This blue hosta is meant to invoke a waterslide, and that it does with wavy, ruffled leaves that are pointed at the tip and the colour of a deep blue sea. Lavender flowers appear on flower scapes in late summer and attract bees and butterflies. Hostas are very popular perennials chiefly due to their versatility. An ideal choice for a shade garden, as a border plant or in a container on the patio, hostas are a dependable grower and even thrive in a city environment. The Waterslide will grow to 14 inches in height with a spread of 32 inches.
