There are many species of Paris besides the familiar British and European native species, P. quadrifolia. The best species are centred on China and the Himalayas, with the exceptional, white flowered, P. japonica being found only in Japan.
In the garden they require a deep, fertile, humus-rich yet well-drained soil in light shade. They also need a great degree of patience, as they frequently sulk when transplanted. They frequently miss a season above ground, while they make roots but exceptionally they can take 3-4 years before they make sturdy foliage and flowers on a regular basis.
During establishment the gardener is their greatest threat, as digging them up to see 'why' is a sure way to set them back even further.
Ordering is possible from Autumn and Spring lists. Paris are late ripening items.
