In my garden this plant has survived some of the worst weather Cornwall has ever experienced: three very wet winters with very severe frosts (down to -7C) and some of the wettest, dullest summers on record.

But my two plants have thrived and slowly grown to clusters of seven or eight rosettes. The silvery green leaves are two feet long and each plant is about seven feet wide. A few leaves are brown at the tips, but it's almost unnoticeable.

This seems to be the best species to grow unless you have a huge garden.They have grown very slowly (they are eight years old) and they have not flowered, but I'm not bothered as I don't want any of the rosettes to die. For me, this is a foliage plant only.

Mine are growing tight against garden walls in... read more

Love this plant, the colours of the flowers are like nothing else.
Ventnor Botanic Garden on the Isle of Wight, United Kingdom currently have a growing collection and are currently working with Royal Botanic Garden, Kew to register a national collection of Puya.
They love the Puya so much at Ventnor that they have incorporated the flower shape into their logo.

The copious amount of nectar produced by the flowers is edible and sweet.

Although this is an extremely vicious plant and not recommended for planting close to paths or where anyone is likely to brush past, the flowers are incredible. Nearly 3" long, very heavily waxy and the most unbelievable shade of dark turquoise, they force you to stop and admire them. I rather like the way that the tips of the branching flower spikes are barren and provide perches for pollinating birds in search of nectar within the flowers.

In the UK, a small 8" high, well rooted offset takes about 6 years to reach flowering size. It appears reasonably hardy, but does resent heavy winter rainfall and the leaves can develop pale spotting by the end of winter. The stout flower spikes reach to nearly 5 feet and take about 7 weeks from first appearance to first flowers open... read more

This makes a good silver accent to any warm garden- is OK for xeriscape as well as moister So Cal gardens. But it is very sharp and should only be trimmed/pruned with gloves on (the sharp spines along the curved leaf edges face toward the center of the plant, and once you get hooked, you can only go further to the center to get unhooked, and often get hooked again even closer- watch out!). It can form huge, impenetrable thickets. A Chilean native. Like many Puyas, this plant has beautiful, large exotic looking flowers that just don't seem to go along with the rest of the plant. THis species has upright, compound flowers that look almost like exotic pineapples on stems, with the most unreal color of turquoise-green flowers in them. These unfortunately occur only briefly in April.
