I've grown Ornithogalum more than 30 years and have not found it weedy. It first came to me as " Ghost flower". It does seed mildly but just around the perimeter of the clumps. I find its green seed capsules lovely. O umbellatum I've inadvertently had even longer in various gardens. It is virtually indistructable. As Jim mentioned none of the plants are fertile ( as in most Galanthus nivalis in the trade and in old gardens ). Its worst feature is that it makes gazillions of small offsets so that when the ground is cultivated they can spread quite efficiently.
