This is beautiful plant was known as a variety of T. brachycaulos but is now i think believed to be a species in its own right. Tillandsia multiflora syn. T. brachycaulos var. multiflora.
It colors up very well with more pastel shades than the species. It then, as the name 'multiflora' suggests, produces many purple tubular flowers.
Its an easy species to grow with medium to high light levels and regular misting with good air-movement.
Here is a lovely large flowering size specimen mounted on drift wood with added Spanish Moss'.
