Xerochrysum bracteatum, commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as Helichrysum bracteatum for many years before being transferred to a new genus Xerochrysum in 1990.
The leaves are alternate, trifoliate (with three leaflets), each leaflet 15–30 mm (5 ⁄ 8 – 1 + 1 ⁄ 8 in) long and 8–15 mm (3 ⁄ 8 – 5 ⁄ 8 in) broad, green with a characteristic pale crescent in the outer half of the leaf; the petiole is 1–4 cm (1 ⁄ 2 – 1 + 1 ⁄ 2 in) long, with two basal stipules that are abruptly narrowed ...
A Gazania rigens flower with closed petals in the early evening.. Gazania rigens is a spreading, low-growing, half-hardy perennial, growing to 50 cm (20 in) tall and wide, with blue-grey foliage and brilliant yellow, daisy-like composite flowerheads throughout the summer.
Ranunculus acris is a herbaceous perennial plant that grows to a height of 30 to 100 cm, with ungrooved flowing stems bearing glossy yellow flowers about 25 mm across. There are five overlapping petals borne above five green sepals held upwards against the petals, that turn yellow as the flower matures.
Like other goldenrod species [17], the leaves and inflorescences of tall goldenrod are widely used as a natural dye. Depending on the use of mordants [ 18 ] , the growing conditions of the plant, and whether the plant is subject to gall-inducing herbivores [ 19 ] , colors range from bright yellow to deep olive green.
Hieracium or hawkweeds, like others in the family Asteraceae, mostly have yellow, [11] tightly packed flower-heads of numerous small flowers [8] but, unlike daisies and sunflowers in the same family, they have not two kinds of florets but only strap-shaped florets, each one of which is a complete flower in itself, not lacking stamens, [11] and joined to the stem by leafy bracts.
The opening to the flower is hairy. A highly variable plant, taking many forms, E. guttata is a species complex in that there is room to treat some of its forms as different species by some definitions. [9] The plant ranges from 10 to 80 centimetres (4 to 31 + 1 ⁄ 2 in) tall with disproportionately large, 2 to 4 cm long, tubular flowers. The ...
