Reaching skyward with golf ball-sized spherical blooms, this striking globe thistle cultivar commands attention through its silvery white flowers and architectural presence. The 2" spiky globes emerge atop sturdy silvery stems that rise 36–48" from a base of deeply cut, dark green foliage with distinctive grey undersides. Despite its thistle-like appearance, Star Frost's leaves are surprisingly soft with a downy texture. A robust, drought-tolerant perennial that flowers in its first year, it provides dramatic visual interest while serving as a pollinator magnet for bees and butterflies. Create maximum impact by mass planting along walkways, positioning at the centre of borders or incorporating into foundation plantings. The long-lasting blooms excel both in fresh arrangements and dried everlasting displays.
