Hosta sieboldiana aka Blue Angel Hosta
Taxonomy
Hosta sieboldiana, also known as Siebold's plantain lily, is a popular species of hosta native to Japan. It is a large, clump-forming, herbaceous perennial with broad, ovate, and blue-green foliage that has prominent veining and a wavy edge. During the summer, it produces white, bell-shaped flowers on stems that can reach up to 80cm in height. This variety of hosta, specifically Hosta sieboldiana var. elegans, has been awarded the Royal Horticultural Society's Award of Garden Merit, as has a variety of its synonym, Hosta fortunei var. aureomarginata, known as the gold-edged plantain lily. Additionally, the cultivars 'Blue Angel', 'Blue Mammoth', and 'Olive Bailey Langdon' have also received the RHS Award of Garden Merit. While hostas are favored for shady areas, this particular hosta is considered a garden classic due to its large, powdery-blue, heart-shaped leaves. It is known to be slightly less palatable to deer, although they may still enjoy eating it. Hosta sieboldiana can be easily divided in either spring or fall, and the dying foliage can be removed before mid-spring. It is a resilient plant with good slug resistance and can be left undisturbed for years.
