Description

Arisaema speciosum is one of those plants that seems to have slithered straight out of a Victorian explorer’s sketchbook—exotic, mysterious and just a touch theatrical. Commonly known as the showy cobra lily, it rises from the soil with an elegant poise, displaying a solitary, three-part leaf that frames its true spectacle: a striking purple spathe hooded over a pale, white-tipped spadix, like a cobra about to strike. The markings are extraordinary—striped and mottled in tones of burgundy and cream—making Arisaema speciosum a captivating centrepiece for shaded borders, woodland gardens or any spot that deserves a bit of drama.

Despite its exotic appearance, Arisaema speciosum is surprisingly accommodating. It’s content in moist, humus-rich soil with dappled shade, where it adds a tropical air without demanding tropical conditions. Emerging in late spring and flowering through summer, Arisaema speciosum brings structure and intrigue long before other perennials wake up to the idea. The tuber quietly retreats underground in winter, resting before returning with equal flair the following year. Partner it with ferns or hostas for a striking contrast in texture and tone—or let it stand alone, where its sinuous form can be properly admired. There’s nothing ordinary about Arisaema speciosum—it’s a botanical conversation starter that manages to be both refined and a little bit wild.

Arisaema speciosum is called showy cobra lily because its hooded flower resembles a rearing cobra poised to strike—dramatic and exotic in equal measure.
