Hosta clausa var. clausa

Description

Great foliage plants, very architectural, relatively disease free, easy to grow, long lived, well behaved and unfortunately slugs and snails like them to. Growing them in pots is a solution.
The other is that we have to manage our gardens more ecologically, giving predators like frogs and hedgehogs a healthy environment to live in. This Hosta is a particularly good ground cover for around the base of trees.
