Yellow Daisies
Most yellow daisies are very tough and easy perennials which are bright in the garden and long-lasting in a vase; bringing a wide range of styles to sunny situations.
Rudbeckia fulgida, the orange coneflower or perennial coneflower, is a species of flowering plant in the family Asteraceae, native to eastern North America.
It is an herbaceous perennial growing up to 120 cm (47 in) tall, with bright yellow daisy-like composite flower heads.
Growth and reproduction
In the garden, this plant spreads aggressively by both stoloniferous stems and seed. The seeds are produced in fruits called cypselae, which are 2.2 to 4 mm long and have short coroniform pappi, 0.2 mm long. The ripe seed is a favorite food of finches in winter.
Morphology
Stems are hairy, ridged, and dark green. Leaves are dark green, sparsely but roughly haired, simple, with sparsely serrate margins. Flowers are heads, with black disk florets and bright orange ray florets, borne singly on stems that extend above the foliage. Stems are glabrous or moderately covered in hirsute hairs with spreading branches. The leaves have blades that are lanceolate to broadly ovate or elliptic in shape without lobes. The leaf bases are attenuate to cordate in shape and the margins of the leaves are usually entire or serrate, or sometimes lacerate. The upper surfaces of the leaves are glabrous or have hirsute to strigose hairs. The basal leaves are petiolate, with petioles that are 5 to 30 cm long and 1 to 8 cm wide, the cauline or stem leaves have petioles that are 2 to 25 cm long and 0.5 to 7 cm wide, the bases are attenuate to cordate or auriculate in shape.
The flower heads are often produced one per stem but are also often produced in corymbiform arrays with 2 to 7 flowers per stem. The cups that hold the flowers called receptacles, are hemispheric to ovoid in shape with paleae 2.5 to 4 mm long, the apices are obtuse to acute in shape with the ends usually glabrous and the apical margins ciliate. The flower heads have 10 to 15 ray florets with laminae elliptic to oblanceolate in shape and 15–25 cm long and 3 to 6 mm wide. The abaxially surfaces of the laminae have strigose hairs. The flower discs or center cones are 12 to 16 mm tall and 10 to 18 mm wide, made up of 50 to over 500 disc florets, with the corollas proximally yellowish green and brown-purple distally in color, 3 to 4.2 mm long, having style branches 1.3 mm long.
This fine display was at Legoland Windsor Resort, also known as Legoland Windsor, which is a child-oriented theme park and resort in Windsor, Berkshire in England, themed around the Lego toy system. The park opened in 1996 on the former Windsor Safari Park site as the second Legoland after Legoland Billund in Denmark. In common with the other Legolands across the world, the park's attractions consist of a mixture of Lego-themed rides, models, and building workshops. The park was acquired by Merlin Entertainments in 2005, which now operates the park, with the Lego Group retaining part ownership (30%). The facilities are mainly targeted at children between three and twelve.
In 2015, the park had 2,250,000 million visitors, making it the most visited theme park in the United Kingdom and the 9th most visited in Europe.
