The leaves of this tree are sharp enough they hurt!
No big surprise, but Giant Sequoias are only native to California. This species of the Cupressaceae family is the only member of its genus Sequoiadendron. The trees are also called big tree and Sierra Redwood. They are so large, they often have monikers. The largest standing today is the General Sherman which has a volume of 52,500 cubic feet and is over 274 feet tall. Due to their height and trunk volume, these trees are often referred to as the largest living things on earth. General Sherman is not the tallest known Giant Sequoia. The tallest is said to be over 300 feet and grows in a known grove but the exact tree is not specified. Sequoias may also be some of the most long-lived, as the oldest one by stump count in 1870 was 3266 years.
As this tree grows fast even in old age, it is possible the General Sherman will get both taller and wider! Although Giant Sequoias would provide a lot of wood per tree, most of them are protected. Once used for fenceposts, their wood is rot resistant but also brittle, making it less than ideal for building. The local Native Americans, members of the Tule River Tribe, did use the wood for fenceposts and crafts, but instead of felling the trees, they utilized downed wood. After the white man discovered the Sequoia, many were lumbered, eventually leading the preserved groves to be added to the National Park System.
North American Trees (Preston and Braham, 2002) mention that a “dark red pigment in ink” can be obtained from the cones. One advantage of having a smaller tree in the park is you can feel the leaves, which I think are the prickliest of the conifers. They hurt!
Sequoias have been planted elsewhere in the world, including Denmark and France. In the mid 1800s, Giant Sequoias were a popular addition to English castle gardens, where conditions appear to be ideal. Some of the largest specimens in Europe can be found in Great Britain. In the relatively few tree-years since then, some specimens have acquired height of around half the tallest in the US. Another group of trees which were planted in Denmark to help with reforestation, where killed in the winter of 1942. Today many visitors from around the world take home seeds to grow the trees.
To find B116 Giant Sequoia (Sequoiadendron giganteum) go to the triangle formed at Oak, Jackson, and City Park. In this area is a stone bench. If you were to sit on the bench facing south you would be looking toward the Giant Sequoia, which is parallel to the lamp post.

Juniperus is the largest of the genus in family Cupressaceae and consists of at least 55 species. Four species are mapped in City Park. Four species are also native to Colorado, three of which are marked in the park. The fourth, Juniperus communis is a low-spreading shrub. (Flora of Colorado, Ackerfield, 2015.)
The junipers, often mistakenly called cedars, were used by many Native American tribes. Rocky Mountain Juniper branches were used for purification, the red colored wood for lance shafts and bows. The Cheyenne were said to prize the wood for flutes. The boughs were used to line sweat lodges, and a few tribes bathed their horses in water steeped with juniper to give their coats a high sheen. It may also have been a dandruff deterrent.
The berries, which are actually the seed cones of the plant, could be dried and strung for necklaces. An ingenious way of producing a hole in the berry was to allow ants to eat out the sweet inner core. Smoked they turned black. Dyes can be made from the roots and berries. One source mentions that the wood is used in making pencils.
Mythology says that juniper boughs have been used to ward off devils and witches, while dreaming of the berries had symbolic meaning. Giving berries as gifts conferred honor on the recipient.
Of course, there were numerous uses of the berries as both food and medicine, but not only in Native American cuisine. In Europe they are used to flavor German sauerkraut and Swedish pickles, as well as to cut the gaminess of venison and other meats. One of the best known uses for juniper berries is in making gin. Edible & Medicinal Plants of the Rockies (Kershaw, 2000) includes an easy recipe for making a Tricky Mary, a virgin Bloody Mary in which you allow juniper berries to flavor tomato juice.
Medicinal uses include the ubiquitous cure for a cold and other chest aliments, as a digestive aid, and for inflammation. According to Edible & Medicianal Plants of the Rockies a berry tea has been used to prevent pregnancy and also as a hunger suppressant. The berries were used by practitioners in the Middle Ages to help ward off Black Death.
At the same time that many books and sites on the Internet provide recipe ideas for the berries, most also warn against large doses, especially for pregnant women. Edible and Medicinal Plants of the Rockies warns that over ingesting can result in convulsions and kidney failure while oil applied topically may case blistering. Even those who tout natural remedies warn against eating the berries without knowing what you are doing. At least one species is identified as a known toxin.
