Hi Shirley – wow, that's an impressive amount of amaryllis! Thanks so much for opening my eyes about Benlate and Benomyl. I was not aware of it being taken off of the market, nor of the risks involved. Clearly, my sources for advice are outdated suddenly. Thanks for sharing this.

Thank you! I wanted this answer. I was getting confused when I was looking up Amaryllis. Some websites write that they are the same plant.

The statement "native to the Cape of South Africa" does not apply to the plants with the common name "amaryllis" and which are the subject of your article. The plants in your article are in the genus Hippeastrum and they occur only in the New World in South America, Central America, and the Caribbean. The amaryllis native to the Cape of South Africa is Amaryllis belladonna and has the common name of "naked ladies" or "belladonna-lily." I know this is confusing but the plant whose scientific name is Amaryllis belladonna is not the flowering bulb with the common name "amaryllis." And the plants with the common name of "amaryllis" are not in the South African genus Amaryllis, but rather, in the New World genus Hippeastrum. See the Wikipedia entries for "Amaryllis" and "Hippeastrum" for further details.

The statement "Amaryllis are designed to go ‘dormant’ once the winter rains pass, and the bone dry summer arrives" applies to the South African Amaryllis belladonna. The New World Hippeastrum species and hybrids, which are the subject of your article, come from extremely diverse habitats but none of the species, or hybrids derived from those species, that are the topic of your article are winter growers that are dormant for half the year during a bone dry summer.
