What is being compared
Why these get confused
Oregano, marjoram and Mexican oregano are three names covering plants from two families, and the taxonomic authority calls the main one wild marjoram.
Point by point
| Aspect | Oregano | Thyme |
|---|---|---|
| The naming problem | GRIN’s only English common name for Origanum vulgare is 'wild marjoram' — not oregano. | Straightforward: thyme, common thyme, English thyme, garden thyme. |
| Native range | Enormous — north Africa, all Europe, western and central Asia, China, India. | The western Mediterranean only. |
| Flavour | Peppery and warm with a resinous depth and firm bitterness. | Sharper and more medicinal-smelling. |
| Drying | Concentrates the aroma; dried is preferred to fresh. | Holds up well, losing the fresh green top note. |
| What else carries the name | Mexican oregano is a Lippia — a different family entirely. | Little confusion beyond cultivars. |
| Wild versus cultivated | Wild Greek rigani is markedly stronger than cultivated. | Same pattern, and easy to smell in the packet. |
The short answer
Oregano is the rounder in a cup and thyme the sharper. With oregano, check which plant you have: the word covers two families.
