I grow a great many Fritillaria species, mostly under cover but a couple of dozen in the open garden, and I've never had anything eat the bulbs, although my former garden was plagued by voles. The leaves, however, are sometimes attacked by slugs, and the flowering stems for several years were mostly destroyed by deer and rabbits. The latter got into the frames, which were ventilated enough that they could hop in even over a fairly high foundation. I even caught a couple of them one day. Now I have moved to a location with no voles, deer, or rabbits, and the bulb house is critter-proof to a high degree. As a result, the flowers have come back wonderfully. It snowed 2 inches here today and the temperature is not predicted to exceed 50 degrees F for the next week. Nonetheless, everything in the bulb house (where snow blew in through the hardware cloth sides) looks quite content, though the crocuses don't open in these temperatures, and in the open garden only a few larger daffodils got knocked over. Cyclamen coum is flowering brightly through the melting snow. Jane McGary Portland, Oregon, USA
