Plant badge

[1] They are usually worn affixed to the bonnet[2] behind the Scottish crest badge,[3] or pinned at the shoulder of a lady's tartan sash.

An authentic example of plants being used in this way (though not by a clan) were the sprigs of oats used by troops under the command of Montrose during the sack of Aberdeen.

Also, a number of the plants (and flowers) attributed as clan badges are only available during certain times of year.

Even though it is maintained that clan badges were used long before the Scottish crest badges used today, according to a former Lord Lyon King of Arms the oldest symbols used at gatherings were heraldic flags such as the banner, standard and pinsel.

Another large group is the Clan Chattan group (clans Mackintosh, Macpherson, Macgillivray, Macqueen, Macbain, Farquharson, Davidson) which have been attributed red whortleberry (sometimes called cranberry in Scotland), or bearberry, or boxwood.
