Hi Carrie,
This picture is of a flowering size plant.
It flowers quite easily for me, outside in this shaded position. It is still in its pot, with gravel around it. The Bromilliads probably keep the humidity up... as they're filled with water, while the 13m high tree they're all sitting under keeps the ground quite dry most of the time... I couldn't grow lawn there, which prompted the garden, so it isn't ever, by any means, considered soggy. It's also well protected down under there as evidenced by the Terrantula leg fern growing so well next to it.
As far as I know, they really do not seem to grow big... I think they're miniature plants.... they do grow into a clump though... and the clump can get as big as you want to grow it. I have it in flowering size in a 4 inch pot inside, as a specimen plant. I bought it as a species plant, so I think it's also pink, but I haven't managed to flower it yet to be sure.
