Hi,Does anyone have advice regarding propagating Crinumasiaticum?
There is a very large one (5’ high and around) growingnearby in a minimally tended right of way between a sidewalk and a street. Itreceives filtered sunlight and is irrigated naturally by rain.  This year, there has been a lot of that.  I believe C. asiaticum is supposed to be onlyhardy in Zone 9 locations, typically Florida, however this one has prosperedfor at least 25 years in an 8B location in se N. Carolina.

Bulbils have begun to form on the flowering heads. At what pointcan the bulbils be removed to be individually propagated? Is there a specific physicalappearance that identifies them as ready to be detached?   Should each bulbil be placed on the surfaceof the potting medium or submerged below the surface? Should the bulbil bescarified at all?  What light conditionsare beneficial to germination, full sun or filtered light?

Thanks in advance for any suggestions/assistance.

Edward
