These included: The Beaufort Portcullis, now the symbol of the House of Commons; The heraldic colours white and blue, an old symbol of the Earls of Lancaster, shown componée; The Beaufort Yale, an heraldic beast used as supporters of the escutcheon; The Forget-me-Not flower (Myosotis sylvatica), a reference to the heraldic motto of Lady Margaret Beaufort Souvent me Souvient ("I often remember"). It is visible sculpted on the main gate of St John's College, Cambridge, founded by Lady Margaret Beaufort. The forget-me-not flower was possibly first used as the heraldic badge of King Henry IV, legitimate son and heir of John of Gaunt. One of Henry IV's mottos was souveyne vous de moi, the French name for the forget-me-not flower. Henry IV's accounts contain several references to this flower, for example "for mending a collar of the lord in the form of flowers of souveyne vous de moi … with a swan newly enamelled" and "for a collar of esses and flowers of souveyne vous de moys".
