germinating Veltheimia seeds

Here in Pasadena, CA Veltheimia come up
like weeds if I don't take care to deadhead them all.
Last month I dug up a bunch of babies to grow on for the
BX. They seem to favor shady spots that get some water
.

Here in San Diego county my Veltheimia sprout like weeds. Just sow them on top
f a potting mix covered with grit in Sep. or Oct. Water well from the bottom
nd they are up in less than three weeks. There doesn't seem to be an
nhibitor. Joe

I am growing some Veltheimia seeds on paper towels with a thin cover of
ropagating sand in a sealed container. Was Googling when they should be planted
nto 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
trainer with mesh large enough to pass the sand particles but not the seeds.
he last is important as some seeds leach out inhibitor chemicals. A "freshen
p" every once in a while gets rid of the leached out inhibitor. The leaching
way of the inhibitor is one of the possible reasons given for an explosion of
eed germination outside after heavy rain.

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