Crocus February 2012

[ronm]

I gave a talk this morning to a local gardening group and during the presentation I mentioned virus in Crocuses and later on viruses in Irises. I thought nothing about it until at the end of the talk I  was asked if the same virus attacked both Crocus and Iris, and I didn't know  . Its something I've gone along with and never thought to ask. Can one genus infect the other?

Ron, there are a lot of different viruses which can attack plants. And quite a few of them attack multiple genuses!

Take a look here: http://www.agls.uidaho.edu/ebi/vdie/sppindex.htm. It shows some known virusses with the respective susceptible host species.

Cheers Wim.

Some virus are selective, some attach very wide spectrum of plants. Such are for example Tobacco Rattle virus. It attacks all kinds of bulbs and other perrennials and weeds, too.Sometimes just weeds are source of infection of bulbs.

Just seen the nice photos of C.rujanensis, posted by Jon Evans on the AGS site, presented to the JRGC by the Director, RGB Kew. Nice timing.

Thanks Ron.... I was looking in the Joint Rock Section .

Puzzled that elsewhere in the Forum it was reported that the Jopint Rock had no plants put up yesterday... but that must only have referred to galanthus.

Crocus vernus

A gift from Gert Jan van der Kolk who selected this form.

Wow very nice!

Gerry

I think that is a very nice form of ssp heufellianus or as some would say Crocus heufellianus

[Gerry Webster]

Tony - I'm following Brian Mathew who regards C.vernus subsp. vernus as a single, very  variable entity.

So he does, how sensible

Gerry, the links you put me onto regarding C.pelistericus, from AGS bulletins proved most informative. Thank you.
