What it is the common name for Lent Lily

Wild Daffodil
Narcissus pseudonarcissus (commonly known as wild daffodil or Lent lily) is a perennial flowering plant.

This species has pale yellow flowers, with a darker central trumpet.

The long, narrow leaves are slightly greyish green in colour and rise from the base of the stem.

The plant grows from a bulb.

The flowers produce seeds, which when germinated, take five to seven years to produce a flowering plant.

(Sexual [seed] reproduction mixes the traits of both parent flowers, so if garden hybrid cultivars are planted close to wild populations of Narcissus pseudonarcissus, there is a danger that the new seedlings, having hybrid vigour, could out-compete the wild plants.)
