Pamianthe peruviana, the giant Peruvian daffodil, is an epiphytic Amaryllidaceae species from seasonally dry areas of Peru and Bolivia, now believed extinct in the wild. Grow it in a well-aerated mix, never waterlogged, in moderately bright, humid warmth.

About
Pamianthe peruviana, also known as the giant Peruvian daffodil, is a species of epiphytic plant native to seasonally dry areas of Peru and Bolivia, but is believed to be extinct in the wild.
How to grow it
Despite it being very rare in cultivation, it can be easily cultivated as a houseplant if kept in a well aerated substrate, because it is intolerant of waterlogged conditions, which rapidly induce root rot. Ideally, it should be cultivated under moderately bright, humid conditions at temperatures of 18-30 °C. Seeds can be sown all year round. The optimal time is March–August. The remaining months are less optimal. The germination temperature should not be below 20 °C. Pamianthe makes a good greenhouse or container display. It is also suitable as a long-lasting cut flower.
Where it grows
It was found along streams in the warm to temperate northern region of Peru at elevations of 1800 m above sea level.
