TextIt seems like an odd moment to be writing about spring and summer wildflowers, what with Old Man Winter hovering on the horizon. But scientists from Harvard and Boston Universities have unsettling news about the impact of climate change on plant life in the New England woods. The researchers have drawn on Henry David Thoreau's detailed records from 150 years ago on the flora around his beloved Walden Pond in Concord, Massachusetts. And they report that some species now flower as much as three weeks earlier than in Thoreau's day because of a 4.3 degree Fahrenheit increase in the mean annual temperature in the Concord area. The bad news is that whole groups of plants have had difficulty adapting to warmer times. Some 27 percent of the species that Thoreau recorded in the mid-19th century are now locally extinct while another 36 percent are so scarce that extinction may be imminent.
TextMore than one-in-four of all flowering plants are under threat of extinction according to the latest report to confirm the ongoing destruction of much of the natural world by human activity. As a result, many of nature's most colourful specimens could be lost to the world before scientists even discover them, claims the research, published today in the journal Proceedings of the Royal Society B.

Cosmos atrosanguineus, commonly called chocolate cosmos, is a type of daisy that was native to Mexico. The chocolate cosmos is extinct in the wild. In cultivation, there is one clone surviving. The chocolate cosmos reached heights of 40 to 60 cm and produced flowers of dark red with a chocolate-like fragrance.
At a certain level of self-consciousness we do not realize how we destroy the planet and the environment by extinguishing different species of plants and animals.
Cosmos atrosanguineus, commonly called chocolate cosmos - I have that in my garden. Neighbour has a HUGE pot of them. Easy to look after and smells lovely. The plants are alive, just not in the place they were originally found.
