Miss Willmott's Ghost Eryngium giganteum
ABOUT
Eryngium giganteum, commonly known as Miss Willmott's ghost, is a strikingly architectural plant that commands attention with its unique appearance. The focal point of this species is its flower head, which has a dome-shaped form composed of numerous small flowers tightly packed together, creating a thistle-like effect. These flower heads are a subtle shade of silver or steel blue, providing a ghostly shimmer that befits its common name. The foliage of Miss Willmott's ghost is likewise arresting, with leaves that exhibit a somewhat spiny and serrated edge, adding to its jagged charm. The leaves are often a bluish-green hue, which contrasts beautifully with the silver-blue flowers, enhancing the plant's overall silvery appearance. Both the flower heads and the foliage are covered in a fine, powdery texture that contributes to the ghostly aura of the plant. Adding to its distinctiveness, Miss Willmott's ghost produces a basal rosette of leaves from which the flower stems arise. The stems carry the characteristic bracts that are spiky and similar in color to the flowers, enveloping them like a ruff and extending the otherworldly effect throughout the plant. Miss Willmott's ghost is a biennial or short-lived perennial, which means it completes its life cycle in two years or can persist for a few years with proper conditions. It is often planted for its striking structural quality and is used to provide contrast and interest in garden borders and gravel gardens, where its ghostly appearance can be appreciated fully. Its unique color and texture make it a favorite among gardeners seeking to add a touch of the ethereal to their plantings.

During the growing season, water the plant once a week with about 1 to 1.5 gallons depending on the size and the environmental conditions. Reduce watering frequency in the winter to every two weeks or less, depending on the climate and indoor conditions, as the plant is dormant and requires less water.

- Temperature
Sea Holly is tolerant of a wide temperature range; however, it grows best in temperatures between 60°F and 75°F. It can survive temperatures as low as 0°F and as high as 90°F. Ensure that it is not subjected to prolonged periods at these extremes to prevent stress on the plant.
- Pruning
Prune Sea Holly in late winter or early spring to remove any dead or damaged foliage and to shape the plant before new growth begins. Pruning can also be done after flowering to tidy up the plant, but this is not essential as the seed heads provide winter interest. Generally, pruning once a year is adequate.
- Cleaning
As needed
- Soil

- Life cycle
Eryngium giganteum, known as Miss Willmott's ghost, begins its existence as a seed that typically germinates in spring, if sown in autumn or winter. The seedlings develop a rosette of leaves during their first growing season, focusing on establishing a strong root system. In the second year, the plant sends up a tall flowering stalk, which can reach up to 3 feet in height, and is adorned with a large number of small, pale silvery-blue conical flower heads surrounded by spiny bracts. After flowering, usually from June to August, pollination occurs, often facilitated by insects attracted to the plant's nectar. The plant sets seed and, being a biennial, it dies after seed maturation and dispersal. The seeds remain in the soil to begin the next generation or can be collected and sown by gardeners to propagate new plants.
- Propogation
Propogation time
Early summer
The most popular method of propagation for Eryngium giganteum, commonly known as Miss Willmott's ghost, is by sowing seeds. The best time to sow Eryngium giganteum seeds is in late summer or early autumn. Seeds should be scattered lightly on the surface of a well-drained seed starting mix, and then gently pressed into the soil without covering them, as they need light to germinate. Keeping the soil lightly moist and providing a cool, yet not cold, environment will encourage germination. After the seedlings have developed true leaves and reached a suitable size, they can be transplanted into their final position in the garden. Care should be taken to not disturb the root system too much during transplantation, as this plant prefers minimal root disturbance.
