When it comes to identifying a juniper tree, one of the most helpful characteristics to look out for are its cones. The cones of juniper trees can provide valuable clues in determining whether a tree belongs to the juniper family or not.
First, it’s important to note that juniper trees are dioecious, meaning they have separate male and female plants. This distinction becomes particularly relevant when examining the cones.
On male juniper trees, the cones are small and typically range in color from yellow to tan. These cones are often inconspicuous, as their primary purpose is to produce pollen for fertilization. So, if you come across a tree with small, yellowish or tan cones, it’s likely a male juniper.
In contrast, female juniper trees produce berries, which are actually modified cones. These berries are often more noticeable and can add a splash of color to the tree. The berries go through a transformation during their development, changing in color as they mature.
In the case of Northwest species of junipers, the berries start off green but eventually turn blue at maturity. This blue coloration is a key characteristic of many juniper species found in the region. However, it’s worth noting that not all juniper species produce blue berries. Some species, such as the Utah juniper, have red berries instead.
To summarize, when trying to identify a juniper tree, pay close attention to its cones. Male junipers have small, yellow or tan cones, while female junipers produce berries that can range in color from blue to red, depending on the species. By observing these distinct cone characteristics, you can become more adept at identifying juniper trees in your gardening or landscaping endeavors.
