Dear Anita and all,
	Yes,,, and no.
	Most of the L squamigera grown in the world are propagated 
vegetatively - not by chip budding or scaling or quartering etc - as 
far as I know. Do you have some specifics otherwise.? The bulbs are 
vigorous enough and multiply fast enough to produce more than ample 
bulblets and divisions to fill the commercial needs.

	Some other Lycoris are tissue cultured - right Tony ?

	L. squamigera was long believed, based on morphology and 
chromosomes, to be a natural hybrid of L. straminea and L. sprengeri. 
That specific cross was purposely repeated and the resulting plant 
looked in all points like typical L. squamigera, but the plants were 
diploid with 2n = 19.  Essentially all cultivated L. squamigera are 
3n = 27.  One problem with this theory is that L. straminea is also 
believed to be of hybrid origin.

	Ocassionally L. squamigera will produce a seed in my garden, 
but there are a variety of other species around that could act as 
pollinators. I think it is safe to say it is totally self sterile.

	Tricky stuff here.
