Rocky Knoll Farm Calluna vulgaris Caleb Threlkeld Heather

This variety has a prostrate, mat-forming habit, meaning it stays very low to the ground. It reaches a mature height of only about 6 inches and spreads to roughly 1.5 feet, making it an excellent choice for groundcover or edging.

Yes, like most heathers, 'Caleb Threlkeld' prefers well-draining, acidic soil. If your garden soil is heavy clay or alkaline, you may need to amend it or consider planting in containers to ensure the plant stays healthy.

Yes, this variety is known for being deer-resistant. While no plant is entirely immune to hungry wildlife, deer generally avoid this heather, making it a safer choice for landscapes in areas with high deer pressure.

It is perfectly suited for containers. Its compact, low-growing nature makes it ideal for pots, window boxes, or mixed arrangements where you want year-round evergreen foliage and seasonal color.

It is relatively low-maintenance. It requires full sun and moderate watering, especially until established. Because it is an evergreen, you get year-round color without needing to prune it back significantly, though a light trim after flowering can help maintain its shape.

This variety is hardy in USDA zones 4 through 9. It is well-suited for cooler climates and is quite resilient, provided it has the necessary drainage and sunlight.
