The letter Úr

The heather in Celtic tradition
Heather covers the open hills and moors in a wash of purple, close to the ground and rooted in poor, exposed soil where little else thrives. That closeness to the earth gave it associations with grounding and with a passionate, earthy warmth, and its rich purple bloom tied it to feeling and to the heart. Heather was a source of heather honey and of dye, and white heather in particular was carried as a token of good luck. It is a plant that draws beauty and sweetness out of hard, open ground.
What Úr means in ogham
In modern ogham practice, Úr is read as passion, healing, and grounding, a sign of warm feeling rooted in solid ground. The reading follows the heather’s earthy home, its honey, and its ties to luck and the heart. 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.
Heather in the Celtic tree calendar
As one of the vowels, Úr 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.
