Gardeners' Notes:

I already grew puya alpestris then started some seedlings of this so called P. Berteroniana . The alpestris has thinner leaves and more controlled growth. While the berteronianas took off like crazy and have become HUGE. They now have several big multiple heads. They have wider leaves, and bigger thorns ( armature) . A word of warning......give them plenty of room. Most puyas are as drought hardy as cactus. I hardly ever water mine except when I see a flower spike starting. While my alpestris blooms regularly every 2-3 years none of my berteroniana have even considered it. They are under 10 years old .Don't know how many years it will take. But I expect the bloom spikes will be 6 ft. tall ( alpestris spikes are much shorter) and have the same beautiful flowers as alpestri... read more

In 2013, (Zizka et al, 2013) it was shown that what has been called Puya berteroniana in the past is actually referrable to a population of Puya alpestris (which they name, Puya alpestris ssp zoellneri); "true" Puya berteroniana is probably of hybrid origin and is only known from the original collection.

I saw this plant on EBAY and the seeds go for big money. I obtained seeds from TradeWindsFruit for 2.00 including shipping. First time I had no luck and am on my second try.

Is one of the largest genera in the pineapple family. From central Chile. Bears huge 6'-10' flowering spikes up to 20 at a time, metallic, deep bluish green flowers with vivid orange stamens in Summer. Silvery foliage has recurved, hooked spines along edges and makes large striking 3' clumps, rosettes die after blooming and offsets carry on. Slow growing, enjoys very dry, well drained soil. Is hardy to 20F. Is very well suited to our Coastal climate.
