Hi Yong,
I think it is aechmea aquilega.
Cheers Fran

I agree with Fran

Another vote for A. aquilega.

Thank all comment.

I think i got mislebeled seeds from seed bank or seed donator misunderstood.

At first glance, I think its flower look very different from both Ae.emmerichiae or mulfordii. Both have more branch inflorescence. My aquilega still not flower yet. Now I know my plant is A.aquilega.

Cheers
Yong

I was at a friend's house and he had lots of plants that he called Ae rubens, but the strange thing was that they all had seed pods full of seeds. Either he has a pollinator or he doesn't have rubens. Do any of the rubens look-alikes self readily?
