Description
Sea Holly makes a superb hardy perennial for hot, sunny borders. Thriving on gritty soils, it is tough, resilient and reliable. This variety boasts a compact habit, and attractive, sculpted foliage. The silvery stems are topped with domed flowers and surrounded by a delicate collar of soft green bracts. The small green globes mature through silvery-blue to a deep indigo colour as summer progresses. Eryngium 'Magical Blue Globe' is perfect for bringing texture to the front of borders, especially in challenging coastal regions. It also makes a fine cut flower, either fresh or dried. Height: 50cm (20"). Spread: 40cm (16").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Grow sea holly plants on light, well drained soil in full sun. Eryngium plants particularly dislike cold, wet soil in winter which may cause the crown to rot. If planting on heavy soils, dig in plenty of coarse grit to improve drainage prior to planting.
More Info
Feed and water regularly throughout the growing season until plants are fully established. Leave faded eryngium flower heads in place until spring to benefit from the winter interest they will add to your borders. In cold wet soils, use a cloche to protect the crown of the plant from winter rainfall. Lift and divide overcrowded clumps of eryngium in spring. Only lift it when necessary as sea holly can be slow to re-establish.
