This grower is sure of this plant identification.
Another cracking large blue. Unusual in that it has more elongated leaves than most of it's rivals, due to a bit of Hosta montana in it's lineage. Will make a plant up to 1m tall by 1.5m wide. I like the bold, pale, slightly frilly looking flowers in mid summer, demonstrated well in the photograph here, which seem to complement the foliage well.
Hosta sieboldiana ‘Blue Angel’. This species will produce large blue-green, heart-shaped leaves which will form a lush mound of foliage. The flowers are lilac to lavender and will appear on short stems just above the foliage in late spring and early summer. You can plant them in masses; they will form a stunning ground covering for under-planting with large trees. The soil should be rich, moist and well drained.
All Hostas need some shade and few will thrive in open strong sunlight. A general rule is that the lighter foliage, the brighter the sunlight that will be tolerated. Variegated varieties tend to require more sun to keep their white, light green or gold stripes. The darker, bluer varieties need more shade.
Once established, Hostas are pretty tough and will spread horizontally to make excellent ground cover.
