Origanum × majoricum
Common name(s): hardy sweet marjoram
Description: perennial; a hybrid of true marjoram, (O. majorana) and wild marjoram/oregano (O. vulgare) which has inherited the sweetness of O. majorana and the increased hardiness of O. vulgare. Used widely as a perennial substitute for true marjoram in temperate gardens. This plant is sometimes sold under the name 'Italian oregano' but I'd wager most Italians are cooking with Origanum hirtum subsp. hirtum. Mostly sterile and self-contained in the garden. White flower clusters in summer.

Position: full sun and well-draining soil
Uses: culinary-soups, stews, pizzas, sauces, etc., to attract pollinators
Winter Hardiness: to 10 F and below
