Sum and Substance Hosta
Chartreuse giant that can take more sun than most hostas. Heart-shaped leaves grow enormous.
Dangerous to cats
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.
