Tillandsia Xerographica is internationally recognized as an endangered species. Due to its restrictive status, growers are generally required to keep a certain number of offsets (pups) for future mother plants. Propagation via offsets only, although quicker than seed production, has been shown to limit genetic variability across the species. Think of it this way, if all Xerographica were propagated by offsets only, every plant would just be a copy of a copy. Out of necessity to increase the number of plants on the farms, many have started the arduous process of growing Xerographica by seeds. Width: 2-4 Inches Height: 1-2 Inches
