Uniquely identifiable characteristics : rub the leaves and smell the wonderful aroma. No other plant produces a smell quite like this one does. Describing a small is fairly difficult, but you'll know you've seen bog myrtle when you smell this.

Distinguishing Feature : The short knobbly woody stem and the dark-green lanceolate leaves. Your feet will likely be very wet too, for you will be standing in a bog!

Lookee-Likees : At first glance, Bog-myrtle could be mistaken for a small Rhododendron or Laurel bush.

No relation to : Chilean Myrtle (Luma Apiculata).

Bog-myrtle grows only in wettish peaty soils typical of upland acidic bogs. The roots employ nitrogen-fixing actino-bacteria to fix nitrogen and help it flourish in the nitrogen-poor peat bogs.

An entrancing sweet-smelling resin comes in evidence when the leaves are crushed between the fingers. A large straggle of Bog Myrtle in the sodden hills can be smelled from half a mile away.

Bog Myrtle has quite a reputation for repelling midges and fleas, and has been used many times in the past and even recent past for such duty, no doubt due to the odorous resin. A midge repellant called 'Myrica' made by steam distilling the volatile oil from Bog Myrtle was sold by a Scottish company in the Isle of Skye. It was found to be very effective on Scottish midges.

But it has an even bigger reputation as a substitute for hops in brewed alcoholic beverages. If ever the author were to brew a beer made from Sweet Gale, he would name the beer Regale! There is a Scottish brewery, Fraoch, that is brewing a Heather Ale using Heather and Bog Myrtle from the extensive crops on Scottish bogs.

The flowers are borne in catkins, the orange are male, the female are red, and are on separate-sexed plants. There are only photos of one sex here, I need photos of the other sex. A yellow dye can be extracted from Bog Myrtle.

Myrtenol is the resinous substance in Bog-Myrtle responsible for its pleasant aroma and its insect repellent and beverage flavouring properties. As can be seen it is chemically related to Verbenol, another terpene which is found in some species of Verbena plants (Vervain), and in terpentine, a solvent for good paints. Both have the configuration, if not the structure, of cubane.
