Partially white hosta is easy and less care plant. The problem with the  partially white hostas is that there is no chlorophyll in the white tissue. The white part of the hosta cannot produce the food for their root and need this issue in green part of leave so the more part of white in leave is harder growing rate.  The partially white hostas will demand more light than other hostas but it wants to be indirect sun. Too much direct sun can burn the white part of the leaf. Morning sun is the best for them.

Too much shade also causes their color of leaf unexpected.

Partially white hosta needs an adequate of water. Water and sun are the factor of their maturity

The difficulty of growing white hostas, consider the ratio of white to green in the plant. As a general rule, the more white tissue there is, the more sensitive the plant and the more particular it , white leaf tissue is often thinner, making it more susceptible to burning or melting-out by sunlight. They are also note to be slow growing because of fewer number of chlorophyll to create their own food.
