A sterile hybrid of sweet marjoram and oregano grown in gardens as a culinary herb; its small white flowers, blooming for a long time in summer, give bees nectar.
Hardy marjoram is a natural or garden hybrid between sweet marjoram (Origanum majorana) and a subspecies of wild oregano (Origanum vulgare). It does not set seed and is propagated by cuttings or division. It is preferred in herb gardens because it is more cold-hardy than sweet marjoram. Its small white flowers open in dense spikelets and, like other oreganos, offer bees nectar.
It flowers for a long time, from July to September. If the flowering shoots are not cut for harvest, it becomes an uninterrupted bee source in the garden for mid and late summer.
Because the areas where it is grown are small, its honey contribution is negligible. As a sterile hybrid, its pollen production can be expected to be weak; no measurements specific to this plant were found.
In gardens around the apiary, harvesting the leaves for seasoning before flowering and leaving part of the plant to flower benefits bees. Its naming in Turkey is confused; it should not be mixed up with sweet marjoram or with İzmir oregano.
