Haldena

Haldena is a genus of plants in the family Asteraceae. The genus was described by Carl Linnaeus in 1753 and is native to the Americas. Haldena species are typically herbaceous perennials, though some can be annuals. They are characterized by their composite flowers, which are made up of many small florets. The petals are usually white or yellow, and the center of the flower is often brown or black. The leaves are typically alternate and toothed or lobed.

The genus Haldena contains several species, including Haldena annua and Haldena perennis. Haldena annua is an annual plant that is found in disturbed areas and along roadsides. Haldena perennis is a perennial plant that is found in meadows and prairies. Both species are important components of their respective ecosystems, providing food and habitat for a variety of wildlife. The reproductive strategy of Haldena involves pollination by insects, with seeds dispersed by wind or animals. Conservation status varies among species, with some considered common and others facing threats due to habitat loss.
