Miss Willmott’s ghost (Eryngium giganteum) is originally native to the Caucasus and western Iran. It grows there on barren, stony locations like rock steppes. Botanically, the plant belongs to the plant genus Eryngium. This is also commonly referred to as eryngo or sea holly. It contains over 200 different species, some of which give off decorative garden shrubs such as the Alpine sea holly (Eryngium alpinum) or the Mediterranean Sea holly (Eryngium bourgatii).

Characteristics of Miss Willmott’s ghost
The Miss Willmott’s ghost grows as a biennial plant or short-lived perennial. As is typical for two-year-old plants, only one leaf rosette grows in the first year and an inflorescence only appears from the second year of life. Thanks to its long taproot, the plant is well adapted to dry locations. The plant grows to around 80 centimeters (32 in) high and is hardy.
The leaves of the Miss Willmott’s ghost form a basal leaf rosette that is about 50 centimeters (20 in) in diameter. The base leaves are heart-shaped, colored medium green and up to 16 centimeters (6.4 in) long. The stem leaves are ovate tapered and toothed. They are decorative white veined and have a rough texture.
The actual inflorescence of Eryngium giganteum is surrounded by striking bracts that are strongly serrated and silvery in color. This serves the plant in nature to ward off predators such as wild goats. The branched inflorescence consists of cylindrical umbels about six centimeters (2.4 in) long. These contain numerous bluish flowers that are a magnet for bees and many other insects. Miss Willmott’s ghost blooms from July to August. But even after that, the inflorescences look attractive for a long time. If you want to dry them, cut off the inflorescences before they open.
