Rocky Mountain White Heather

Cassiope tetragona subsp. saximontana

Rocky Mountain White Heather is a low-growing perennial shrub that is native to the subalpine elevations of North America's Rocky Mountains. It thrives in damp, well-drained soil and full sun, and grows to a height of 4–5 inches with a spreading habit of 8–12 inches. Its evergreen leaves are L-shaped, small, and leathery, and clusters of pinkish-white, bell-shaped blooms appear in Summer and Autumn. Its dense mat-like foliage and masses of blooms make it an attractive addition to garden beds, pathways, and rock walls. Plus, this hardy plant is low-maintenance and deer-resistant, making it perfect for gardeners of all experience levels.

watering

Clubmoss Mountain Heather should be watered regularly and evenly throughout the summer growing season, which typically begins once the plant begins to actively grow in the spring or early summer. Water the plant deeply to saturate the soil around the roots. Watering in the early morning is ideal to give the plant time to dry out before evening temperatures cool. During particularly hot and dry periods, water the plant more frequently. Avoid wetting the foliage, as this can encourage fungal diseases. In the winter, reduce watering frequency, as the plant is dormant and does not grow or need moisture during this time.

sunlight

Clubmoss Mountain Heather needs at least 4 hours of direct sunlight per day for optimal growth. This plants prefers partial to full sun and grows best in bright, indirect sunlight like that found in the shade of a tree or under a shady porch. It's best to provide the plant with morning sun and afternoon shade or vice versa, as the direct afternoon sun can scorch its leaves. When grown indoors, place the plant near a south-facing window for the best light. Make sure the light is bright, but not direct, as bright light indoors can still be too intense for the plant.

pruning

Clubmoss Mountain Heather (Cassiope lycopodioides) should be pruned in late winter or early spring just before new growth begins. The amount of pruning will depend on the desired size and shape of the plant. Light pruning is recommended for this species, primarily removing dead or damaged branches. Remove no more than 1-third of the shoots at any 1 time and don't prune below the point where needles are growing.
