Puya alpestris ssp. zoellneri

Puya is a large genus, with over 150 species, in the bromeliad family (Bromeliaceae). Plants in the family are all from the New World, ranging from the southern parts of the U.S. all the way down to southern South America. The family probably originated in South America, where its diversity is greatest. Of the cultivated types, a large portion are tropical plants not suitable for garden use in our more temperate climate. Puyas are an exception to this. Their distribution is mostly in a north-south band following the Andes mountain range, and many can withstand frost. While puyas grow in dry areas, their leaves are not succulent. However, their drought-tolerance, spiky form, and sharp-toothed leaf margins combine to make them appealing to succulent growers, and they are often used with succulents in garden plantings. Puya berteroniana, which comes from Chile, is a large species, forming a multi-headed clump which may be over 5 feet (1½ meters) tall. Its spiny-edged sword-like leaves are green on the upper surface and silvery on the underside, reaching about 3 feet (1 meter) in length. P. berteroniana belongs to a small group of 7 species (classified as sub-genus Puya within the genus Puya) which have a unique type of inflorescence. Members of this group have stout flower stalks with lateral branches, each of which has flowers along its lower portion, but ends in a stiff spur which is often used as a perch by birds. Plants of P. berteroniana are quite dramatic in and of themselves, but their flowers are unforgettable. The inflorescence is typically 8 to 12 feet tall (2½ to 4 meters), with many side-branches. The lower part of each branch is densely packed with large flowers of an incredible metallic blue-green color, which contrasts strikingly with the orange pollen. Flowering time is in spring.

Large terrestrial bromeliad; stiff leaves with fragile teeth; giant blue bloom stalks

This spectacular xeric terrestrial bromeliad comes from the subalpine screes and rock fells of central Chile. Large, mounding rosettes of steely silvery leaves (each to 2' or wider) are armed with savage, inward pointing spines that may trap anything that falls into the rosette. On large plants, spectacular steely blue flowers, the color of which really looks 'wrong' for anything found in nature, appear in quantity on person-height, stout stalks. These persist for a several months and are a magnet for hummingbirds. One of the hardiest Puyas, it will appreciate excellent drainage on gritty, gravelly soil and overhead cover from winter rains if possible. It can also be grown in a pot. Under xeric conditions, it should be able to survive down to at least 15 °F.

One of the most astonishingly beautiful plants to grace our planet direct from Chile! Spectacular, 2-3’ long & 1’ across pineapple-y shaped spikes are densely studded with 1.5” waxy, metallic blooms of the most unearthly emerald-turquoise. Contrasted by bright orange stamens & filled with blue syrupy nectar, they’re a bonanza for birdies who perch on sterile, horizontal stems. To 6-10’ tall in bloom (year 6-8). Spreading slowly by offshoots, spiny 3’ silvery rosettes work well as a security barrier. Can be grown in a container! Totally deer proof, plant in well-drained soil with occasional Summer water. Hardy to 20°F.
