Greek Oregano 'hirtum'
Often considered the true "pizza herb," Origanum vulgare subsp. hirtum (sometimes listed as 'hirtum') is the most flavourful and pungent of the oreganos. It is a hardy, woody-based perennial that forms a low, spreading mound of small, hairy, dark green leaves. In the UK, it is highly valued for its intense, spicy aroma and taste, which is much stronger than the common wild marjoram. It produces clusters of white flowers in late summer, which are highly attractive to pollinators. To thrive in the British climate, it requires a very sunny spot and excellent drainage; it is particularly susceptible to "wet feet" during the winter. It is an ideal plant for gravel gardens, south-facing banks, or containers where the soil can be kept lean and dry. Regular trimming prevents the plant from becoming leggy and encourages a constant supply of the aromatic leaves that can be used fresh or dried for year-round culinary use.
