We did not plant this sunflower--probably some bird or rodent did. Whatever they did, it seems to have worked, this plant is about

The handsomest sunflower
Aug. 8th, 2014 09:23 pm
This was, I decided, the handsomest of all our sunflowers. We have a small group of them, some of which have collapsed at the base and are yet crawling along the grass. This one is pretty spectacular.

Besides the delicious pollen and nectar, the sunflowers provide a needed resting place for the bumblebees.
Treehopper roundup!

This robber fly has rounded himself (herself maybe) up a thorn-mimic treehopper. They're probably sweet and delicious.

On the underside of a nearby sunflower leaf, some unidentified treehopper nymphs group together waiting for ants to tend and guard them. Am I right? Lumpy and homely. But kind of cute.
100 Species #70: Sunflower

This sunflower Helianthus annuus is part of a little garden of the flowers Alexis planted this year, in the corner of the side yard.
Sunflowers have always been my favorite cultivated flower, because they are simple and big, and they are named for and symbolize my favorite thing in the sky. It's something of a coincidence that big disk surrounded by yellow ray flowers looks so much like our two dimensional representation of the day star. But it's a nice symmetry, especially the way the big disk faces east to "look at" the ball of gas that gave it life.
Sunflowers are native to the New World, domesticated and carried to North America long before European colonization. They are cultivated in the plains states in massive plantations for their seeds and oil, and for potted or cut ornamental flowers. Wild sunflowers grown from seeds cached by birds and rodents are often encountered. There are 50 or so relatives in the genus, all found in North America, and all bearing the common name "sunflower" except for the "Jerusalem artichoke" which has appeared in this blog, probably as a slight misidentification.
Predation on the flower by chipmunks cures some people of their belief that these animals are cute, while others simply make sunflower seeds available to them. The use of sunflower seeds as an artificial winter food source has probably contributed to the expansion of the range of several songbirds, such as cardinals, titmice, and others that were not in New England before the 20th century.

Urban Nature Pictures 9/22

Alexis amid the sunflowers and phragmites. I took a very similar picture almost exactly one year ago.

This polypore was growing on the dirt nearby. Hidden in the soil is the wood of a long-dead tree. If the tree was a broadleaf, this mushroom is Ganoderma lucidum; if it was a conifer, the mushroom is G. tsugae.

Urban species #232: Sunflower Helianthus annuus
Sunflower seeds are relatively large, fatty, and tasty. They are the staple filling for most birdfeeders. With a feeder full of sunflower seeds in Boston, you can attract chickadees, nuthatches, downy woodpeckers, blue jays, house sparrows and squirrels, just for starters. The presence of feeders full of sunflower seeds lured formerly more southern species like the cardinal and titmouse to live in New England year-round. These animals spill the sunflower seeds on the ground, where they are eaten by pigeons, mourning doves, juncos, chipmunks, and if you live in the right neighborhood, wild turkeys and even white-tailed deer. In other cities there will be some other assemblage of urban species drawn to this food source. Some of these species, notably the jays and woodpeckers, carry the seed away, and cache it to be eaten later. Uneaten seed may germinate and result in "volunteer" (to use a nice bit of gardener jargon) sunflowers.
The plant itself is familiar to all: a single rough stalk topped with a large cheery disc surrounded by rays, facing the sun, and appearing to have been crafted in its image. It is native to western North America, where the indigenous people cultivated them, favoring the plants with the biggest seeds. It was brought to Europe, where further cultivation took place, and new varieties were reintroduced to North America. Industrial cultivation for flowers, seeds, and seed oil has helped make it well known to nearly everyone on earth. There are many different species, but the most familiar, and most often cultivated species is the common sunflower, Helianthus annuus.
Wild sunflowers can grow to nearly ten feet tall, hoisting their payload of seeds up to where only the most agile diners, often goldfinches, can reach. Squirrels will cheat, and chew the whole plant to the ground. The plant must reproduce by seed, and is an annual, dying away completely in winter. Then the birdfeeders are filled and put out, and the urban life cycle starts again.

A sunflower seed cached in a stone wall (in the Riverway, in the wall of the stairway leading to Longwood Ave.) sprouted in June of this year. The plant did not survive to flower. Photo by
