Yes, both of my xAmarcrinum memoria-corsii clones are fragrant, one is the clone 'Howardii' the other one was unnamed, but there is little difference so it might also be 'Howardii'. And I guess that my Amaryllis only survives the Danish winters because I mulch with 15 cm of dead leaves and some evergreen prunings on top.
By the way, has anyone ever tried to cross Amaryllis belladonna with Crinum bulbispermum to get Amarcrinums with striped petals?
