Hosta lilies may be the most versatile and commonly grown perennials for the shady garden, with foliage in a variety of shapes, colour and sizes. The first Hosta with yellow flowers? The delightful Miracle Lemony! Bell-shaped flowers are a vivid yellow, with a fragrance hummingbirds seemingly adore. Leaves are light green and wavy. Compact plants. Needs rich, moist, well-drained soil.