Rocky Mountain Juniper(Juniperus scopulorum) is native throughout Colorado other than the most eastern counties. Trees can grow even in Weld and Logan counties. Rocky Mountain Juniper grow through most western states except California. One clue to its habitat range may be that it does not tolerate high humidity. This species was used in ways similar to the general discussion above.
The twigs and branches of Juniperus scopulorum are an important food source for the elk and deer of the region, while the berries are an important part of the diet of many smaller males and bird.
The One-Seed Juniper is native to the American Southwest. Its range includes southwest Colorado (Flora of Colorado, Ackerfield, 2015). Its name is derived from the fact that its cones (berries) normally have but one seed each. The plant is common in the higher elevations of New Mexico and due to its long tap root, is able to survive in drier areas. The Santa Fe Botanic Gardens Newslettersays the ash from this tree is still used in Navajo wool dyeing as well as part of traditional Pueblo food recipes. The branches and smoke from burning juniper are also part of various ceremonies. Other sources mention that the bark was used to make mats and cloth.
The Utah Juniper grows naturally in nine of the western states, including Colorado. Again, it is not native to Larimer County. Canyonlands National Parks says this “indomitable Juniper” can grow in “an environment of baking heat, bone-chilling cold, intense sunlight, little water and fierce winds.”
The Alpine Nature Center in Alpine, Utah, provides a chart of the differences between the Rocky Mountain Juniper and the Utah Juniper.
Most of the distinguishing characteristics are related to color and shape. For instance, the bark of the Rocky Mountain juniper has a reddish hue while that of the Utah is more gray. This is barely discernible in the photos accompanying this post. The biggest difference might be that both male and female cones are born on the Utah Juniper while the Rocky Mountain junipers have distinct male and female trees. The aforementioned site claims a yeast in the berries is what is important to the gin making process. It also includes a recipe using juniper berries as the starter for a sourdough!
I’ve been aware of a literary journal called Alligator Juniperfor some time and always thought it was an odd name until I learned it was named after the Alligator Juniper tree.
Its habitat in the US includes only Arizona, New Mexico, and Texas. One look at its bark, and it is easy to understand where it got its name.
This species has both male and female trees, with only the berries/cones on the female tree worth eating. The male pollen cones are the reason this tree is listed as a moderate allergen.
According to a post about the trees in Texas, this is a slow grower. One interesting study of the effects of climate change has shown that the Alligator Juniper has “crept” to higher elevations over the last fifty years.
The mentioned uses of the berries and other parts of the tree coincide with those of other junipers, although some reports for this specific species mention how strong the juniper taste is. For those of you interested in boutique spirits, at least one company is making a gin with Alligator Juniper berries known as Mt. Lemmon Gin. The Zuni use it as incense.
How to find the Junipers:
E60: Rocky Mountain Juniper (Juniperus scopulorum) Find the tagged specimen on the other side of the fence in front of the miniature train station. It is across from Club Tico on City Park Drive.
D199 One-seed Juniper (Juniperus monosperma). This tree is located along the east side of Sheldon Lake between the lake and the road, near the Douglas Fir and the frog statues. One author mentioned that One-seed Junipers look somewhat like Arborvitae, so look for a squat conifer.
C127 Utah Juniper (Juniperus osteosperma). This specimen is located between playing fields on the S side of City Park Drive as you head toward the Jackson Street exit. If you are driving east from the junipers mentioned above, cross Sheldon Drive and park about two-thirds of the way to the exit, near a group of trees that are encircled with bricks. You will need to walk as the tree is a short distance from the road. I was not able to locate the tag, but after reading that the Utah juniper produces both seed cones (berries) and pollen cones, it seemed obvious that this is the correct tree.
To find C157, Alligator Juniper (Juniperus deppeana), you could walk south from the Utah Juniper toward the corner of W. Mulberry and Jackson to a small clump of trees. You could also drive and park just S of the intersection of W. Magnolia and Jackson. This smaller conifer seems set off by itself. To find the tag, you need to walk into the branches.
