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
Saxifragaceae, Geraniaceae, Arisaema, Cape bulbs, Paeonia, Salvias, Irids
and anything else that is beautiful
