Mark, the only problem with calling the double snowdrop with faint green markings on the outer petals 'Walrus' is that I never bought, was given, or knowingly acquired it. I did have lots of 'Virid-Apice'. Now I have hardly any. The only double I had/ have is 'Desdemona'. Now I have lots of the not-'Walrus'. Is a mystery. Good thing the plants know who they are. Our driveway was plowed, overnight temperatures in the teens - good thing my husband parked his car at the bottom of the driveway Saturday night because I have not a clue when mine will leave the garage. Perhaps next spring. Judy on the shady side of the street where the trees are etched with snow
