Arborvitae

 An **arborvitae** (botanical name *Thuja*) is a very popular type of evergreen coniferous tree or shrub belonging to the cypress family. The name itself comes from French, meaning **"tree of life,"** a nod to its historical medicinal uses and its tough, long-lived nature.

They are staples in backyard landscaping across North America. Here is a quick breakdown of what makes them unique and why people use them:

### Key Characteristics

 * **The Foliage:** Unlike pines or spruces that have sharp, pointy needles, arborvitae have flat, scale-like needles arranged in soft, fan-like clusters. They are soft to the touch and give off a clean, pleasant citrusy scent if you crush them in your hand.

 * **Growth Habit:** They typically grow in a very distinct, neat pyramidal or columnar shape. Because they naturally grow tall and narrow, they take up very little ground footprint while reaching high into the air.

 * **Year-Round Green:** They retain their dense green color all through the winter, providing reliable color when everything else is bare.

### What They Are Used For

Because of how they grow, they are the absolute go-to choice for specific landscaping jobs:

 * **Living Privacy Screens:** Homeowners plant them in dense rows along property lines to block out neighbors, roads, or unsightly views.

 * **Windbreaks:** Planted tightly together, their dense foliage does an excellent job of cutting down strong, chilly winds.

 * **Low-Maintenance Backdrops:** They make great, clean green backdrops for flower beds, patios, or corners of a house.

### Popular Varieties

They come in many shapes and sizes, ranging from tiny round bushes to giants:

| Variety | Growth Shape | Mature Height | Common Use |

|---|---|---|---|

| **Emerald Green** | Very narrow, tight column | 10–15 feet | Small yards, tight property lines, formal hedges |

| **Green Giant** | Broad, massive pyramid | 40–60 feet | Large properties, massive windbreaks, fast privacy |

| **Globe / Tater Tot** | Round, compact ball | 2–5 feet | Garden accents, foundation planting, walkway borders |

### One Crucial Pruning "Quirk"

The most important thing to know about caring for an arborvitae is that **it only grows new foliage from its outer green tips**.

Inside the tree, where the sun doesn't reach, there is a "dead zone" of bare wood and old brown needles. If you hack into that inner brown wood, the tree cannot sprout new growth there, and it will leave a permanent, ugly bare spot. Because of this, they can only be lightly sheared on the outside to keep their shape, rather than heavily cut back.
