Several pots of this mysterious autumn-flowering Narcissus viridiflorus with murky green spidery flowers grace the Mountains display in the Alpine House.
The skinny scapes can be topped with one to five flowers, each with six reflexed narrow petals in this strange blue-green colour. The three stigma shine in a protective cup like golden nuggets. It is reputedly highly-scented but there was no discernible trace when this photo was taken!
Narcissus viridiflorus, in the Amaryllidaceae family, is native to parts of Spain and North Africa.
