A clump-forming, shrubby perennial, Origanum majorana is a slightly fragrant herb that adds a sweeter taste to food and drink. It’s evergreen only in frost-free areas due to its dislike of cold. Small, and mid-green, it grows low but upright, with its woody branches thick with small, ovate leaves. In summer, its tiny green bracts produce thick trusses of bi-lipped lavender and white flowers. It is these knotty bracts that inspire its common name, the Knotted Marjoram. A lover of well-drained, loamy or sandy soil, it thrives in full sun locations. As a cold-sensitive plant, it’s best to grow indoors under glass if the climate is harsh. Pruning by deadheading helps curtail its vigorous spread.
