Puya weberiana

Puya weberiana, or Weber's puya, is a rare and spectacular bromeliad native to the arid mountains of Argentina. Its flowering is impressive: it takes the form of a huge spike filled with pink bracts and tiny blue flowers, emerging from a rosette of silvery green-gray. Drought-resistant but sensitive to heavy frosts, it is an ideal ornamental plant for dry or Mediterranean gardens. Its uniqueness will be fully expressed in a rockery or a mineral setting. In cooler regions, grow it in a pot that you will store away in winter.

Puya weberiana belongs to the Bromeliaceae family. This botanical species grows in the rocky Andean meadows at high altitudes, notably in the provinces of Salta and Tucumán, Argentina. It is a perennial plant without stems, slow-growing. It forms a rosette of leaves that usually measures between 60 cm and 1 m in all directions. The narrow leaves are green on top and silvery underneath, with small reddish hooked teeth along the edges. This foliage persists in winter. What makes this plant particularly impressive is its inflorescence that can reach up to 2.5 m in height. Like other Puyas, flowering occurs in summer on mature plants several years old. The inflorescence features many bright pink woolly-looking floral bracts, stacked on top of each other. The flowers themselves are small, tubular, ranging from mauve-blue to pink, highly nectariferous. The bracts remain decorative for several months, earning this plant the nickname "desert lantern". This Puya's hardiness is estimated at -6°C in well-draining soil. The plant often perpetuates itself through the development of daughter rosettes that grow near the base.

Puya weberiana is a collector's plant to showcase in a rockery or gravel garden in mild climates, especially on the Mediterranean coast. To accompany it, consider, for example, Yuccas, Dasylirions, Phormiums, and Nolina nelsonii. This unusual plant will make a big impact on a terrace, in a cactus soil mix, where it will stand out in a large pot. At the first signs of cold weather, store it away, handling it with care due to its thorns, in a greenhouse or conservatory.
