Where we live, the wild daffodil Narcissus pseudonarcissus grows in profusion, its chrome yellow trumpets surrounded by pale primrose perianths

The segments of the perianth
are yellow with bright red bases, and the fruits are oblong, 3-6 cm long, reddish to purplish-red when mature.
Each flower is borne in a single bract (modified leaf) and has either no perianth
(floral envelope) or one reduced to a series of scales or bristles rather than showy petals.

However, aesthetically, its rare ivory white perianth
(petals) and two coloured corona (trumpet) in both amber-orange and buttermilk white, means that Alnwick Magic will always be distinctly visible in its striking clusters to both visitors and gardeners alike.
The individual unisexual flowers lack a perianth
, the pistillate flower consisting of 1 (rarely 2) pistil(s) subtended by a scale, and the staminate flower consisting of 1-3 stamens borne in a scale.

After separating the perianth
parts and stamens, stigmas with three parts were collected and weighted on an analytical scale.

Like nearly all other Nyctaginaceae, the fruit is an achene, surrounded by an "anthocarp," a persistent accessory fruit that develops from the lower part of the uniseriate perianth
