When we get right down to it, gardens are about green – lush, rich green. Whether it’s our lawns or our trees, green is the backbone of every garden and this restful, yet vibrant color is what we look for, and expect to see. Yes, there is plenty of room for wonderful bright foliage colors, from yellow to purple and red, but they too look best set against a rich green backdrop. When it comes to low-maintenance evergreen shrubs, the Hot Head® Arborvitae stands out as the coolest green around. After all, it was produced in a breeding program designed to find a super-green arborvitae, and it worked.

The Hot Head Arborvitae is very cold-hardy, compact evergreen, growing into a rounded ball, a little taller than it is wide. It grows at a moderate pace, so that in 10 years it will be about 3 feet tall and 2 feet across, with a dense, compact branching structure that needs no trimming to always look perfect. The rich green leaves are tiny, and cling to the branches, forming fan-shaped branchlets that live for several years. Those leaves and branchlets are the richest green possible, and they stay that way every day of the year, even when the temperatures plummet.

Growing Hot Head Arborvitae Trees

The Hot Head Arborvitae is perfect to use around your home as an important part of the foundation planting. Low enough to fit beneath windows, and round enough to fill the spaces, it can be planted alone, or in groups of 3, 5 or more, adding valuable structure to your planting arrangements. Use it too in the foreground of your shrub beds, to anchor both the shapes and colors of other shrubs. It can be grown in a row as an interesting edging to border a path, driveway or fence, or as a low hedge between one part of your garden and another. In warmer zones it also makes a terrific container or planter shrub, filling pots all by itself, or with other plants around it, and making a bold formal statement on either side or a door, or flanking stairs or an entrance way. Wherever you need a bold, green accent, this is the bush you need.

The Hot Head Arborvitae is an amazingly tough plant. It was bred in Georgia, so we know it grows well in zone 8, and this species is already well known for growing easily in zones 3, and even in zone 2. That means it will grow just about anywhere in the country with ease. In outdoor containers it can be planted in zone 5 and warmer zones. Plant it in full sun or partial shade. It grows well in ordinary garden soil, doing best in moister but well-drained soils, but surviving normal periods of drought well once it is established. It will not grow so well in saturated ground, or in hot, dry, sandy places where it doesn’t have regular water. It almost never suffers from pests or diseases. It certainly doesn’t need trimming to keep it neat and compact – it does that naturally – but in too much shade the foliage will be more open, and you may need to trim it a little to keep it neat. You can of course also trim to keep it as a perfect globe, or to control its height in future years. All dwarf evergreens grow throughout their life, and the Hot Head Arborvitae adds about 2 inches to its height every year, so it will in time become significantly taller.

History and Origins of Hot Head Arborvitae Trees

The Hot Head Arborvitae is a selected plant of the American arborvitae, or white cedar, Thuja occidentalis. This plant grows naturally through all the colder north-eastern states, and up in south-eastern Canada too. It is found wild as a medium-sized tree, between 40 and 60 feet tall when mature, and it lives for centuries. It grows on the edges of forests, around wetlands, and on rocky cliffs and outcrops. It is called ‘arborvitae’, which means ‘tree of life’ because early French explorers discovered that native Americans used a tea made from it as a winter supplement to prevent and cure scurvy. It contains more Vitamin C than orange juice, as well as essential amino acids needed for good health in the hard times of living off the land through a northern winter. It was the very first North American tree to be grown in Europe, at the Jardin du Roi (garden of the King), in 1540.

The Hot Head Arborvitae is the product of a project by Professor John M. Ruter, a plant breeder specializing in ornamental plants at the Institute of Plant Breeding, University of Georgia, Athens GA. He took seed from plants of the Holmstrup Arborvitae, a columnar variety already known for its rich-green color throughout the year. From an original 35 seedlings he selected 5 for further trials, and then, after years of testing, he selected the most compact and richest-green of them all. It was patented with the official name of ‘RutThu#1’ in 2016, and this brand-new, breakthrough plant is sold with a registered trade name as the Hot Head® Arborvitae.
