#DC Cherry Blossoms Reach Peak Bloom! The gorgeous pink blooms of the cherry trees that dot the National Mall in Washington D c. have reached finally peak bloom officials announced yesterday (April 9).

) Peak bloom is reached when 70 percent of the blooms on the Yoshino Cherry trees (there are many different types of cherry trees) have opened fully according to the website of the National Cherry Blossom Festival.

The period of peak bloom can last for up to 14 days the site says. The blooming has been delayed this spring because of the cold beginning to the season though that cold could mean the blooms last longer.

Over the long term though global warming seems to be raising March temperatures in D c. these temperatures are a key predictor of

when the cherry blossoms will bloom according to a National park service horticulturalist) and the peak bloom date there is shifting earlier according to an analysis performed by Jason Samenow at the Washington post's Capital Weather Gang blog.

#What's the Cultural Significance of Cherry Blossoms? In 1912 Japan gave more than 3000 cherry-blossom trees to the United states as a gift to honor the growing bond between the two countries.

Now the annual National Cherry Blossom Festival in Washington D c. commemorates this century-old offering of goodwill when the trees bloom each spring.

But what is the cultural significance of cherry blossoms to Japan? Similar to Washington D c. Japan has a yearly flower-viewing celebration called hanami where thousands of people hold feasts under blooming cherry-blossom trees or sakura.

This tradition is over a thousand years old. In Japan cherry blossoms also symbolize the transience of life which is a major theme in Buddhism.

The cherry-blossom tree is known for its short but brilliant blooming season a natural process that metaphorically describes human life.

Additionally cherry blossoms have held long significance to Japanese nationalism and militarism anthropologist Emiko Ohnuki-Tierney wrote in her book Kamikaze Cherry Blossoms and Nationalisms:

The Militarization of Aesthetics in Japanese History (University Of Chicago Press 2002. A fallen cherry blossom symbolizes a fallen samurai who sacrificed his life for the emperor.

During WORLD WAR II the flowers took on a similar meaning when they were painted on the side of kamikaze warplanes.

#Why a Cold Spring Delays Cherry Blossom Blooming It's been a dull spring for cherry blossom watchers so far.

Blossoms in Philadelphia did not open until early April. Usually the flowers appear anywhere from mid-to late March.

when they bloom and it's driven totally by warmth said Paul Meyer executive director of the Morris Arboretum at the University of Pennsylvania.

Also plants on the south side of a building tend to bloom earlier than those on the north side

Given the variability it's always a challenge in scheduling cherry blossom festivals Meyer said.

Stages of Cherry Blossom Blooming Longer blooms Flowers like all biological processes are driven by chemistry. One chemical rule of thumb true in most cases but not always is that for every 18 degrees Fahrenheit (10 degrees Celsius) increase in temperature the amount of chemical reaction taking place say in a plant

This increase in chemistry makes the flowers bloom. During the winter the closed cherry buds can tolerate below-freezing temperatures Meyer said.

So the lingering cold is a signal to the blossoms to stay closed for a while longer as the reactions that will make them bloom aren't yet humming along.

longer-lasting blooms. If exposed to high temperatures say in the 60s or 70s a flower will bloom quickly

and then disappear within four to five days. However a prolonged colder temperature will cause the flowers to slow their blooms making them last between seven and 10 days Meyer said.

Cherry plants are pretty short-lived for trees typically living around 40 or 50 years. Their longevity however depends on the species. There are some types in Japan that have been bred to last more than a century.

But late in 2013 severe rains in central Mexico knocked the blossoms off many lime trees greatly limiting this spring's crop.

This time of year green seems to be everywhere from the warmer weather that encourages spring blooms to St patrick's day to Earth Day.

According to the Centers for Disease Control and Prevention (CDC) boys and girls in this age group should be eating a minimum of one cup of fruits and a cup of vegetables per day.

and now that it's finally warming up trees are expected to bloom at the same time as grasses causing a dramatic rise in pollen allergy experts said.

The images also show traces of phytoplankton blooms in the Great lakes and off the North Atlantic coast.

but unlike most other plants its flowers bloom above ground while its fruits (peanuts) develop below ground.

In order to drive these large algal blooms you need iron says Costa. In fact, he says, the indirect benefits of iron fertilization from whale faeces might remove more carbon from the atmosphere by boosting algal growth than the growth of the whales themselves.

Consequently, the country's numerous lakes, rivers and coastal waters have suffered from repeated outbreaks of algal blooms owing to the excess of nutrients polluting the water.

in which two haploid cells from a single fungus each with one copy of the genome fuse to form the diploid fruiting body (the truffle),

%Excess phosphorus in many of China's lakes, coastal waters and rivers has caused repeated occurrences of harmful algal blooms known as eutrophication.

The blooms consume much of the oxygen dissolved in the water, killing fish and other plant life,

But the meadows and steppes of the Tibetan Plateau are bucking that trend plants are starting to bloom later in spring,

For instance, flowers may bloom one or two months early, says Spevak, which may mean queen bumblebees find less nectar

#Chanel, UCSBS corpse flower, blooms and causes a big stinkchanel UC Santa barbara's corpse flower has finally spread her odiferous wings broadcasting a stench that smells like a cross between rotting flesh and Limburger cheese.

The entire community has been holding its collective breath waiting for UCSB's Amorophallus titanum its proper botanic name to bloom.

but couldn't leave until we saw it in bloom. Discovered in 1878 by the Florentine botanist Odoardo Beccarini the Titan arum another common name given the plant by Sir David Attenborough in his BBC nature documentary series heats up as it blooms

in order to disperse its perfume--hence the moniker Chanel. Heat enables the smell to go farther attracting more pollinating insects

The enormous amount of energy expended during this process limits the time the Titan can bloom which explains why it only blooms for a couple of days

and doesn't bloom annually. Chanel is only the second Titan arum to bloom at UCSB.

Tiny Chanel's mother bloomed once in 2002 before dying. The wait for UCSB's next bloom from this giant Sumatran cousin to the common philodendron may not be as long as the wait for Chanel to bloom.

Chanel is about to become a mother. Staff at the UCSB biology greenhouse had the foresight to contact the U s. Botanic Garden in Washington D c. to secure pollen from its plant (nicknamed Mortimer in social media that bloomed July 21.

Five to seven years down the road Chanel's offspring could possibly bloom. Any seeds that Chanel and Mortimer produce from their cross-continent union will help further conservation efforts for this bizarre majestic and threatened plant Taber said.

while it's in bloom then a few weeks later move on to the next species in bloom.

and causes increases in algal blooms greenhouse gases and insects like mosquitoes that carry disease.

In a symbiotic relationship L. gongylophorous provides food for the leaf-cutter ant Atta cephalotes by developing fruiting bodies rich in fats amino acids and other nutrients.

To fuel production of these fruiting bodies the fungus needs sugar which comes in the form of long cellulose molecules packed inside the leaf clippings the ants deliver.

and even after adoption of the practice by many farmers harmful algal blooms were still occurring in surface waters.

Wetlands and buffers of trees grasses and shrubs help to keep runoff from fields out of the waterways slowing erosion of soil and blooms of algae downstream.

The algae bloom and eventually die and decay removing oxygen from the water. The result is water too oxygen-depleted to support life.#

Ashman and George Meindl coauthor of the study and a Phd candidate in Ashman's lab studied bumblebee behavior using the Impatiens capensis a North american flower that blooms in summer.

The blooms were collected from the field each morning of the two-week study and were of a similar age color and size.
