Lilies: Does anyone know how this might happen., 1 by Teamwild

In fall '08 I planted three Tiger Lily (tigrin splendens) bulbs which came up nice last year but were eaten by voles in the fall. This year I was suprised to see a Lily come up in the spot where they were and when it bloomed last week it seems my orange tiger changed into a pink oriental which so far "Famosa" seems to be the closest match. Is it common for voles to plant new bulbs after eating something :-)
