The vegetable lamb is considered a monster in Society heraldry, a mythical plant bearing young sheep as its fruit. It was first mentioned in the Travels of Sir John Mandeville, c.1371, but does not appear in mundane armory.
Society blazon uses the phrase “fructed” to refer to the full blossom, including the sheep (e.g., when of another tincture than the rest of the plant). If only the sheep’s tincture differs, the phrase “fructed of sheep” is used: that is, a “vegetable lamb vert fructed sable” has black blossoms and sheep, bujt a “vegetable lamb vert fructed of sheep sable” has green blossoms and black sheep.
Lysander Keisalovitch bears: Argent, a vegetable lamb vert.
Solange Sarrazin bears: Or, a vegetable lamb vert, flowered gules and fructed of sheep argent, a chief indented azure.
Áine Táilliúir bears as a badge: A vegetable lamb Or fructed of sheep sable.
