I think it is generally the case that bulbous plants in natural habitats are much less likely to multiply vegetatively than they are in cultivation, perhaps due to increased competition for resources, predation, etc. I recently visited the largest British population of Fritillaria meleagris (millions of plants - see my blog) and it was very evident that the majority of flowering plants were singletons, rather than clumps, and that scapes with two flowers are very rare. In the garden, by contrast, bulbs planted 3 yrs ago, in the lawn, are already forming small clumps and many stems have two flowers. That is one example, but it is rare to see what a gardener would consider to be a 'good clump' of any bulb in the wild and why (for horticultural purposes) it's important to select for clumping as a valuable trait in a seedling population.
