The Orchids Limited website has a listing for a Phal that is white with yellow throat and states that it is rarely available and not in many collections: Phalaenopsis amabilis var. grandiflora (Winter Sunset x Snowflake and Reciprocal).https://www.orchidweb.com/orch...
I'd think it would require the same care and culture as any other Phalaenopsis.
