After the Apollo landings they tried growing seeds in a "soil" sample
and I gather it was successful. There's nothing poisonous in it.
If current theory is right, that might not be true of Martian soil,
which may be highly oxidising.

That's very interesting and encouraging to know that lunar soil is
"growable" in without too much effort. I also read somewhere the
Apollo astronauts took sycamore and other tree seeds with them to the
Moon and back and that they were subsequently germinated and planted
as Moon trees at certain locations around the states.

Thanks for reminding me about that. Looking it up on Google tells me
that there's a lot of interest about them.. Thousands of hits. They were
taken by Stuart Roosa on Apollo 13. Sadly, there seem to be none in the
UK.
Slightly related topic - I wonder if anyone is growing descendants of
the "killer tomatoes" that went up on the LDEF?
