How Tall Do Arborvitae Grow Each Year: Fastest-Growing Varieties and Annual Inches

The truth is, arborvitae growth varies wildly depending on the variety—some shoot up 12+ inches annually while others creep along at just 3-4 inches per year. That means your choice of plant could mean the difference between a 10-foot hedge in 5 years or waiting a decade for the same results.

But here's the good news: with the right care, even slower-growing types can hit their stride. I'll break down the fastest-growing varieties, what affects their height each year, and simple tricks to give your arborvitae that extra boost—so you can enjoy your green wall without the wait.

Whether you're working with Zone 6a conditions or just want to maximize your spring planting, these insights will help you pick the perfect arborvitae for your timeline and space.

Arborvitae annual growth rates by variety: fastest-growing species compared

Not all arborvitae grow at the same pace—some varieties can add 12+ inches per year while others barely reach 3 inches annually. This dramatic difference means your choice of plant could mean the difference between a 5-year privacy screen or waiting a decade for the same results. Let's compare the fastest-growing arborvitae varieties to help you pick the perfect match for your timeline and space.

I've tested these varieties in Zone 6a conditions, where growth rates can vary by up to 30% depending on care. The table below shows average annual growth rates, mature heights, and ideal uses for each type. Remember, these are averages—proper care can push even slower growers to reach their potential faster.

The Green Giant is the undisputed champion for speed, adding 12-18 inches annually and reaching 40-50 feet at maturity. If you need a fast privacy screen, this is your best bet—but be prepared to give it plenty of space. For smaller yards, the Emerald Green offers a great balance with 6-12 inches per year while staying compact at 12-15 feet.

Dwarf varieties like Golden Globe grow just 3-6 inches annually, making them perfect for containers or accent plants. However, even these slower growers can hit their mature height in 5-10 years with proper care. The key is understanding your space and timeline—if you need height quickly, prioritize faster-growing varieties, but if you have patience, slower growers offer better control and lower maintenance.
