Although September is the ninth month, “septem” and “septimus” are the Latin words for seven and seventh, reflecting September’s place in the old Roman calendar. September is the first in the string of months between now and the end of the year whose ordinal names differ from their place in the year's order, thanks to the insertion of January and February in the original 10-month calendar.

Beginning of Autumn
In the northern hemisphere, September 1st marks the beginning of meteorological autumn, and is the first of the fall months of September, October and November. The astronomical marker of this season, the autumnal equinox, comes later in the month, on either September 22 or 23. As happened in March with the vernal equinox, the sun once again appears to cross the celestial equator, this time from north to south. Equinox refers to the time when night and day are of approximately equal length.
"The Return of Persephone"

The word autumn derives from the Old French word “autompne,” originally from the Latin “autumnus,” which is of unknown origin. In previous centuries, the season was simply called “harvest,” but as more people left agrarian society to settle in towns, “harvest” became the term for the actual act of reaping while the time of year was more often called autumn. The alternative word for the season, fall, comes from Old English or Old Norse and was short for a weather expression, “fall of the leaf.”

In Greek myth, the goddess Demeter presides over the harvest and fertility. Together, Demeter and her daughter Persephone rule over the seasonal vegetation of the earth. Demeter mourns during the months her daughter spends in the underworld with her husband Hades beginning in the autumn. Her sadness causes the earth to turn cold and barren. When Persephone is allowed to rejoin her mother in the spring, Demeter rejoices and decorates the earth with flowers.

September in the Garden
September may seem like a farewell to summer, but there are still many temperate days ahead in which to enjoy your garden. Beginning with the long holiday weekend, this month is a good time to get caught up on yard chores. Take the opportunity, while temperatures have cooled but a freeze is still weeks off, to divide or transplant hardier perennials, such as hemerocallis, peonies, lilies, salvia and iris. Fall-blooming perennials or those plants with more shallow or delicate root systems are best left to an early spring division. You may want to purchase some colorful mums, pansies, asters and flowering kale to brighten the fall landscape and fill in blank spots left by worn-out annuals.

Labor DayImage
Labor Day, observed on the first Monday in September, is a national salute to the American worker that originated in New York City in 1882. Originally intended as a display of the strength and solidarity of the labor unions, Labor Day has become a widely accepted day of rest. Falling as it does at the beginning of September, Labor Day for many marks the end of summer and the beginning of school, as well as NFL and college football seasons.

September 11
Gardens of Remembrance

Plans for memorials to honor the victims of the multiple terrorist attacks on American soil began to spring up almost immediately after the events of September 11, 2001. Of special interest to gardeners are the Gardens of Remembrance in New York City’s Battery Park. In 2002, the Battery Conservancy commissioned Dutch horticulturist Piet Oudolf to design a 10,000-square-foot perennial garden, intended as a tribute to those who perished and those who survived on September 11. Oudolf, who also designed the stunning prairie plant-filled Lurie Garden in Chicago’s Millenium Park, is known for his interest in plant texture and color, and his careful attention to plant life cycles and changes through the seasons. Oudolf’s design for the September 11 memorial project features some 6,000 plants of 130 different perennial species and native grasses that dance in rhythm to the wind coming off New York harbor.

Higanbana (Lycoris radiata)
At the autumnal equinox, followers of Buddhism in Japan celebrate an ancient festival called Ohigan, meaning “other shore” -- a reference to enlightenment or nirvana. The Japanese weather saying "atsusa samusa mo higan made" translates as "neither heat nor cold lasts beyond the equinox." Ohigan is today a national holiday which people observe by leaving offerings of flowers, food and incense at family tombs. The red spider lily, Lycoris radiata, is a symbol of the fall equinox in Japan, where it is known as “higanbana” or the “flower of the dead.”


The breezes taste

Of apple peel.

The air is full

Of smells to feel-

Ripe fruit, old footballs,

Burning brush,

New books, erasers,

Chalk, and such.

The bee, his hive,

Well-honeyed hum,

And Mother cuts


Like plates washed clean

With suds, the days

Are polished with

A morning haze.

~ John Updike



September Symbols

September’s birthstone, sapphire, is the blue form of the mineral corundum (the ruby is a red corundum). This gem, perhaps because of its color, is associated with the traits of loyalty, truth, faithfulness and sincerity. The name sapphire derives from the Greek “sappheiros” meaning “blue stone.” In ancient myth, the world was set upon an enormous sapphire, whose reflection colored the sky blue.

Symphyotrichum novi-belgii ‘Royal Opal’

September’s birth flower, the aster, is also known in England as the Michaelmas daisy, because its fall bloom time coincides with the September 29 feast day of St. Michael. The fall-blooming asters are typically found in shades of violet and blue, providing an excellent foil for the warm reds and golds of chrysanthemums. The daisy-like blooms of the aster prompted Swedish botanist Carl Linnaeus to name it after the Greek word “astron,” meaning star.

Ipomoea tricolor 'Heavenly Blue'

Morning Glory
This month's alternate birth flower, the morning glory, is a sentimental favorite of many. The trumpet-shaped flowers last for only one day, but one plant will produce many, many flowers. Probably the best known variety is “Heavenly Blue”, but morning glories also come in shades of white, pink and purple and red. The vigorous twining vines begin producing flowers in summer and continue to bloom until stopped by frost.

Myosotis sylvatica ‘Victoria Lavender’

A second alternate flower for the month of September, the forget-me-not or myosotis, is another blue-flowered favorite. This spring bloomer produces petite, delicate flowers of true blue, and makes a good partner for spring bulbs such as tulips, daffodils and hyacinths.
