath deciduous trees. Numerous varieties and cultivars of the species exist, including N. bulbocodium subsp. bulbocodium var. conspicuus, which produces pale yellow flowers, and 'Golden Bells', a vigorous cultivar with long-lasting deep yellow flowers. Narcissus bulbocodium L. has been awarded the Royal Horticultural Society's Award of Garden Merit.
