The Wild Harvest Digest: December 2025, #3

Good Morning Neighbors,

As promised, today we’re going to talk about a plant that is deeply entwined in our American holiday traditions. #Holly
<Alt Text 1 of 3> Today we’re talking about the Hollies; no not the band, the perennial plant. The holly family which is collectively known as Ilex, have members of its immense family on pretty much every landmass except for Antarctica because, well it’s cold as heck down there. In our region you can get a Holly in a surprising number of shapes and forms but generally you will seed just a hand full on repeat in the urban landscape. Typically you will see Yaupon Holly (Ilex vomitorium), ‘Sky Pencil’ Holly (I. crenata), Chinese Holly (I. cornuta), Gallberry (I. glabra), American Holly (I. opaca) and, Winterberry (I. verticillata) in our Carolina landscape but there are many more options. Also I do need to mention that the herbal ingredient Yerba Mate (I. paraguariensis) is also a Holly. While we’re on that the Americas have several other native Caffeine-bearing Holly relatives as Yaupon Holly and, Guayusa (I. guayusa) with the latter being hardy in North Carolina so we do have a caffeine alternative to Coffee if needed. The specific member of the family we are here to talk about is Chinese Holly (I. cornuta) which is abundant in the landscape and can be found in incredibly prickly forms like ‘Rotunda’ or ‘Needlepoint’ which are viciously unapproachable but excellent habitat for wild birds who often make nests in the bushes. The variety in the included photographs are a less painful type called ‘Carissa’ which are a dwarf or semi-dwarf variety that was named for its foliage’s resemblance to the Natal Plum’s foliage. What makes these perennial, evergreen plants great in the landscape is that with age they will form a nearly impenetrable barrier. In the case of ‘Carissa’ though their slow growth and a normal upper height of about four feet is great for making a natural fence. <Alt Text 1 of 3> <Alt Text 2 of 3> Carissa also shears well into shapes and is very tolerant of abuse however since it is a slow grower drastically heavy pruning will leave it looking bad for a long while. As a weird note here, Hollies are considered a hardwood plant, and a mature Holly trunk can absolutely wreck a car. So as a “soft” vehicle barrier mature Hollies are an effective way to guarantee that if you have problems with bad drivers they might not have a vehicle to cause mayhem with. As an environmental note here, Chinese Holly does produce red berries that are attractive to wild birds, and its flowers attract all sorts of Native Bees and Solitary Wasps. Chinese Holly foliage is very resistant to damage by Deer and dense hedges of hit may act as a deterrent to deer. It is also important to mention that Chinese Hollies are resistant to Phytophthora Root Rot. Garden considerations aside, Hollies are a common theme in Christmas decoration; if you go to arts and craft stores you will see the plastic garlands with imitations of their leaves and their berries. In various paper decorations you will see that they are represented there too as well as Wreaths, and sometimes they are incorporated in gift wrapping. Hollies have an interesting history in regards to the holidays, according to an article written by Dixie Sandborn at Michigan State University the use of Hollies in holiday ritual as we know it may have started in Northern Europe with the Pagans. The Druids wore it as ceremonial head wear when they went into the forest, The Romans used as an offering to the god Saturn during the festival of Saturnalia. The Romans placed such a high value on the plant that it appears in most if not all images of Saturn. Christians placed it in decorations that adorned doorways as a method of preventing persecution. It was thought that hanging holly on the door of one’s home would prevent the entry and attack of supernatural specters that attacked during the holy days. <Alt Text 2 of 3> <Alt Text 3 of 3> Other sources indicate that Christians further adapted the meaning of holly, and its symbolism became something more direct. The Holly’s red berries came to represent the blood that Jesus shed on the Cross, while the pointed leaves represented the crown of thorns placed upon Jesus’s head. It is fairly well documented that in ancient European traditions specifically Celtic and Druidic, Holly was considered a masculine plant with characters such as the ‘Holly King’ representing the power of winter. Humorously they did not know that a lot of species of Holly are dioecious meaning the plants are male and female. So, we now know that their Holly King might have been a Holly Queen. In contrast though Ivy (Hedera helix), was considered Feminine, which is also pretty funny because English Ivy is hermaphroditic. Also English Ivy takes decades to reach a state of maturity changing into a plant that barely resembles the plant we thought we knew. From these two plants, and their use in Celtic/Druid ritual eventually a Christmas carol was created called “The Holly and the Ivy” in the 18th century and formally recorded by Cecil Sharp in 1909. But as always, the Holiday traditions you hold are based on what you’ve been taught by friends and family and what you determine is acceptable in your home with those you care about. Hollies are one of those plants that have become significant over the ages to mankind and every so often they manage to surprise us. Before I end this article I’ll leave you with one interesting fact about a local species of holly you probably never think about. Remember the Carolina Blue Honey? The color in part or whole comes from Gallberries (I. glabra) which are native to our region and typically found in the forests. It is thought that Honey bees go after the juices of the berries which transfer their color to the honey making it blue. Thank you all for reading and please have a happy and safe Holiday. <Alt Text 3 of 3>

It is a product of the human metabolism of caffeine, which is metabolised in the liver into 12% theobromine...

...and it is found in chocolate and several other foods, including tea (Camellia sinensis), some American hollies (yaupon and guayusa) and the kola nut.

Actually strictly speaking its just yerba mate (ilex paraguariensis), guayusa (ilex guayusa), and yaupon/cassena (ilex vomitoria and ilex cassine) that are caffeinated. Plenty of other edible holly but those are the only 4 caffeinated ones.

normalmente se toma infusión, tiene un sabor parecido al mate, de hecho son del mismo género:

Gran apunte. Es fascinante ver cómo ingredientes como la guayusa ganan popularidad. Para el día a día, el reto es tener la claridad para entender qué los hace especiales: ¿son los antioxidantes? ¿la cafeína? Saber el "porqué" es lo que te da el poder de decidir si es para ti o no.

Did you know guayusa tea is a great coffee substitute? 🍵
Beyond caffeine, it's packed with health-promoting compounds! Used for centuries by Amazonian people, it was valued for digestion, energy, and even in some rituals.

Looking for a coffee substitute?

Guayusa is great ('rocket fuel' a friend says) & often grown by Indigenous/local communities & coops via #agroecology #agroforestry, supporting #biodiversity & #climate too

I mail order it but was glad to finally meet this generous tree while traveling in Ecuador:
