Heheh...yeah it crossed my mind for a second that someone might think you
were supposed to light it all on fire but dismissed it. Don't set it on
fire, just soak and wash them off. :) My friend had asked an English
nurseryman (who had flats and flats of Romneya seedlings), and learned the
method. When he got home he ordered a big lot of Romneya seed and when they
came he put it in the gasoline and went out for a second while they soaked.
About an hour later he remembered...ran back in in a panic and washed them
off. They all came up.
