From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life. New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming...

Most flowering plants, equipped with both male and female sex organs, can fertilize themselves and procreate without the aid of a mate. But this may only present a short-term adaptive benefit, according to a team of researchers led by two University of Illinois at Chicago biologists, who report that long-term evolutionary survival of a species favors flowers that welcome pollen from another plant. "We've shown that a strong, short-term advantage experienced by individuals that have sex with...

Florida case study contains recommendations for educators A new trend shows native wildflowers are becoming more popular with consumers. The wildflower seed industry has experienced gains in popularity over the past 30 to 40 years and is considered to be a maturing, highly competitive market. In Florida, for example, a 2005 survey estimated sales of native plants in the state totaled almost $316 million. College students do not fit the traditional demographic profile of gardening and...

Patterns of flower biodiversity point to the importance of having 'room to grow' What, in nature, drives the incredible diversity of flowers? This question has sparked debate since Darwin described flower diversification as an 'abominable mystery.' The answer has become a lot clearer, according to scientists at the University of Calgary whose research on the subject is published today in the on-line edition of the journal Ecology Letters. Drs. Jana Vamosi and Steven Vamosi of the Department...

A call to action for a growing world Earth-friendly perennial grain crops, which grow with less fertilizer, herbicide, fuel, and erosion than grains planted annually, could be available in two decades, according to researchers writing in the current issue of the journal Science. Perennial grains would be one of the largest innovations in the 10,000 year history of agriculture, and could arrive even sooner with the right breeding programs, said John Reganold, Washington State University (WSU)...

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

New research confirms that early angiosperms were weedy, fast-growing Fossils and their surrounding matrix can provide insights into what our world looked like millions of years ago. Fossils of angiosperms, or flowering plants (which are the most common plants today), first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, it is thought that early angiosperms must have been weedy, fast-growing shrubs and herbs found in highly...

Findings fuel ongoing debates over different approaches to dating the tree of life Flowering plants may be considerably older than previously thought, says a new analysis of the plant family tree. Previous studies suggest that flowering plants, or angiosperms, first arose 140 to 190 million years ago. Now, a paper to be published in the Proceedings of the National Academy of Sciences pushes back the age of angiosperms to 215 million years ago, some 25 to 75 million years earlier than either...

The origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers. A study appearing online this week in the Proceedings of the National Academy of Sciences unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of the major moments in plant evolution, when the ancestors of most of the world's flowering plants split into two major groups. Together the two groups make up...

Flower garden
2013-08-21 08:27:49

Flower gardens, used for beautification purposes, contain various flowering plants providing blooms all year long and can be elaborate or simple. Flower gardens come in all shapes, sizes, and colors. Formal flower gardens are planned out and serve as a multi-function garden, such as growing herbs around the border of a flower garden with edible blooms. Shrubs are also used in creating flower gardens suitable for plants requiring shade. A haphazard flower garden is one that is allowed to...

Perennial Plant
2013-04-27 08:01:21

Perennial plants live for two years or more. Perennials differ from annuals and biennials with annuals replanted every year and biennials every other year. Perennial’s that bloom during spring and summer will die back in autumn, rest during the winter, then re-grow the following spring from the existing root-stock; these are also known as deciduous perennials. If the climate is continually warm, a perennial will continually grow and produce flowers and or fruit. A perennial relocated from...

Biennial Plant
2013-04-27 07:50:37

Biennial plants have a two year life cycle; roots, stems and leaves in the first year with flowers following the next year after a cold winter dormant period. Biennials will produce seed and fruit before dying. There are not as many biennial plants as there are perennials or annuals. Biennial plants, when exposed to extreme climate conditions, may have a shortened life cycle of a few months especially if the plants were exposed to colder than normal temperatures. Most biennials can be...

Annual Plant
2013-04-27 07:44:51

Annuals are plants that flower and/or set fruit in one growing season. Most vegetables are annuals as well as domesticated grains. Vegetables such as carrot and celery are biennials grown as an annual whereas tomato and bell pepper are perennials and grown as an annual. Annuals grow well mixed in with perennials and biennials. There are also ornamental flowers that are perennials in one region and an annual in another. An annual can produce seeds that continue the life cycle in as little...
