Tillandsia Espinosae is a wonderful species from Ecuador and Peru.
This species is stoloniferous, meaning that new pups or vegetative growths are born on runners that stretch out from the parent plant.
This is a very easy species to grow, in high light levels or full sun, with very good air-movement, making sure that water does not sit for too long in the leaf bases which can cause rot. It makes a great looking clump after several years growth.
