Of course, what they mean when you see Fritillaria rubra is the common red flowering form of Fritillaria imperialis. (There is no Fritillaria rubra recognized in botany.) My experience is inconclusive with the bulb. I can tell you it will not keep moles away, as I had one tunnel almost directly above a Fritillaria imperialis bulb, without deviation in its path, and continue on. But moles are not herbivores. They eat insects, worms and such ((bit not plants). Never had a gopher or vole problem to test with.
Orientpets will certainly grow stems larger than a half inch. While plants in the dicot group have a tendency to be constricted at first, they often grow around the wired and will continue to grow. But lilies are monocots with a different kind of internal stem structure, and I don't think they would be as forgiving as the dicots.
