So I gotta grow indigo...

[P-Naughty]

The thread title says it all. I am a student in a upperdivision college history class and we have a class project of installing a traditional four-square garden at the university botanical garden complete with a solar powered fountain in the center and limestone paved paths. While we will be purchasing some full grown plants for placement, each student was given a pack of a certain type of seed (Mayan indigo, yellow wild indigo, blue "false" indigo, and regular indigo [Indigofera Tinctoria]) to plant... on their own... in little cups... in college dorms...

So anyway, what I need is some advice. It can be just simple advice on soil moisture all the way up to technical stuff specific to indigo.

So far I have followed the directions given to me by my professor on how to get them started. I'm just looking for any special directions any gardeners could provide about care once it starts growing or how to get it growing.
