Happy to help . Crinums are just so cool. They do belong to the Amaryllis family, so that and lead to a bit of confusion as to which plant they are.
I have loved Crinums since my Mother-in-law asked my husband to please come help his dad dig up the ones in her yard. That was 40 years ago and it took us a weekend to coax and cajole 30 bulbs and their Mother from the ground. They are Crinum asiaticum, Giant Spider Lily. My father-in-law did admit (with a bit of a grin) that a few would disappear every now and then. They were there when my in-laws bought the house...planted over an old septic tank.
The Mother bulb was huge...weighed in at about 14-15 pounds after we washed away the soil. Since then, I have continued to pass them along.
