Stately vase-shaped form with silvery-blue leaves on long stems. Tall lavender flower spikes rise five feet above the foliage.
Toxic to cats and dogs, which surprises people because hostas look so unthreatening and sit right at nose height. Eating the leaves causes vomiting and diarrhoea. Rarely serious, but a dog that grazes a whole clump will have a bad night.
