After a bit of research, it appears the ideal way to divide the cardiocrinum gigantium is after the plant flowers. Specifically, the "mother" bulb will flower between 3-8 years after planting (seeds are reported to take 7 years, bulbs typically about half that). The amazing flower stalk should be cut as soon as the flowers are spent (before seeds set) so the plant's energy goes into the growth of bulblets surrounding the dying "mother" bulb. These new bulbs can then be separated from the "mother" bulb. I plan to wait until after the plant's leaves deteriorate in late fall (Pacific Northwest/Seattle area) to do this. Reports suggest a woodland setting is ideal, with a large planting area amended with rich humous. Plant the bulb(s) with the pointed end just poking above the soil's surface. Finally, protect from slugs. After a few more years, more fantastic fragrant giant himalayan lilies should grace your garden. Sincerely, Todd Todd R.
