Hi: Arnold is right, there are no Eustephias native to Argentina, Eustephia "jujuyensis" being a species of Hyeronimiella. Eustephias can be grown as hybrid Hippeastrums, dry winter dormant and with warmish conditions the year round. They come from high altitude subtropical forests where it is a bit chilly in winter when the bulbs are dormant. That the bulbs are dormant in summer does not seem to follow the natural pattern. They offset well and provided not infected with viruses are extremely long lived if the drainage of the mix is really good.
