After observing how well Crocus tommasinianus survived in a lawn area, despite my garden's plethora of bulb-eating rodents, I decided to plant extra corms of other crocuses in the same area and am pleased to see them returning several years in a row. I was also surprised to find seedling C. pulchellus (a fall bloomer) in rough pasture grass near the bulb frames. Therefore, I suggest that if people are having trouble keeping crocuses going in the garden, they plant them in grass -- as long as they can bear to mow the grass fairly high in spring to allow the crocus foliage to ripen. I think the tough grass roots deter burrowing voles, and the grass itself conceals the emerging shoots of the crocuses, which I believe are what catches the attention of deer mice and squirrels; at least, I don't see rodents digging up crocuses which have their leaves fully extended. I also have some very long-lived crocuses which either plunge to great depths (C. ochroleucus) or apparently have settled in between rocks. Jane McGary Northwestern Oregon, USA
