Re: [IGSROBIN] G argenteum

Hi there Ingrid,

Long time, no speak.  However, I can help you with this one.

I've grown G. argenteum for some years and it is not easy to keep here.  I
grow it in a raised bed, covered in the winter against the wet/cold
combination which seems to cause it to rot off.  However, even then I find
that a plant only keeps for two to three years.  However, the plant seeds
copiously and most germinate.  I had a plant which I lost winter, which
left around a dozen seedling this spring.  Overall, it seems to act rather
like an annual species!

It does hybridise fairly freely with other G. cinereum group species,
particularly G. cinereum cinereum, producing a range of attractive hybrids.
 The species itself is very beautiful.

I saw Mimi's comments about x lindavicum 'Purpureum' and 'Alanah'.  I am
still not totally certain that these are the same plants, although they may
be synonyms i.e. that are indistuingishable, but not clones.  There is no
certain information that I have been able to trace to show that the
Sündermann and Gore-Booth plants are the same, although they were clearly
very similar.
Best Regards,
David Victor
