The little-known South African bulb Ledebouria zebrina sailed through our winter (single digits F) without a scratch and looks great right now. Ledebourias are cousins to the more popular scilla, and this one gives a wonderfully tropical look to the garden. The back of the leaves are striped like a zebra at the base (hence the name). We have not idea how far north this might be winter hardy, but welcome your feedback.
How cool! Do you have a photo of the zebra stripes? Is it possible to get a camera down there? Where is it planted in your garden?
