I found Bromies to be just the ticket for places where digging out spaces for large rootballs was not doable.Your Bromie choices depend on what sun exposures you have there. Neoregelias are plentiful and quite varied for bright shade and a few can go full sun.
Aechmeas enjoy full sun if you don't mind the serrated edges.
Aechmea blanchetiana:
Vresias, cryptanthus, guzmanias- they all have their place. Just research what light each needs and purchase the correct species and varieties for your conditions.
I had lots of Bromie patches when I lived in Broward.
Most came from Tropicana's "From the Loading Dock" section or local plant shows where I could buy in bulk on the cheap.
I've included a link to Tropiflora- they are in Sarasota and I am sure they come to a plant show near you a couple of times a year.

Here is an enormous Neo grown in full sun and 48" across- don't need too many of them to fill a space!
