Cornucopia: Origins by Carol King

Cornucopia Photo
The cornucopia is the symbol of abundant harvest and is most often associated with Thanksgiving in the United States. It is a horned shaped vessel filled with an abundance of the earth's harvest. 

Cornucopia became an English word in 1508 when it first appeared in the dictionary. Its origins are from two Latin words; Cornu meaning "horn" and Copia meaning "plenty". 

The cornucopia has been a symbol of a great harvest for centuries and was probably first referred to in Greek and Roman myths and dates back to the 5th century B.C. My favorite is the Greek version: “ Almathea was a goat who nursed and raised Zeus. While playing one day, Zeus accidentally broke one of her horns. He was so saddened by this that he used his godly powers to fill the broken horn with whatever Almathea wanted so it became the horn of plenty. Zeus also put the goat's image in the sky and that is our constellation Capricorn.”

The symbol of the cornucopia was also used, along with rolling fields of grain, to lure new settlers to come to the New World. It is now in our national consciousness as a symbol for bountiful garden harvest and the sharing of food that has become our American Thanksgiving.  

Wishing you and yours a harvest of good food and good fortune! Happy Thanksgiving.

Pines Shedding Needles is Normal by Carol King

Photo by Carol King
Are your pine trees dropping their needles? There is no cause for alarm; they are probably naturally losing their needles. Everyone knows that deciduous trees lose their leaves in the fall, but fewer people learn that evergreen trees also lose their old needles in the late summer and  fall. Evergreens normally do shed previous years' needles on a regular basis. Often there can be a "heavy" needle drop on Front Range landscape pines, spruces and firs. The most common causes of excessive needle drop are too-wet and too-dry soils. We have had both this year!

There may be a problem if there is yellowing or dieback on the tips of branches. Consider drought, salts, root damage, spray damage, soil compaction, conifer aphids, mountain pine beetle and other factors. Occasionally, "deciduous conifers" such as bald cypress, larch and dawn redwood are found in Colorado landscapes. These conifers lose all their needles every autumn, to be replaced the following spring.

My Houseplants Have the Winter Yellows by Rebecca Anderson

Peace Lily, Spathiphyllum sp., with a yellow sun leaf

I take most of my houseplants outside every summer.  They seem to enjoy a few months on the patio, growing a multitude of lush leaves in the more direct sunlight.  Then in the fall as the nights cool off, I bring them back in the house.  After the transition, I notice several of the leaves become yellow and dry up.  I'd like to think they're mourning the passing of another summer, but really they are going through a normal physiologic process to streamline their metabolism for the lower light conditions inside the house.

Wayward Weeds or Red Root Pig Weed by Ann Moore

Amaranths retroflorus photo from
       The term weed is sometimes slang for marijuana but since that chapter is not finished yet, we will just accept Merriam Webster’s definition:  a weed is a plant not valued in the place is is growing and is usually of vigorous growth, especially one that tends to choke out more desirable plants.

This covers lots and lots of plant growth (a lovely little petunia in an onion patch?).  But the one we really should hope to find a good use for soon is Red Root Pigweed, scientific name Amaranths retroflexus.

Amaranth is a lovely nourishing seed that has been around for literally hundreds of years.  There are recipes for all kinds of delicious sounding things made with amaranth seeds.

Gourd Birdhouses by Donna Duffy

It’s gourd harvesting time! There are two basic types of squash that are grown and used decoratively: 1) Cucurbita or soft-skinned gourds – these are the colorful orange, gold and green gourds that look like small squash and come in odd shapes; 2) Lagenaria or hard-skinned gourds – these larger, utilitarian gourds include the familiar Birdhouse, Bottle and Dipper gourds. Hard skinned gourds grow green on the vine and eventually turn shades of tan and brown.

Sow Native Plant Seeds Now! By Donna Duffy

You still have time to sow native plant seeds in your garden. Mid to late fall is a good time to sow native seeds because subsequent winter cold and snow will promote seed germination next spring. If you are unsure where to purchase native plant seeds, check out the Colorado Native Plant Society’s publication: Native Plant Vendor List.
