Scilla madeirensis is exotic in every way -- starting with the bulbs, which are dark purple! They are similar in size and shape to an amaryllis bulb. Its 6 inch long raceme has dozens of bluish blooms held horizontally from the stem- like a big, blue bottlebrush. This is a choice ornamental bulb that unfortunately is endangered in the wild.
