This is the North American substitute for the European Furze or Gorse. Both Gorse and Goldenrod grow everywhere as yellow-flowered weeds in poor or otherwise barren soil. Gorse is a prickly plant, and Goldenrod is irritating to many people's immune systems. The Ogham teaching poem identifies Ohn as "I vam the blaze on every hill." which well describes a field of goldenrod in bloom.

Ohn is the ogham of gold and gathering together. It speaks of honey and hives, coins, wealth and sweetness on the material plane. It is linked to the rune Feoh, the rune of cattle and possessions. It is important to remember, though, that the secondary meaning of Feoh is slavery, and the Norse adage that explained the rune is "Wealth causes friction between relatives, while the wolf lurks in the woods." This is the wealth ogham, not the happiness or comfort ogham. Possessions are necessary and useful, but they do not give meaning or spiritual richness to our lives.

The bird paired with Ohn is the magpie, the bird that steals trinkets and coins and gathers together a hoard. The Magpie is also known as a squabbling bird that quarrels with its neighbors. The archtypical Magpie in fable is a bird who tricks and is tricked, trying to get something of value for nothing. Gold sets the traps of cheating and dishonesty to trick the gullible into thinking that worth is set by monetary value alone, and not by some higher standard.

Ohn can be used for spell working, but it is always wise to pair it with an ogham or rune that has a more spiritual meaning for balance, or to use it only with a clear and limited desire. Many teaching stories exist in every culture of the foolish person who wishes for wealth only to find that the price to be paid is something far more important.

The message of the reversed card is first of financial difficulties but also of incompleteness or of something lacking. This is a useful rather than an oracular card and, when in balance, sends a message of sweetness. When we are given this ogham we should keep in mind that "Enough is as good as a feast."
