Description

Rosemary is a hardy evergreen shrub in areas where winter temperatures stay above 5°F. In the Northeast, however, this perennial should be taken indoors or moved to a protected location and kept as a container plant during winter. The narrow leaves have a leather-like feel and a spicy, resinous fragrance.

Culture

Rosemary grows best in well-drained soil with a pH between 6.5 – 7.0. Prefers full sun. It can be propagated by cuttings or grown from seed (can be slow to germinate). Pinch seedlings and young plants to direct growth. Grows to a height of between 36-72”.

Harvesting

Cut fresh leaves as needed. Can be dried. 

Use

Rosemary is a popular flavoring for meats, vegetables and dressings or as a garnish on roasts. Oil from leaves is used in medicine.
