With most genus of plant these days, there are a myriad of varieties to choose from. Unless of course you are looking at a monotypic genus, Sciadopitys or…
Cultivation
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.
Propagation
Propagate by division of the fleshy crowns in early spring. Seed raised plants very rarely come true to type (except H.ventricosa).
Pests, diseases or disorders
Slug and snail control is essential. Prone to vine weevil.
Good drainage is important to prevent winter crown rot in over-wet ground.
