“Big Old Squash” (Gete-okosomin) Winter Squash
About an hour’s drive northwest of Green Bay, Wisconsin in the land of the Minominee Tribe, a tiny clay pot was discovered by archaeologists. The clay pot was nothing out of the ordinary, but its contents revealed a gift that will live on for generations to come. The 800 year old seeds of an extinct squash lay inside. The whimsy of this story is captivating, unfortunately it is most likely untrue.
The variety of squash reported in this tale comes from the saved seed of members of the Miami Nation of Indiana. The seeds were gifted to David Wrone, an emeritus professor at the University of Wisconsin. Although the seeds have not been stored underground in a clay pot for 800 years, they have been grown and saved by the Miami Nation for more than 5,000 years.
The squash named Gete-okosomin (meaning “Big Old Squash” in the Menominee language) is a variety of winter squash (Curcubita maxima) that can grow up to 30 pounds. It has been reported to have a much thinner rind than most winter squash. The most common preparation by the Miami people was to cut the squash in strips, allow it to dry naturally, and add desired amount to soups and stews. I would not recommend this preparation method for the humid climate of Florida.
Not only do these two stories of seed survival provoke an interest in gardening, they also bring up the question of the proper way to store and save seed. It is important that you choose to save seeds from open-pollinated varieties in order to save the traits of the parent plants. Most vegetable seeds can simply be washed, dried, and stored in a cool, dry space. However, the germination of tomato seeds can be increased by allowing them to ferment in water. For more detailed information on saving seeds, you may find this bulletin from The University of Maine helpful: Seed Saving for the Home Gardener.

We may be suffering from the recent low temperatures, but temperate fruit trees such as peaches and apples require a period of cold weather in order to become cold hardy and produce a good crop.
What is Cold Hardiness?
Cold hardiness is the ability of a plant to survive low temperatures. However, every cold event is fairly unique with variables such as when the low temperatures occur (early vs. late winter), how quickly the temperature drops, the temperatures in the days leading up to the event, and the length of time the low temperatures are sustained.
Cold Acclimation
Cold acclimation is the development of freezing tolerance in plants. Three fall environmental factors contribute to cold acclimation in fruit trees. Plant will develop 10 to 15 degrees of cold tolerance when the leaves sense shorter day lengths. Metabolic activity is increased when days are short and temperatures are between 60°F days and 40°F nights. The second factor occurs when lows reach the 20s, which can make trees up to 10 degrees hardier. The final factor occurs when temperatures dip to near zero, which fortunately for us does not occur very often.
Trees remain hardy during the winter as long as temperatures remain fairly stable. However, de-acclimation occurs in reaction to warm temperatures. This explains the winter flowering which occurred this past December. A cold snap may not injure trees unless it immediately follows a period of mild temperatures.
Florida Average Chill Hours Map – UF/IFAS Extension
Chilling Requirement
The cold weather and gradual cold acclimation are necessary to a tree’s accumulation of chill hours which is necessary for steady fruit yields. Chill hours are the accumulation of hours when temperatures are between 32°F and 45°F. The yearly average chill hour accumulation in Northwest Florida is between 660 and 700 hours. The apple varieties recommended for our area (‘Anna’, ‘Dorsett Golden’, and ‘TropicSweet’) have a chilling requirement of 250 to 300 hours. Some of the peach varieties recommended for our area (‘Flordacreast’, ‘Flordaking’, and ‘Gulfsnow’) have a chilling requirement of 350 to 400 hours. Please note the risk of planting these varieties because their chilling requirements are lower than our average chill hour accumulation. The varieties listed are for example, but other available varieties are suitable for our area.
Whether you like winter weather or not, just remember the satisfaction of eating fresh fruit in the summer. To track this year’s chill hours from the warmth of your home, please visit the AgroClimate tool at http://agroclimate.org/tools/Chill-Hours-Calculator/.

With the cotton harvest coming to an end, it’s not unusual to see cotton littered on the sides of the road. You may also think you see it hanging in the trees, but you will be pleasantly surprised to find a hidden gem. Woodbine (Clematis virginiana) and coastal virgin’s bower (Clematis catesbyana) are two native species of clematis that can be found wrapped around trees in the Panhandle. They have finished flowering for the year and you will notice their showy seed lint hanging in the trees.

