RE: Romneya coulteri propagation


I take it that we are to soak the seed in gasoline for ten
minutes and then let 'em dry off. Reading the instructions cursorily,
perhaps some readers would be tempted to set fire to the whole lot,
gasoline and all.  <8)

I remember getting some seed of (I think) Anigozanthus from Australia
years ago and it came with instructions to put the seed in a dish and
cover with some dried leaves or a few bits of paper. One was then
supposed to ignite this cover, which would apparently provide just
enough but not too much heat to start germination..

I have to admit I neve got round to trying it though, so don't know how
well it would have worked.
