crypt seed?

[loopylee]

My crytocoryne usteriana throw up a flower every so often. so far none have set seed so im wondering if anyone has ever managed to get any crypts to seed?

They would need to be artificially polinated, if you scroll down on this excellent Crypocoryne page theres a couple of paragraphs about polination that will be of interest to you.
