Eryngium amethystinum var. euspinosa was collected from grassland in the Tuscan hills in which mature plants were growing in abundance at c. 900m. The plants can be found through the Mediterranean region, preferring an alkaline soil. A mature plant is now thriving in the rock garden.
The clump does fall apart in the centre as the weight of its growth develops. The flowers, opening metallic violet, attract all manner of pollinating insects. It is a desirable specimen when in full open bloom, one which needs an open sunny situation, plenty of space and ideally support to utilise its full potential.
