tulip color breaking

Color breaking and other deformities in Trillium have been attributed 
to mycoplasma infection. The Rock Garden Quarterly published an 
article about this several years ago.

As for tulips, some wild tulip species are strikingly marked, and 
this apparently non-viral character has been exploited in the 
breeding of feathered, flamed, striped, and similar commercial 
varieties. However, this doesn't mean that Dutch tulips are safe to 
plant around virus-free lilies, because some plants (including some 
lilies, as was recently noted about L. lancifolium) can harbor virus 
for many years without showing overt symptoms -- the virus can, 
however, be diagnosed with a lab test. Another good reason to grow 
your bulbs from seed!

And no, I can't guarantee my bulbs are virus-free, sorry. My garden 
has some commercial bulbs in it that have been there for many years, 
though the sale bulbs almost all come from the frames, which are a 
little distance away, and I don't have any imported lilies. There 
are, however, very few aphids in the garden or frames, and these are 
the usual vector for plant viruses.
