Crinum ‘Ellen Bosanquet’ is a spectacular red lily for zones 6 thru 10.  The strap-like leaves stay evergreen down to 25 degrees while the bulbs are hearty to 0 degrees.  The blossoms are fragrant and can produce up to 20 per bulb in mid- summer (June).  They are perfect in sun to partial shade and should be planted 1 to 3 feet apart for a wonderful display.
