That's a Silver Squill (Ledebouria socialis), Scotsgran. It's often sold in the cactus and succulent sections of the garden centers here. Unlike other squills, it doesn't take much frost, but it is evergreen. Probably best as a sunny houseplant, or an indoor-outdoor plant sheltered from the rain in Scotland.

Thank you she will be thrilled to know what it is. She lives in Forres in Morayshire so they do get snow but generally the climate is better than in more exposed areas. She may well have had it in the house or green house.

Indeed, mine is now some size with many offsets clustered tightly together. It is an indoor plant as Tug says, at least mine is! Ok outside in summer though.

My friend had this outside until it got a bitcold and then put it in a leanto greenhouse but she was worried when they got frost that it might die so she brought it indoors to the front porch. She sends her thanks for such a speedy reply.

Plants such as this often tolerate cold (relatively cold conditions) if kept perfectly dry. Still best not getting below 0 though.
