Alpine Eryngo 'Blue Star'

Eryngium alpinum 'Blue Star' | Also known as: Alpine Sea Holly 'Blue Star' | Rating: 0 votes | Print / Pdf

Eryngium alpinum, or Alpine Eryngo, is a delightfully different plant that sports heart shaped leaves and purple blue blooms during the summer and autumn months. These blooms are vivid in colour, and very spiky in appearance, adding a touch of the exotic to your garden. Despite its looks, this plant is thankfully easy to grow and requires little on-going care. Plant in full sunlight for the best results, it is a wonderful addition to flowerbeds and borders, a wild flower area of the garden, and is often used in cut flower arrangements.
