Planet Earth^™ Arborvitae has a perfectly rounded, dense habit without any shearing. It thrives in warm climates, does equally well in cold climates, and is resistant to Passalora/Cercospora needle blight. The green foliage takes on bronze tones in colder climates. The perfect round shape and compact habit of Planet Earth^™ creates an excellent informal hedge, foundation planting, or mixed border.
