This is the largest-flowered of the Chionodoxas, with blooms up to 1 1/2in across in a bright violet blue with white eyes. (Like many blue flowers, 'Gigantea' seems more violet in photos than in real life.) Seeds itself freely to create lovely carpets. Great with early Narcissus, such as 'Tete-a-Tete'. Heirloom, 1878.
