DESKTOP 2499 - JONQUIL

Narcissus jonquilla (Jonquil, Rush daffodil) is a bulbous flowering plant, a species of Narcissus (daffodil) that is native to southwestern Europe and northern Africa, but has naturalised throughout Europe and the United States. It bears long, narrow, rush-like leaves (hence the name "jonquil", Spanish junquillo, from the Latin juncus = "rush"). It is in the Amaryllidaceae family of plants. In Spring it bears heads of up to 5 scented yellow or white flowers. It is a parent of numerous varieties within Division 7 of the horticultural classification. Division 7 in the Royal Horticultural Society classification of Narcissus includes N. jonquilla and N. apodanthus hybrids and cultivars that show clear characteristics of those two species.

N. jonquilla has been cultivated since the 18th century in France as the strongest of the Narcissus species used in Narcissus Oil, a component of many modern perfumes. Like other members of their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia.

DESKTOP 2485 - HELLEBORE

Commonly known as hellebores, members of the Eurasian genus Helleborus comprise approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. The scientific name Helleborus derives from the Greek name for H. orientalis "helleboros"; "elein" to injure and "bora" food, referring to the fact that many species are poisonous. Despite names such as "Winter Rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae).

DESKTOP 2386 - CALLA HEART

Zantedeschia aethiopica (known as calla lily and arum lily) is a species in the family Araceae, native to southern Africa in Lesotho, South Africa, and Swaziland. It is a rhizomatous herbaceous perennial plant, evergreen where rainfall and temperatures are adequate, deciduous where there is a dry season. Its preferred habitat is in streams and ponds or on the banks. In some countries (e.g. New Zealand) it may be considered an introduced weed.

It grows to 0.6–1 m tall, with large clumps of broad, arrow shaped dark green leaves up to 45 cm long. The Inflorescences are large and are produced in spring, summer and autumn, with a pure white spathe up to 25 cm and a yellow spadix up to 90 mm long. Z. aethiopica contains calcium oxalate, and ingestion of the raw plant may cause a severe burning sensation and swelling of lips, tongue, and throat; stomach pain and diarrhoea may occur.
