Hepatica disease

[Gerry Webster]

I get this damage every year on a few leaves of outdoor H. transylvanica. Curiously, an adjacent plant of H. x media  is never affected. I see it more rarely on plants under glass. I've always assumed it is caused some sap-sucking insect. Since the damage is never serious or extensive  I tend to ignore it.

I think this is not environmental. I try to spray the plants with Mospilan. Perhaps it help them.

Thank you for Your answer and help.

I've a colony of Hepatica nobilis self-seeding in a glazed sink.  The leaves on many of the plants have a curious mottled look.  Do you think they may have a virus?

Gail,

Have you checked the underneath of the leaves for thrip or mites?  Looks possible that it could be that sort of damage?  If not signs of insects under the leaves, try a an application of trace elements in case it is a deficiency?  Well those are my, uninformed, thoughts anyway.

Thanks Paul - there is no obvious sign of pests (although my husband seems to have pinched my lens again so only checked by eye).  I'll give a good feed and see if that makes a difference.

Check for scale on the stems as well.... I had similar-ish appearance on some of my seedlings when I got a scale infestation.  It was worse looking than that though.  Hopefully others here who grow more of them than I do will have some ideas.
