Plant Description

Individual, erect, cottony stems grow 1-3 ft. tall and are often clumped together creating a bushy appearance. Narrow leaves are gray-green to woolly-white. Globular flowers are actually long-enduring, white, dry bracts arranged around a yellow center. Several evenly leafy woolly stems in a small patch are topped by a crowded, roundish cluster of flower heads with pearly-white bracts, sometimes with a dark spot at base of each outer bracts. The dried stalks with their pearly-white heads are attractive in floral arrangements. The pure white flower is commonly used in dried flower arrangements. Good dried flowers; food plant for Painted lady butterflies.[2]
