Alder

Botanical Name: Primarily Alnus glutinosa (black alder, common in Europe); Alnus rubra (red alder, Pacific Northwest); Alnus incana (grey alder); Alnus serrulata (tag alder, North America). Folk Names: Alder tree, black alder, red alder, owler, aller, aller tree, gallows tree (in some folklore), water elder, Welsh oak. Parts Used: Bark (especially inner bark), catkins (male/female flowers), leaves, twigs, occasionally wood (for carving or burning). Forms Used: Dried bark for teas/washes (external magical use), chips for incense, twigs for wands/besoms, bark powder for sachets, wood for protective carvings.

Note on Identity Alder is a fast-growing, water-loving tree in the birch family (Betulaceae), often found along rivers, streams, and wetlands. Its bark turns red when cut (hence red alder), and it fixes nitrogen in soil, making it a pioneer species. In occult traditions, alder is a powerful protective, oracular, and underworld-linked tree—associated with both life-giving water and death/transition due to its reddish sap (symbolizing blood) and use in ancient shield-making and corpse preservation.

History and Etymology

The name "alder" comes from Old English alor, related to Germanic aliz and Proto-Indo-European el-, ol- ("red" or "yellow-brown"), referring to the bark/wood color. Latin alnus is of similar root.

In Celtic mythology, alder was sacred to Bran the Blessed (whose name means "raven" or "crow," birds associated with alder); his head was buried for protection. Alder was used for coracle frames, shields (its wood is light yet strong), and dyeing (red from bark, black from catkins). In Irish lore, the first man was made from alder (with hazel for the first woman in some versions).

Ancient Britons used alder for tanning leather and preserving bodies (its tannins inhibit decay). In Norse and Germanic traditions, it was linked to the gallows (hence "gallows tree" in some dialects) and to water spirits/faeries. Medieval herbals used alder bark for wounds, fevers, and as a mouthwash.

In modern Druidry, witchcraft, and folk magic, alder is valued for protection (especially near water), divination (oracular), and transition magic (death/rebirth, courage in change).
