Welch Juniper Thrives in Dry, Sunny Sites

Think of the Welch juniper as a good-looking Westerner, new in town, with the power to soothe your worries and solve your troubles. This slender, upright evergreen is a cultivar of Rocky Mountain juniper, and it thrives in dry, sunny spots where other plants simply bake.

Welch juniper (‘Welchii’) is reminiscent of the columnar ‘Skyrocket’. Both are cultivars of the Rocky Mountain juniper (Juniperus scopulorum), but the Welch juniper has softer foliage and a slightly wider habit. Its silvery-green foliage can take on a blue hue, especially in winter, and it carries small blue-gray berries that take two to three years to mature.
