Scientific name: rosmarinus officinalis
Rosemary is a woody evergreen herb that grows into a shrub up to about a metre and a half tall and much wider again. It can be clipped into a hedge or other topiary shapes. It has very strong smelling narrow leaves and purple flowers. It grows well in hot, dry conditions and most varieties tolerate heavy frosts. It does not like being overwatered. Rosemary goes very well with lamb dishes, but can be used to flavor a variety of other foods too.
