I donnt think scaling will work Phillippe, Usually with me, most of the older scales die over 2 years, and get replaced by new ones formed by the base of the new leaves. The more large leaves produced, the more new scales are produced. It seems that cardiocrinum scales dont have as long an individual life as some lilium scales...
I once thought i was loosing a plant on which all outer scales surrounding the leaf bases had rotted...but i gave it a bit of extra feeding, and in october, it went dormant, leaving a fairly good sized new bulb formed by the new leaf growth..
If you want to do a swap, I have a large cardiocrinum giganteum bulb that I could possibly post to you which should flower next year, and maybe even leave offsets...
