Yellow Peas

I just LOVE yellow split-pea soup and I'd like to grow our own crop. It's proving very difficult (thus far, impossible) to find seed for this. Does anyone know anything about yellow peas or where one might get seeds?

I've grown them from the whole yellow peas ordered from Purcell. They grow exactly like any other pea and these (at least the year I ordered them) grew fairly short and did not require any trellis.

My local Indian food store has them for about $1 a pound and they grow great! they also have plentiful lentils, chickpeas, and other dry beans..
