This lovely yellow-leaf form of the culinary Origanum vulgare was named after oregano expert, Dr. J.H. Ietswaart. Origanum vulgare 'Dr. Ietswaart' makes a 6" tall x 3' wide patch (5 years) of round, golden yellow leaves with a delicious mild fragrance. In midsummer, the clumps are topped with 1' tall spikes of very pale lavender flowers...outstanding in both the garden and the kitchen.
