Dear John et al,

Many plants have evolved to require special conditions to bloom, set seed, and especially to sprout the seeds.  Smoke exposure techniques were developed, I believe, in Australia a number of years ago due to the fact that many outback plant seeds were reluctant to sprout under normal circumstances.  I found that Billardiera seeds if not fresh will grow with this method.  It is a standard practice to treat seeds of Proteas this way.

A good site that explains fire and smoke requirements for some north American plants is at  http://nativeplants.for.uidaho.edu/Content/…
