Commonly known as a curry plant, this tender perennial has silvery foliage and a structure similar to lavender, but exudes the smell of curry. As delicious as that sounds, Helichrysum angustifolium is not generally considered a culinary herb (though it is used for medicinal purposes) and is more commonly grown for its aesthetic value. Mounding 12 to 24 inches tall and spreading up to 36 inches wide, this sun-loving, narrow-leafed perennial sends up clusters of bright yellow flowers in the summer. Like lavender, it can handle less fertile soil as long as it drains well. Hardy to 10 degrees, we treat this plant as an annual in container planters, hanging baskets, and in borders, though it may winter over if given protection.
