Description
Tillandsia Sabre (achyrostachys x exserta) is a striking xeric hybrid that combines the structural rigidity of T. achyrostachys with the elegant, recurved aesthetic of T. exserta. This cross results in a plant that is highly sought after for its sculptural form and silvery appearance. It’s name, T. saber comes from it’s bloom spike which is one long non branching inflorescence that is bright red.
Morphology and Appearance
-
Foliage: The plant typically features a rosette of stiff, channeled leaves. Thanks to the exserta parentage, the leaves often exhibit a graceful “curly” or recurved habit as they mature. The foliage is heavily covered in trichomes, giving it a velvet-like, silvery-grey or frosted appearance.
-
Size: It generally matures into a medium-to-large air plant. Depending on the specific clone, it can reach a diameter of 10–14 inches.
-
Inflorescence: When in bloom, the plant produces a tall, robust floral spike. The stalk is usually branched (a trait from exserta) but retains the thicker, more substantial bracts characteristic of achyrostachys.
-
Flowers: The bracts often blush with shades of pink or soft orange. The tubular flowers are typically a pale yellow or greenish-cream, though some specimens may lean toward a bicolorous or lavender hue depending on the specific genetics of the exserta parent used.
Growth Habit and Care
This hybrid is exceptionally hardy and well-suited for environments with high light and lower humidity.
-
Light: It thrives in bright, filtered light. In more humid climates, it can handle significant direct morning sun, which helps tighten the rosette and enhance the silver coloration.
-
Watering: As a xeric species, it prefers to dry out quickly. A thorough soaking or heavy misting 1–2 times a week is usually sufficient, provided there is excellent air circulation.
-
Airflow: High airflow is critical. Because of the recurved leaves and dense trichomes, moisture can sometimes trap at the base; ensuring it dries within a few hours of watering is key to preventing rot.
Aesthetic Value
In the horticultural trade, this hybrid is often favored for its “wild” yet symmetrical look. It is particularly effective when mounted on natural media like cork bark or cholla wood, where its recurved leaves can drape naturally. Unlike the more delicate T. exserta, the infusion of achyrostachys DNA gives the plant a sturdier feel, making it slightly more resilient to handling and shipping.
