Conradina verticillata Cumberland Rosemary is a rare, low-growing evergreen shrub in the mint family, native to the Cumberland Plateau of Tennessee and Kentucky. Considered endangered, this special plant was carefully selected from the wild by Steve Breyer of Tripple Brook Nursery (South Hampton, MA) and shared for propagation, ensuring its continued presence in landscapes. This compact variety gradually spreads 6–8 inches per season, reaching about 4 inches in height. Its slender, needle-like leaves are evergreen, fragrant, and reminiscent of culinary rosemary—making them a useful substitute in the kitchen. Branches can also be dried for long-lasting fragrance, and the rosemary-like scent is known to help repel insects. In late spring to early summer (May–June), every stem is crowned with delicate lavender flowers, offering a charming display of soft color. Cumberland Rosemary thrives in partial shade to full sun and is well-suited to sandy or gravelly soils. Remarkably versatile, it is drought-tolerant yet also content in moist conditions. Hardy in zones 5–8.

Growing Tips & Guides

Get Started

Initial Instructions
Upon receiving and carefully unpacking, water as needed and allow the plant a few days to gradually acclimate to full sun before planting out. Prepare a hole enriched with compost or other organic matter.

Cultivation
Native to North America, this evergreen shrub is drought tolerant, making it ideal for hot, dry climates. Water deeply once or twice a week, ensuring the soil and root zone are thoroughly moistened. During dry periods, additional watering may be needed to maintain consistent soil moisture.

Size at Maturity
4-8 inches tall x 18-24 inches wide

Spacing
12-24 inches

Pests & Diseases
The plant is generally hardy, but poor drainage, overwatering, and high humidity can increase its vulnerability. To control aphids and spider mites, use a three-step approach:

1) knock pests off with water
2) spray leaves with insecticidal soap or horticultural oil, focusing on undersides and leaf axils, and
3) repeat within 5–7 days to control newly hatched insects.

If rosemary beetles appear in late summer, handpick, shake off, or vacuum them. Common diseases include powdery mildew, which can be treated with neem oil or a baking soda solution, and root rot, which may occur if the plant does not receive enough sun or sharp enough drainage.

Hardiness
USDA Zones: 5-8.

Bloom Time
Late spring to early summer (May–June).
