FFF23 - FLORAL SNAILS

Vigna caracalla is a leguminous vine from the family Fabaceae, originating in tropical South America and Central America. The species is named "caracalla", fromt eh Latin for "hood or cloak", referring to the hooded shape of the open flowers. Some people suggest that this specific meaning comes from Caracas in Venezuela, but this is probably a misapprehension.

This perennial vine has fragrant flowers reminiscent of hyacinths. The buds, especially have a distinctive curled shape, giving rise to the common names "corkscrew vine", "snail vine", "snail creeper", or "snail bean". This vine is hardy in zones 9 and above, liking full sun and consistently damp soil. It prefers high heat and humidity and can become invasive if these conditions are met. In colder zones, it does well in a pot if it is overwintered inside.

FFF22 - CALLA LILY

Zantedeschia is a genus of herbaceous flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The name of the genus was given as a tribute to Italian botanist Giovanni Zantedeschi (1773–1846) by the German botanist Kurt Sprengel (1766–1833). Common names include arum lily for Z. aethiopica, calla, and calla lily for Z. elliottiana and Z. rehmannii although it is neither a true lily (Liliaceae), nor Arum or Calla (related genera in Araceae). It is also often erroneously spelled as "cala lily".

It has often been used in many paintings, and is visible in many of Diego Rivera's works of art (see The Flower Vendor, amongst others). The Zantedeschias are rhizomatous herbaceous perennial plants growing to 1-2.5 m tall with leaves 15–45 cm long. The inflorescence is a showy white, yellow or pink spathe shaped like a funnel with a yellow, central, finger-like spadix. The Zantedeschia species are poisonous due to the presence of calcium oxalate. All parts of the plant are toxic, and produce irritation and swelling of the mouth and throat, acute vomiting and diarrhoea. However, in some countries the leaves are sometimes cooked and eaten after suitable preparation.

FFF21 - CAPE DAISIES

Osteospermum is a genus belonging to the Calenduleae, one of the smaller tribes of the sunflower family (Asteraceae). Osteospermum used to belong to the genus Dimorphotheca, but only the annual species remain in that genus; the perennials belong to Osteospermum.

The scientific name is derived from the Greek osteon (bone) and Latin spermum (seed). It has been given several common names: African Daisy, South African Daisy, Cape Daisy and Blue-eyed Daisy. There are about 50 species, native to Africa, 35 species in southern Africa, and southwestern Arabia. They are half-hardy perennials or subshrubs. Therefore they do not survive outdoor wintry conditions, but there is still a wide range of hardiness.

Most widely sold cultivars are grown as annuals and are mainly hybrids of O. jucundum, O. ecklonis and O. grandiflorum and can be hardy to -2°C. If hardy, they can be grown as perennials or as shrubs. The photo is of a relatively newly introduced cultivar known as "Tradewinds Pure Yellow". They flower repeatedly and produce beautiful waves of colour during the growing season. This is a patented variety that was introduced in 2006 and the flowers are sterile and will not set seed.

FFF20 - PRECIOUS BULBS

The tulip is a perennial, bulbous plant with showy flowers in the genus Tulipa, which comprises 109 species and belongs to the family Liliaceae. The genus's native range extends from as far west as Southern Europe, North Africa, Anatolia, and Iran to the Northwest of China. The tulip's centre of diversity is in the Pamir, Hindu Kush, and Tien Shan mountains. A number of species and many hybrid cultivars are grown in gardens, as potted plants, or to display as fresh-cut flowers. Most cultivars of tulip are derived from Tulipa gesneriana.

Tulip mania or tulipomania (Dutch names include: tulpenmanie, tulpomanie, tulpenwoede, tulpengekte and bollengekte) was a period in the Dutch Golden Age during which contract prices for bulbs of the recently introduced tulip reached extraordinarily high levels and then suddenly collapsed. At the peak of tulip mania, in February 1637, some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman. It is generally considered the first recorded speculative bubble (or economic bubble). The term "tulip mania" is now often used metaphorically to refer to any large economic bubble (when asset prices deviate from intrinsic values).

A very Happy Easter to all who celebrate it, Happy Pesach to our Jewish friends, and Happy Palm Sunday for the Eastern Church Christians!
