About 6 years ago, I had a seedling do the exact
same thing. Someone back then - told me it was a 'Mosaic Virus of sorts'
which results in almost teardrop-like markings. I was told that it's
not common, and usually occurs only on white, Lavender, blue, and purple
iris flowers. Below is a photo of my virus stricken seedling.
The virus can 1.) originate in the seed; 2.)
can be picked it up in the soil; and also 3.) transmitted to the plant
by aphids. (.....and it's hard to be certain exactly how it occurs for each
I was given instructions to dig up and soak
the rhizomes in bleach water for a good half hour,...... then replant it
(when dry) in a different location all together, and eventually the virus would
go away. The virus DID eventually go away, but it took about 2 years to do
I found this short listing online (see below) of
Mosaic Viruses (at this link):
|"Iris, Bulbous and
Rhizomatous -- Viruses |
Cause: Iris mild mosaic virus
(IMMV) and Iris severe mosaic virus (ISMV) are problems for bulbous
iris; Iris fulva mosaic virus (IFMV) is a problem for rhizomatous
irises. All are in the potyvirus group. Transmission, by aphids, is
nonpersistent. Bean yellow mosaic virus (BYMV) and Narcissus
latent virus (NLV) have also been found. Less commonly found are
Cucumber mosaic virus, Broad bean wilt virus, and Tobacco
ringspot virus. "
I'm sure there are other scientific
reports/information that can be found online as well. I hope this info
helped. And....... on another
