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 bulbs are produced to satisfy the demand for bulbs for parks, gardens and as house plants, in addition to providing the bulbs necessary for the production of cut flowers. The international trade in cut flowers has a worldwide value of approximately 11,000 million Euros, which gives an idea of the economic importance of this activity.
The family is commonly known as the aster, daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be annual, biennial, or perennial, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions, in a wide variety of habitats.
Few insects are as beloved as the monarch butterfly. These fascinating creatures are beautiful, boldly colored and surprisingly strong — the North American monarch migrating thousands of miles ...
Flowering plant bulbs are planted beneath the surface of the earth. The bulbs need some exposure to cold temperatures for 12 to 14 weeks in order to bloom. [1] Flower bulbs are generally planted in the fall in colder climates. The bulbs go dormant in the winter but they continue to absorb water and nutrients from the soil and they develop roots ...
Monarch butterflies flying and sipping nectar from milkweed flowers. The adult's wingspan ranges from 8.9 to 10.2 centimetres (3.5 to 4.0 in). [10] The upper sides of the wings are tawny orange, the veins and margins are black, and two series of small white spots occur in the margins. Monarch forewings also have a few orange spots near their tips.
Monarch butterflies are thought to respond to different cues that promote the fall season southern migration. These include the angle of light coming from the sun, the senescence of larval host milkweed plants, the decreasing day period and temperature drop. [21] The migration begins at the northernmost summer range approximately in August.
