Asparagus does best with a chilling period, but there are cases where it can be grown in a tropical environment. One source says it can be done as long as there is a long enough dry season to induce dormancy. Here is an article about growing it in Hawaii, which says that it does not undergo winter dormancy, so it can be harvested several times a year. There are instructions about how to induce dormancy during the drier summer months.
