I am thinking of doing this too. Google search will yield a few leads if you search for: plant tissue culture.
Here is one I found: http://www.une.edu.au/agss/hort/horticultural-science.php
Hope this helps.

Plant tissue culture was once called in vitro - occasionally still is. When Googling, try that phrase. There is some stuff out there on in vitro propagation of grasses starting with nodes which sort of feels lake a good place to begin.

Also look for "Micropropagation".

Note that these things need to be grown aseptically.
