(I posted this earlier but I made a mess of it so here it is again).
This is an aechmea that I grew from seed. At first I thought it was an A. gamosepala but now I'm not so sure. Aechmea1 was when it was flowering and the white fluffy stuff on the flower stem can be seen, and Aechmea2 was after it had set seed. The green seed pods are white and the ripe seed pods are purple. Each seed pod contains at least 100 tiny seeds.
