Billbergia nutans

San Marcos Growers at: http://www.smgrowers.com/index.asp   Had this to say about Billbergia nutans

"Billbergia nutans (Queen's Tears) - A vigorous bromeliad that is easy to grow and will readily form clumps of upright bronzy-green rosettes. The 2 feet tall rosettes hold one foot long, slender leaves that have small teeth along the margins. Arching flower stalks carry pink bracts and flowers that have chartreuse green petals edged with royal-blue. Plant in shade in a well drained organic rich soil and water occasionally - for an epiphytic bromeliad this plant is surprisingly drought tolerant and can often be found surviving in abandoned gardens. It is reliably hardy to 30-32 degrees F but able to tolerate short duration temperatures much lower - this plant was only slightly damaged in our historic 1990 freeze at 18 degrees F. This plant is native to Brazil, Uruguay, and Argentina where it grows both as an epiphyte in low trees and terrestrial on the forest floor from 2,300 to 3,000 feet elevation. Though often commonly called "Queens Tear's" for the ornate hanging flowers, another common name is "Friendship Plant" which is attributed to this plant multiplying readily and propagating so easily that it is often passed between friends."
