Mexican Sea Holly
Eryngium proteiflorum is native to Mexico and forms a wide rosette of thick, spiny, linear leaves and theatrical flowers from July to September; prominent, greyish-blue cones surrounded by silver-white bracts.
The plant can grow up to one metre in height, with 30 cm long leaves, 10 cm bracts and 7 cm cones. Well, Eryngium proteiflorum obviously does nothing by halves and is like a pineapple for its habit and a protea for its flowers! No more, no less!
In the garden, you can use its architectural habit to add an exotic touch to a bed of grasses with lighter structures (Stipa tenuifolia, Stipa ichu). In climates with damp, harsh winters, you can grow Mexican Sea Holly in a pot on a sunny patio.
Grow in full sun in ordinary, gravelly, sandy, fertile soil, which is well drained in winter. Hardiness: - 12°C. Excellent cut flower (fresh or dry).