Clematis leaves are compound, consisting of 3 to 5 leaflets, dark green and glossy with toothed edges. The vines are typically 1/2 inch in diameter and can grow to 20 feet. The flowers are much smaller than those of cultivated varieties found at garden centers. Flowers are white with prominent stamens. Clematis catesbyana and Clematis virginiana have similar flowers, but the flowers of C. virginiana are fragrant.
Clematis species grow well in partial shade to full shade. Native plants are often found entwined in the forest understory near streams or ponds where soil conditions are moist. Garden varieties grow well with their roots in moist, shaded soil and their leaves and flowers in the sun. They are often seen growing on a trellis or on a fence.

It is important to note that some species of clematis are invasive. Sweet autumn clematis or Japanese clematis (Clematis terniflora) is a vigorous invasive species that was once popular in southern gardens. This species has similar characteristics to C. catesbyana and C. virginiana, but its leaflets have smooth edges. You should develop a control strategy if Japanese clematis is found in your garden. For control options, please visit EDIS – Japanese Clematis.

Yaupon hollies (Ilex vomitoria) are evergreen, provide great fall/winter color, and can adapt to numerous landscape situations. They are also very durable and can survive extreme drought.
Characteristics
Yaupon hollies are dioecious, meaning male and female flowers are produced on separate plants and berries are only produced on female plants. Flowers are creamy white, but not showy on both male and female plants and berries can range in color from red to yellow depending on cultivar. The plants are favored by wildlife – pollinators are attracted to the flowers and birds love the berries.
Yaupon hollies are native plants with a number of different cultivars available at plant nurseries. ‘Jewel’ is a cultivar that produces an ubundance of red berries and ‘Aureo’ produces yellow berries. ‘Nana’, a dwarf, compact male cultivar is an excellent replacement for boxwoods. Large growing cultivars can grow to 15 to 25 feet tall and can be shaped as trees or left as large shrubs. ‘Folsom’s Weeping’ and ‘Pendula’ are two weeping cultivars that can be utilized as dramatic specimen trees.

Plant Care
Yaupon hollies prefer to be planted in full to partial sun. It is important to note that they are drought tolerant and require a site with well-drained soil. Because only the female plants produce berries, it is best to purchase plant material when plants contain berries in late fall and winter. Yaupon hollies spread readily by vegetative sprouts. Sprouts should be pruned down to the soil line 2 – 3 times per year. They do not have many disease or insect problems, but scale, leaf miners, mites, and aphids can sometimes be a problem.
Fun Facts
The leaves of the yaupon holly contain a higher caffeine content than any other plant native to North America. The Seminole Indians would purposely brew a concentrated “Black Drink” tea to induce vomiting and diarrhea for believed purification. Southerners utilized the caffeine in the leaves during the Civil War. If the leaves are steeped for a short period, a black tea or coffee substitute can brewed. A related species of holly (Ilex paraguariensis) from Brazil is used to make a drink called Yerba Mate, which is as popular in South America as coffee is in North America.

Next time 
you are in the grocery store, consider purchasing an extra jar or two of peanut butter and donating it to your local Extension office as part of the annual Peanut Butter Challenge. The Challenge is a food collection drive of peanut butter from within each of the 16 UF/IFAS Extension Northwest District Counties. UF/IFAS Extension Northwest District agents have been partnering with the Florida Peanut Producers Association since 2012 to collect peanut butter and distribute the bounty to local food pantries in each county. Annually, Ken Barton and the Florida Peanut Producers Association Board of Directors provide an additional two pallets of peanut butter (approximately 2800 jars) to be divided between the counties. Not only does the Peanut Butter Challenge help publicize the important contribution of north Florida’s peanut growers to the peanut industry, but it also helps provide a healthy and universally loved product, made from a locally grown product, to food pantries in northwest Florida communities from Pensacola to Monticello.
In 2014, Santa Rosa County collected 1477 jars resulting in more than a ton of peanut butter for their local food pantries. Escambia County was blessed by the support Helton Farms and Tri-County Peanut Buying Point. Rodney and Mike Helton and Tri-County purchased two additional pallets of peanut butter from Peanut Proud and helped to distribute to Escambia County Florida and Escambia and Baldwin counties in Alabama. In Washington County, the Public Library is doing a “Food for Fines” campaign, whereby patrons can bring in food in lieu of money for overdue fines. The library director is changing her campaign to require peanut butter donations as the food for fine forgiveness. They will collect peanut butter through November 30 and make a joint presentation with Extension to the local food bank.
As you can see, there are many different ways to get involved. Across the panhandle, 3463 jars of peanut butter were donated in 2014, amounting to almost 5000 pounds of peanut butter. We’d really like to surpass that number, so please consider helping us by donating as many jars of peanut butter as you can afford. The collection continues to November 25, 2015. Contact your local Extension office to find out where you can drop off peanut butter.
