Tillandsia xerographica aka Giant Tillandsia

Tillandsia xerographica is an evergreen air plant in the bromeliad family. Its native range runs from southern Mexico into Central America. It grows in dry tropical areas with wet and dry seasons. In the wild, it lives on high branches of trees. This growth habit makes it an epiphyte. Gardeners grow it indoors and outdoors in mild climates.

The plant forms a rounded clump of curled leaves. Garden plants reach about 1–3 feet [0.3–0.9 metres] tall and wide. RHS gives an upper size of 3.3 feet [1 metre]. Growth is slow, with maturity taking five to ten years. Each leathery leaf has a broad base and a narrow tip. The leaves curl back and spiral into a tight rosette. Their pale green and silver-grey tones provide year-round interest. The stems are smooth and have no scent.

The plant flowers once in its life, when conditions suit it. Its branched flower spike rises 1–3 feet [0.3–0.9 metres]. RHS describes shorter spikes, reaching 1.3 feet [0.4 metres]. The bracts provide much of the colour around the flowers. These can be green, yellow, or orange-red, with rosy leafy bracts. The small, tubular flowers range from red to purple. The flower display can last for months. Plants also form offsets, which growers can separate for new plants. Wait until each offset reaches one-third of its parent's size. Seed offers another way to raise plants.

Grow this air plant without compost, fixed to a support. It needs bright, filtered light and good airflow. Both sources favour filtered light in their care guidance. Their watering schedules differ, so the setting matters. RHS calls for twice-weekly rainwater baths from spring through autumn. NC State suggests soaking every week or two, less in winter. Heat and dry indoor air may increase its water needs. Drain it well after soaking and let it dry upside down. This helps prevent crown rot. It tolerates drought but cannot cope with frost.

Use it as a houseplant, container accent, or hanging display. It can spend summer outdoors in a shaded, sheltered spot. Bring it indoors when the weather cools. RHS rates it H1C; NC State lists USDA zones 9–11. It needs no pruning and has few disease problems. Aphids and mealybugs may still attack it.
