After patiently waiting for an entire decade, plant enthusiasts are being rewarded with a spectacular sight – the extraordinary blooming of the ‘Sapphire Tower’ plant. This incredibly rare species has unfurled its vibrant teal-blue blossoms at the Birmingham Botanical Gardens ¹, putting on a show that is truly out of this world.
The Sapphire Tower, scientifically known as Puya alpestris, is a bromeliad native to the harsh, high-altitude slopes of the Chilean Andes. Its common name perfectly captures the alien-like beauty of the towering inflorescence that emerges once every 10 years or so.
A Decade of Anticipation Pays Off
Witnessing these fleeting blooms is a privilege that few will experience. The Sapphire Tower’s flowering cycle is excruciatingly slow, with the plant spending years storing energy before producing the iconic spire of metallic blue flowers.
An Evolutionary Marvel
Beyond its rarity, the Sapphire Tower represents an evolutionary marvel – a living relic that has remained largely unchanged for millions of years. Its incredible adaptations, like the ability to store water in thick, succulent leaves, have allowed it to thrive in the barren, high-altitude environments of its native Chile.

Moreover, the plant’s striking coloration serves a vital purpose. Those brilliant blue-green hues attract hummingbirds and other pollinators, ensuring the continuation of this ancient species.
At the Birmingham gardens, dedicated horticulturists have stepped in to manually pollinate the short-lived blossoms.
A Race Against Time
Visitors have a limited window to witness the Sapphire Tower’s splendor. The delicate flowers typically last no more than two weeks before withering away. Once the blooming concludes, the rosette that produced the inflorescence will die, though side rosettes may eventually bloom years down the line.
While photos and descriptions can provide a glimpse into the extraordinary beauty of the ‘Sapphire Tower’ plant, there is no substitute for experiencing it in person. The Birmingham Botanical Gardens has opened a special viewing area for this ephemeral bloom, allowing visitors to marvel at the towering inflorescence up close before it withers away until the next decade.
For those within traveling distance, this is a rare opportunity to witness a true living relic that has remained virtually unchanged for millions of years. Make plans to visit soon and be transported by the unearthly, sapphire-hued blossoms of the Puya alpestris – a fleeting spectacle that will leave an indelible impression and reinforce the wonders of our natural world.
