 In 1946, two Dutch growers moved to South Africa and began cultivation there. Although most cultivars of Hippeastrum come from the Dutch and South African sources, bulbs are now being developed in the United States, Japan, Israel, India, Brazil and Australia. The double flowers from Japan are particularly beautiful. Nurseries may list Amaryllis bulbs as being 'Dutch', 'Israeli', 'Peruvian' etc., depending on the country of origin.
