Are you the only one propagating and selling it or is it propagated and sold by local nurseries?
And if the second is applicable - how did you get them to do it?
If I'd want to name my white arachnoideum which I consider unique, I'd need enough plants (which seems to be just a matter of a year or so), enough space to grow those plants (which is more of a problem) and a channel to get them to the market. Easiest would be to involve a local nursery for both propagation and sale. But how to start that relationship?
