(till-land' see-ah)

Common name: Tillandsia, Air Plant, varies with species

Family: Bromeliaceae, Bromeliad

Height x width: 6-24" x 6-24" (generally 12" x 12")

Growth rate: moderate

Foliage: variable, generally gray from silvery-gray scales (which absorb moisture and nutrients), some species green; scaly leaves strap-shaped, narrow triangular or linear; usually in rosettes

Flowers: tubular to funnel-shaped, 3 sepals and 3 petals often with spreading lobes, opening in day, surrounded by colorful bracts; solitary or more often in 2 rows forming a spike, or in a compound inflorescence; flower scape often with colorful bracts; may last several months; grandis blooms after 35 years

Light: full sun to bright, may not bloom if insufficient light

Temperature: cool to warm (when active growth)

Watering: moderate

Fertility: low (moderate for green species)

Humidity: humid

Soil: green--epiphytic, gray--attached to slabs, rocks or similar objects and surfaces

Pests and Problems: fungal root rot (green species), mealybugs, scales

Growth habit, uses: green--pots, gray--epiphytic supports; variable, exotic growth habits

Other interest: native to tropical and subtropical Americas; named after 17th century Swedish botanist Elias Tillands; many native habitats have been decimated by over-collecting, ensure plants purchased are nursery-grown

Other culture: relatively easy if proper environment, good air circulation is essential

Propagation: offsets, 7 years to flowering from seed
