Ranunculus Sceleratus

This hybrid creation hails from an extreme of Victorian beauty but is weirdly like no other garden flower in the world. Harry Cipriani’s fall planting for spring was a smashing success at his Palermo house where it has languished since 1903.The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup Ranunculus repens, which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup Ranunculus bulbosus and the much taller meadow buttercup Ranunculus acris. In ornamental gardens, all three are often regarded as weeds.

Ranunculus

Molecular investigation of the genus has revealed that Ranunculus is not monophyletic with respect to a number of other recognized genera in the family—e.g. Ceratocephala, Halerpestes, Hamadryas, Laccopetalum, Myosurus, Oxygraphis, Paroxygraphis and Trautvetteria. A proposal to split Ranunculus into several genera has thus been published in a new classification for the tribe Ranunculeae.All Ranunculus (buttercup) species are poisonous when eaten fresh, but their acrid taste and the blistering of the mouth caused by their poison means they are usually left uneaten. Poisoning in livestock can occur where buttercups are abundant in overgrazed fields where little other edible plant growth is left, and the animals eat them out of desperation. Symptoms of poisoning include bloody diarrhea, excessive salivation, colic, and severe blistering of the mouth, mucous membranes and gastrointestinal tract. When Ranunculus plants are handled, naturally occurring ranunculin is broken down to form protoanemonin, which is known to cause contact dermatitis in humans and care should therefore be exercised in extensive handling of the plants.

Hardiness Zone: Ranunculus corms are winter hardy in growing zones 8-10, where temperatures do not fall below 25°F. Gardeners in these areas plant ranunculus corms in fall for spring flowers. In colder areas (zones 4-7) ranunculus will not survive the winter outdoors unless they are protected by a greenhouse. Gardeners in these areas can plant ranunculus corms in early spring for late summer flowers.

To ensure flawless blossoms, it's important to carefully control air temperatures and well as the amount of light the plants receive. When ranunculus are grown in a greenhouse or under low tunnels, the bulbs are typically planted in fall for flowers in late winter and early spring. (Source:www.longfield-gardens.com)
