MYSTERY PLANT: Wildflower blooms in summer for as long as it can
Nov 3, 2018In this case, all of the flower parts appear to arise at the very end, or apex of the ovary, and so the ovary is in a position below or inferior to the floral parts.
Other plants exhibit an alternative "superior" ovary, with the floral parts at the base of the ovary. A good example would be what happens with a tomato flower.
The tomato, as it swells, has a “blossom end” where it is attached to the flower. The position of the ovary, from species to species, is very important in separating different plant families.
Once pollination has occurred, the ovary of our mystery plant elongates considerably, often swelling somewhat toward the end. Plenty of tiny, pale tan seeds will be produced, and these will fall away once the matured ovary, now a capsule, splits open.
This plant is common in wet places, often in ditches or at pond edges or other marshy spots. It's found from Maryland to West Virginia and well into southern Florida, as well as Texas and the lower Midwestern states. It has plenty of near relatives, many of which are most common in South America.
Some of these are reasonably aggressive and are considered serious pests in wetlands. Otherwise, it is more distantly related to some very popular ornamental plants, including evening-primrose, as well as the cultivated fuchsias. This yellow-blooming wetland herb probably won't win many competitions in the flower shows, but it's nice to see on a mid-autumn day, bravely blooming up to the bitter end.

Nepal's commercial flower output worth Rs671m
Sep 28, 2018The sector provides employment to 2,300 people on a permanent basis and to 72,400 people on daily-wage basis.
This is the first time the government’s apex statistical authority has carried out a national level census in the floriculture sector.
The country produces seasonal flowers like marigold and dahlia, among others, worth Rs221.74 million annually, the CBS said.
Perennial flowers make up the second largest production. The country grows perennial flowers like rose, chrysanthemum, carnation and azalea worth Rs167.09 million annually. The third on the list of most widely produced flowers is decorative flowers. Nepal produces decorative flowers such as dhupi (Himalayan Cypress), shrubs used in hedge and erica, among others, worth Rs120.37 million.
Similarly, cut flowers, loose flowers, garden dubo (commonly called Bermuda grass) and flowers produced through seeds, rhizome and bulb are also among the most widely produced flowers in Nepal.
Unveiling the report on Monday, Nebin Lal Shrestha, deputy director general of the CBS, said Nepal had immense potential in producing these flowers due to the diverse climatic conditions and geographical structures. “The country can benefit from expanding commercial farming of these flowers through import substitution,” he said.
According to the CBS, it has considered growing flowers on at least 8 annas of land in the hilly and mountainous regions as commercial
farming. In the Tarai, the CBS has set the threshold for commercial farming at 10 dhurs of land.
The CBS said it conducted the study in two phases—identifying the distric... http://kathmandupost.ekantipur.com/news/2016-09-27/nepals-commercial-flower-output-worth-rs671m.html
Sunflowers dance under the sun to increase growth, says scientists
Sep 28, 2018The higher growth rate on the east versus west side of the stem during the day enables the shoot apex to move gradually from east to the west. At night, the higher growth rate on the west side culminates in the apex facing east at dawn.”

A young sunflower plant not only tracks the sun during the day but also reorients at night in anticipation of dawn.
Mature sunflowers respond differently to the sun as it has achieved its full growth and the researchers compared mature flowers facing east with those they turned to face west, and found that the east-facing blooms attracted five times as many helpful pollinators.
“Just like people, plants rely on the daily rhythms of day and night to function,” says Anne Sylvester, director of the National Science Foundation’s Plant Genome Research Program.
Hence, young sunflowers actually dance as each day, when they trace the path of the sun across the sky, turning their faces 180 degrees from east to west.

And their slow, graceful movements continue at night. After the sun sets they reorient themselves, slowly twisting their heads back to the east in anticipation of dawn.
