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?
