Onn is the seventeenth letter of the ogham alphabet, written ᚑ, and it is linked to the gorse, also called furze. It carries themes of hope, energy, and gathering, drawn from a bright yellow shrub that seems to flower almost all year round. This page covers the letter, the gorse in Celtic tradition, and what Onn is taken to mean. For the whole alphabet see the ogham letters guide, and for every symbol at a glance, the ogham symbols page.
The letter Onn
Onn is the second of the five vowels, written as two notches on the central line: ᚑ. Its sound is O. In the traditional order it follows Ailm and comes before Úr.
The gorse in Celtic tradition
Gorse is famous for its blaze of yellow flowers, and for the old saying that when gorse is out of bloom, kissing is out of season, a joke that works because gorse is almost never fully out of bloom. That near-constant flowering, and the bright, sunny color, tied it to hope, to warmth, and to the sun itself. Its flowers are also a rich early source of food for bees, so the plant carried ideas of abundance and of drawing good things together. Gorse was even used to gather and hold, planted as a tough hedge for livestock.
What Onn means in ogham
In modern ogham practice, Onn is read as hope, energy, and gathering, a sign to keep a bright outlook and to draw resources or people together. The reading follows the gorse’s sunny, near-endless bloom and its use as a plant that collects and holds. As with every few, the plant’s qualities are old while the tidy one-line meaning is a modern reading. See the ogham symbols and their meanings page for the full set.
Gorse in the Celtic tree calendar
As one of the vowels, Onn is not one of the thirteen monthly trees in the Celtic tree calendar, so it does not mark a birth-month sign. In the modern system the vowels are sometimes tied to the sun’s turning points rather than to a month. For the trees that form the calendar, see the Celtic tree calendar and find your birth tree guides.
