Anyone heard of Chinese parsley? I don't mean cilantro or coriander; it tastes like parsley with a pepper bite

Question

Seed for this herb used to be available through Vermont Bean or Johnny's but was discontinued and they never answered my inquiry. The stem was ribbed, the leaves similar to flat leaf parsley, but it had a pronounced black pepper bite. It was great in chicken or turkey soup.

Answer 1

I grow it and order from Richters
www.richters.com
They send to USA, Canada, UK, Japan, Ausralia and more.
This is an excellent site to order herb seeds from, fast delivery, great service, safe site too

Answer 2

It may have been what is more commonly referred to as Chinese Celery (see picture here: http://chinesefood.about.com/library/blphotocelery.htm) that sounds more like what you describe.
