The original! One of the first Hippeastrum Hybrids, and still one of the best. Also called St Josephs Lily and Hardy Amaryllis. This sought after Southern Heirloom thrives in typically bad southern conditions. You can expect them to multiply, so be prepared to share with friends. Unfortunately, many heirloom bulbs have picked up plant viruses and diseases over the years. This slows down their growth and dims their vitality. These bulbs have been cleaned through tissue culture and tested virus and disease free. We have grown them for a year here and the bulbs are now 1-2" across (they never get as big as modern armaryllis). They have excellent root systems and we will make an efford to save these roots when we dig them up for you.

Deep velvety red trumpets are born atop the thick sturdy stems of this hardy Amaryllis. A wonderful and easy slowly multiplying bulbous perennial.
