Why is vervain called a sacred herb?
Nothing about the plant looks important. It is a sparse, branching herb of dry verges with a few small pale flowers on long spikes and almost no scent. Yet the Romans called it the sacred herb, and its Latin name, verbena, was the general word for the foliage carried in their rites.
The lore that built up around it is unusually consistent. It is a plant of bonds and peace, borne by envoys and used to sweep altars. It is a plant of second sight, used in casting lots. And it is a plant of protection, hung in houses and worn against harm. A later Christian story says it was first found growing on Calvary, which gave it the name herb of the cross.

What sets Vervain apart
Vervain's standing comes from office, not from appearance or chemistry. It was the plant that made an envoy inviolable and an altar clean, so its associations are legal and priestly: oaths, treaties, purity, the binding word. That sets it apart from the showier magical herbs, which are valued for scent or poison. The detailed gathering rite Pliny records, with its timing, offering and iron circle, became the pattern for ceremonial herb gathering in later books of magic.
- Botanical name: Verbena officinalis
- Roman names: verbena, herba sacra, and in Greek hiera botane
- Roman use: carried by fetial envoys; used to sweep the altar of Jupiter
- Pliny's rite: gathered at the Dog Star's rising, with honey offered to the earth
- Christian name: herb of the cross, from a legend of Calvary
Often mistaken for something else: Lemon verbena, Aloysia citrodora, is a scented South American shrub brought to Europe in the eighteenth century; sacred vervain is the scentless native Verbena officinalis.
The story behind Vervain
Roman envoys called fetials carried sacred herbs, verbenae, when making treaties. Pliny the Elder writes that the Gauls used vervain for drawing lots and foretelling, and that the Magi wanted it gathered at the rising of the Dog Star, when neither sun nor moon was looking, after an offering of honey to the earth, with a circle of iron drawn round it and the left hand used to lift it. English charms written down from the sixteenth century bless the plant as it is picked, and a rhyme pairs it with dill as a herb that hinders witches.
Why Vervain matters
Vervain shows how a plant can be sacred by custom alone, with no striking look, scent or effect to explain the honour paid to it.
How to read Vervain
Dried sprigs are tied in protective bundles, added to water for sprinkling a threshold, or kept with papers on which a promise is written.
Vervain in practice: an example
An old English charm has the gatherer say, as the stem is plucked, that vervain was first found on the Mount of Calvary.
Where readings of Vervain go wrong
The rites Pliny reports are hearsay about peoples he did not know well, so they are evidence of Roman belief more than of Druid practice.

Common questions
Why is vervain called a sacred herb?
The Romans used it in religious ceremony and treaty making and named it herba sacra. Pliny adds that the Gauls and the Magi honoured it, and Christian legend later tied it to the crucifixion.
Is vervain the same as verbena?
Verbena is the Latin and botanical name, and vervain is the English form of the same word. The garden verbenas grown for colour and the lemon verbena used for scent are different plants from the wild sacred one.
Did the Druids really use vervain?
Pliny says the Gauls used it for lots and prophecy, and writers since have attached this to the Druids. There is no native Celtic record of the practice, so it rests on that one Roman report.
