I germinated Veltheimia capensis seed (from Silverhill) in my
peatmoss/perlite mix in 6/04 after sowing 2/04 in the greenhouse. Bloom
was 12/10.

*posted on behalf of Ina Crossley*

I am growing some Veltheimia seeds on paper towels with a thin cover of
propagating sand in a sealed container. Was Googling when they should be
planted
into soil and came across this bit:

The reason for using moist sand instead of moist paper are
1) the sand colour changes when drying out
2) the root of the sprouted seed is not easily damaged when removed from
sand.
3) the sand doesn't decompose.
4) the seeds are easily separated from the sand by using a kitchen wire
strainer
with mesh large enough to pass the sand particles but not the seeds. The
last is
important as some seeds leach out inhibitor chemicals. A "freshen up"
every once
in a while gets rid of the leached out inhibitor. The leaching away of
the
inhibitor is one of the possible reasons given for an explosion of seed
germination outside after heavy rain.

I am particularly interested in the inhibitor thing. What is known about
it? Is
this a general concern when growing seed? Any particular seed which is
affected
by it?
