unknown plant, any ideas?

I planted some cardamom seeds then got really excited when one started shooting up. However after looking on google images i can see that it doesn't look like a cardamom plant. any ideas what it is?

 

Welcome to Gardeners Corner

Afraid its a Fat Hen Plant. You can eat the leaves as spinage though.

 

Thanks. i thought i was being optimistic about the cardamom!

 

I expect someone will be along to tell you how to grow one soon

 

Hmm!
Elettaria cardamomum is a tropical plant. I very much doubt if you will ever get a plant to a sufficiently big size to produce flowers, which need to be fertilized to give the typical seeds.
Advice here.
