Tissue culture is away to produce new plants from small pieces of plants, its 
done in a laboratory and the plants are started off on an agar medium.

When Daylilies were first tissue cultured a method called callus initiation 
was used, this worked out well to produce thousands of plants quickly, but it 
all so produced off types because cells changed once in while in the callus.

Currently, good respectable labs propagate from shot tips and for the most 
part (99%) the plants should be the same as any vegitily propagated plant.  
But once TC got a bad name, many growers wanted to keep the prices high, so 
the story still goes around that all TC plants are bad.  With proper 
procedure and growing out of the product with culling-one can have good 
confidence that you are getting the proper plant.

Lots of plants are tissue cultured, almost all Ferns, Hosta, Heuchera plus 
thousands of others in clouding many trees.
