Plant Oregano And Marjoram For Bees
Bees love oregano and marjoram (Oreganums), this group of fragrant herbs are irresistible for bees.
At a visit to a beautiful historic garden recently, it was interesting to observe which flowers the bees and butterflies were mostly foraging upon.
Of course, whether or not a plant is being visited by pollinators has much to do with the stage of the flower (whether it is in the phase of offering maximum reward in terns of nectar and pollen) – and this in turn can be affected by other variables such as the time of day, location of the sun, and the plant’s health.
It also depends on the types of bees and other pollinator species abundant locally, and the other flower types in the vicinity.

Which varieties of oregano and marjoram are most attractive for bees?

A further species known to be especially popular with bees is Origanum syriacum, (common name, 'Lebanese Oregano' or 'bible hyssop'), although I have no experience of this particular plant.
Which bees visit Oreganos and Marjoram?
Bumble bees foraging on a small patch of Oregano (Marjoram)One study in Jordan involving 16 small shrubs observed as many as 21 different species of bee visiting Origanum syriacum flowers1 over a period of 42 consecutive days.
Other insect visitors, mostly hymenopterans, were also recorded.
Bees from 4 different families were observed (Apidae, Megachilidae, Andrenidae and Halictidae. Of those that could be identified by the authors of the study, come of the visiting bee species recorded were:
Apidae:
Eucera nigrescens
Nomada succincta
Apis mellifera
Tetralonia salicariae
Tetralonia dentata
Megachilidae:
Anthidium undulatum
Anthidium dentatum
Heriades syriaca
Heriades truncorum
Andrenidae:
Andrena flavipes
Andrena nitida
Halictidae:
Halictus aegypticola
Halictus sexcinctus
Halictus quadricinctus
Lasioglossum calceatum
Lasioglossum lineare
Lasioglossum pauxillum
Why do bees like oregano and marjoram? Why do so many bees visit the flowers?
There are two main reasons.
- They provide lots of nectar.
- Oregano and marjoram are generally in flower during the height of summer, when colonies are fully in development, meaning there are more hungry bees to feed: mature bees feeding themselves and also foraging to take food back to the young at the nest or hive.
Therefore, bees will be more visible around these plants because it not only offers plenty of reward in the form of nectar, but also because bee populations are at their peak when oregano is at its most attractive to bees.
How to plant oregano /marjoram for bees, butterflies and other pollinators
Plant oregano in a sunny spot. One of the great things about oregano is that it is fairly tolerant of poor quality, dry soils. It can tolerate a certain amount of drought.
You can sow oregano from seed, take cuttings or potentially divide plants in autumn to increase the size of your patch. I like to offer at least 2 patches of popular bee-friendly plants at different locations in the garden, if I can.
Cut back old flower stems in autumn.
How to divide oregano plants
To divide the plant:
- First cut back old flower stems.
- Prepare a place for the new plants to go – remove weeds, dig a space and water well.
- Dig up the whole of the oregano plant, and use couple of forks to divide the plant in two down the centre.
- Replant the sections of plant, ensuring the roots are well covered and the plant is firmly in the soil.
- Once you divide the plant, it may ‘sulk’ for a while, but should eventually recover.
The small tortoiseshell butterfly (Aglais urticae) was also enjoying the oregano!Top tip!
Remember, as a double bonus, you can still clip a few of the fragrant leaves to add to your cooking – (this ‘pizza herb’ not only offers flavor, it has anti-oxidant properties too2. Better still, dry the leaves and store them for use later.
Pick the leaves before the flower buds open.
