flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

You're probably familiar with the sight of a lillipilly bush. This hardy Australian staple—a glossy evergreen bearing powder-puff flowers and clusters of bright berries—features in many a garden hedge.
- Hidden microbiome fortifies animals, plants tooon September 29, 2022 at 8:40 pm
The microbiome is the collection of microbes that colonize a habitat, human body or otherwise. Because of pioneering microbiome research at Washington University School of Medicine in St. Louis, people around the world now understand much more about the fundamental role of gut microbes in human health and disease.
- Ozone pollution threatens plant health and makes...on September 29, 2022 at 3:00 pm
Over the past decades, rising levels of ozone pollution have been interrupting pollination, impacting the livelihood of both plants and the animals that pollinate them. In a review published September 29 in the journal Trends in Ecology and Evolution, researchers explain how an excess of ground-level ozone can damage plant foliage, change plants' flowering patterns, and act as a barrier to pollinators finding blooms.
- A new window into plants of the paston September 28, 2022 at 10:09 am
Within the cabinets and drawers of the world's herbaria are nearly 400 million dried plant specimens. These collections have long served as a vital record of what plant species exist on Earth and where they grow. But hidden within the desiccated leaves, stems, flowers and roots is far more information on how the plants interacted with their environment while they were alive. Knowing about these "functional traits"—aspects like leaf structure, chemical composition and water content—could […]

Spring has arrived in Australia's Snowy Mountains. The snow is starting to melt. Wildflowers are emerging in a variety of colors: blues, yellows, whites … hang on. Those aren't white flowers. They're scrunched up bits of toilet paper left behind by skiers, boarders and snow-shoers.

Researchers at the University of Freiburg have found that hedges and perennial flower strips are complementary in supporting wild bees in orchards by providing continuous resources over the growing season. The results are published in the British Ecological Society's Journal of Applied Ecology.
- Tracking the origin of southern California's...on September 23, 2022 at 5:59 pm
In 2012, a crop of California's most prized ornamental trees was overrun by an invisible invader. The growing shoots of coral beans—the official city tree of Los Angeles—began wilting and falling away, revealing stems that had been hollowed out from the inside by the caterpillars of Erythrina stem borer moths.
- Higher temperatures make it difficult for fig...on September 23, 2022 at 5:25 pm
Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.
- To reach net zero the world still needs mining....on September 23, 2022 at 4:30 pm
On the wooded hill above the Stan Terg lead and zinc mine in Kosovo, there is an old concrete diving platform looming over what was once an open-air swimming pool. Before the break-up of Yugoslavia, people who worked at the mine would bring their families here to swim, sunbathe on the wide terrace with its view across the valley, and picnic among the trees. Now the pool is slowly disappearing into the forest, the view obscured by birch saplings.
