I'm not sure how to care for this in my climate?

Usually I would plant the bulb in spring after frost past, in potting soil with perlite. It would continue to grow until frost approaches then I bring it inside, cut leaves off, and store bulb in my basement until it's time to plant in spring again.

Will that work for this plant or must it always be kept growing year round, as in planted inside during cold weather and outside in warm weather? And will it hybridize with amaryllis?

Keith, that's an unusual one you have. I had to do some research on this. Its a H. species growing in Brazil. Check out the Pacific Bulb Society website. Its is an evergreen, which are treated a bit differently than the usual H. hybrids. They keep their leaves through a short summer dormancy, so I wouldn't cut it back. When you bring it inside, to protect from frost, treat it like H. papilio, let it keep its leaves through the winter. It should go dormant during the summer, blooming again in late summer. Reduce or stop watering in mid summer, start watering again in mid August. It might hybridize with the H. hybrids, since H. papilio does hybridize. The problem would be the different blooming times. We'll be interested to see how this fares out in your garden.
