季節のハーブガーデン：多年草によるレイヤリング

Design a hotel garden in the manner of Piet Oudolf, planted for structure and seasonal change rather than flower colour. Fill broad organic-shaped beds with a rich matrix of perennials and ornamental grasses, intermingled rather than blocked, with strong emphasis on seed heads, stem structure and texture — echinacea, eryngium, sanguisorba, molinia and calamagrostis in muted russet, bronze, straw and soft purple. Let the planting reach chest height in places and spill over the path edges so the visitor walks through rather than beside it. Cut a simple narrow path of compacted gravel or stone through the mass, curving gently. Keep the hard landscape minimal: one long low corten steel edge, one simple timber bench. Add a few multi-stem trees rising above the perennials. Show the garden in late autumn as the planting goes over, with seed heads catching low backlight and the colours entirely in browns and golds. Photorealistic, naturalistic, textural and atmospheric, eye-level view along the path.
