This rarely available gem is one of the best white-centered forms of H. 'Fortunei' (often incorrectly listed as H. 'Undulata'). The clump spreads to a width of 2' with age. H. 'White Christmas' is truly one of the most attractive and distinctive hostas on the market, needing plenty of morning sun to grow best. In shade, the clumps tend to fade to green in very late summer. The clumps are topped with typical light lavender Fortunei-type flowers in late spring.
