The habitat of this plant is pastures, copses, orchards, etc, where no doubt it has been planted. It differs from the ordinary daffodil in being more robust, frequently with double flowers, with the perianth segments broader, the corona being lemon-yellow, with 6 rounded lobes. It is 12-18 in. in height, and is in flower from March till May. The Spanish Daffodil is a herbaceous perennial.
This species is a native of Europe, the Pyrenees, etc, and has been recorded from Cornwall, but is not a native plant, being an escape from cultivation only. The leaves are semi-cylindrical, there being two on the spathe, and the three flowers are yellow, sweet-scented. The crown has 6 deep lobes of a deep yellow.
The habitat of this plant is sandy fields. The outer scales of the bulbs are membranous. The habit is grass-like or lily-like. The leaves are long, acutely keeled, linear, blunt, not bluish-green, the margins turned back. The scape is flattened, as long as the leaves, 2-edged.
The perianth is broad, with white or pale yellow-coloured flowers, in pairs (hence the Latin specific name), the margin bent inwards. The tube is slender, sabre-shaped, the flower-stalk slender. The 6 perianth-segments are blunt and egg-shaped. The crown is pale yellow, scalloped, short, hollow, the margin pale then white. This Narcissus is 1-1 1/2 ft. in height. It is in flower in April and May, and is a herbaceous perennial.
This plant is found in fields, or heathy open fields. The habit is similar to that of the Daffodil. The leaves are rather blunt, keeled, and linear. The scape bears one flower as a rule, and is flattened at the border, being 2-edged. The petals are broadly egg-shaped, white, with a yellow crown, which is hollow above, short, with a scalloped red border (hence the English name). The plant is from 1 ft. to 18 in. in height. The Pheasant's Eye blooms in May, and is a herbaceous perennial.
The Snow-flake is found in wet meadows and by stream sides, in osier beds. The habit is erect, the bulb 1 in. long. The leaves are produced at the same time as the flowers. They are keeled, blunt, rather bluish-green, and linear. The long scape is 2-edged, with a spathe with many white flowers, the tip green and entire. The flower in bud is erect, drooping when open, and is bell-shaped, the flowers in clusters of 2-6. The petals are egg-shaped, green at the tip. The style is thicker above. The fruit is conical. The seeds have no caruncle. The height is 2-2 1/2 ft. Flowers may be gathered in May, and the Snowflake is a herbaceous perennial.
