Misopates orontium aka Corn Snapdragon

Misopates orontium is a small annual known as lesser snapdragon. Other names include calf’s snout and weasel’s snout. Its older name is Antirrhinum orontium. Kew places it in the plantain family, Plantaginaceae. Its native range spans Macaronesia, the Mediterranean, and northeastern Sudan. It has also spread beyond its native range. North Carolina State records it in Canada and the United States. There, it has become a naturalized weed in some areas.

The plant grows upright and forms several stems. These stand without support and have no scent. The lower stem is smooth, while glandular hairs cover its upper parts. Its green leaves feel rough and have a simple form. They range from narrow to oval, with smooth edges. Some leaves may have lobes, but none divide into leaflets. Lower leaves grow in opposite pairs along the stem. Higher leaves take turns on either side.

Flowers appear in spring and form clusters called racemes. They look like small snapdragon blooms, with joined flower parts. Each bloom measures less than 0.08 feet [0.025 metres] across. Pink flowers feature in North Carolina State’s account. The same source also lists blue, purple, and red shades. Hairy green fruits follow the flowers in spring and summer. Their shape gives the plant its weasel’s snout name. The fruits turn dark brown as they mature. Once dry and ripe, they split open.

Lesser snapdragon grows in full sun or partial shade. It suits slightly acid to neutral soil and tolerates poor ground. Listed soils include clay, sand, and shallow, rocky ground. Moist soil with good drainage meets its stated growing needs. It also occurs in wetlands and on disturbed land. North Carolina State lists USDA hardiness zones 3 through 6. The plant grows at a moderate rate and needs little upkeep. Growers can raise new plants from seed.

Garden uses include rock gardens, pots, and hanging baskets. Its flowers also suit wildflower plantings and areas left to naturalize. Yet its spread can make it a weed. Growing it in a pot offers a way to limit spread. North Carolina State reports no known insect pests or diseases. That source also marks it as non-toxic to cats, dogs, and horses. The supplied sources give no edible uses or human safety assessment.
