Plantain Lily 'Royal Crest' (Hosta × 'Royal Crest') is a dependable, large hosta that gives you a polished mound of thick, shiny green foliage and tall spikes of very fragrant, near-white flowers in late summer. Use it to bring bold texture to beds, borders, and shaded foundations, or to anchor mixed perennial plantings where you want a strong, clean green backdrop.
Give your hosta rich, moisture-retentive soil that still drains well, and keep it evenly moist during hot, dry stretches. It tolerates full shade and part shade easily; with consistent moisture it can also take more sun than many hostas. A spring layer of compost helps keep the root zone cool and steadily damp, and a light mulch can reduce temperature swings and conserve moisture.
At maturity it reaches about 25-28 inches tall, with a broad spread, so plan for room to fill out. You can divide established clumps in spring or after flowering to rejuvenate and to share plants. The fragrant blooms can draw butterflies, and the sturdy flower stalks make nice cuts for simple indoor arrangements.
