Impatients - can be put directly into water and will thrive very very well -
I use them as pond plants and just put them right into the water and in the
water fall itself

To grow another fig tree - scrape the bark on a low laying branch and then
cover it with soil, the next spring when that branch throws out leaves it
will also have rooted itself and you can now cut if off from the main tree
and it will produce fruit in another year or 2

any other not in the books?
