From the Himalayan Mountains. Requires mulch for protection in colder areas. These are an extra LARGE selection of Speciosum, also known as the Himalayan Giant. They have a slightly more open spathe than the regular Speciosum. These Tubers are at least the size of a softball. Healthy Full Size Bulbs. Best handled and transported during the cold season.
