Family

Bromeliaceae

Botanical Name

NEOREGELIA concentrica

Plant Common Name

Concentric Bromeliad, Concentric Neoregelia

General Description

A large epiphytic bromeliad from tropical forests of Brazil, Neoregelia concentrica is grown for its lush evergreen rosettes that flush deep purple at their centers.

Concentric bromeliad produces broad rosettes of waxy, yellow- to medium-green, strap-shaped leaves. The leaves are edged with spiny black teeth and are often flecked or blotched with purple. The leaf bases at the center of the rosette form a tubular cup which catches and holds water. Mature rosettes bear tiny white or lavender blooms on a pincushion-like head that nestles within the "water cup." The leaf bases turn violet or fuchsia shades as the flower head develops, with the coloration persisting for months. Rosettes die after flowering, producing offsets (pups) to take their place.

This tropical tree-dweller loves humidity, warmth, and a moist, well-drained growing medium. Secure it to a tree branch in a tropical garden or greenhouse, or grow it in a porous soil or potting mix that's rich in organic matter (such as sphagnum or pelleted bark). Keep the rosette "cup" filled with water from spring to fall, especially if plants are exposed to direct sun rays. Water sparingly from late fall through winter. This bromeliad makes a nice border accent or massed groundcover for frost-free gardens.

Named selections of concentric bromeliad include 'Plutonis', whose leaves are blotched and flushed with deep maroon.
