Scaevola is a genus of flowering plants in the Goodeniafamily, Goodeniaceae. It consists of more than 130 tropical species, with the center of diversity being Australia and Polynesia.
Common names for Scaevola species include scaevolas, fan-flowers, half-flowers, and naupaka, the plants' Hawaiian name. The flowers are shaped as if they have been cut in half. Consequently, the generic name means "left-handed" in Latin. Many legends have been told to explain the formation of the naupaka's unique half flowers. In one version a woman tears the flower in half after a quarrel with her lover. The gods, angered, turn all naupaka flowers into half flowers and the two lovers remained separated while the man is destined to search in vain for another whole flower.
Scaevola is the only Goodeniaceae genus that is widespread outside of Australia. In at least six separate dispersals, about 40 species have spread throughout the Pacific Basin, with a few reaching the tropical coasts of the Atlantic and Indian Oceans.
The Hawaiian Islands are home to ten Scaevola species, nine of which are endemic. Eight of the indigenous species are the result of a single colonization event. Scaevola glabra and Scaevola taccada arrived separately to produce a total of three colonizations of Hawaii by Scaevola. Some of the endemic species are of hybrid origin.
Beach naupaka (Scaevola taccada synonym S. sericea) occurs throughout the Pacific and Indian Oceans and is considered an invasive species in Florida, USA, and in some islands of the Caribbean including the Cayman Islands and the Bahamas. Beachberry or Inkberry (Scaevola plumieri) is widespread along the Atlantic coast of the tropical Americas and Africa; however, it is becoming rarer in areas where S. taccada is displacing native coastal plants.
Most Australian Scaevola have dry fruits and sprawling, herbaceous to shrubby habits. By contrast, nearly all species outside Australia have shrub habits with fleshy fruit making dispersal by frugivores easy.

Joint doctors Purple Ryder cannabis seeds – Available as Regular seeds only
Purple Ryder is a beautifully coloured new auto-flowering variety developed by underground breeder Mossy. The Joint doctors Purple Ryder (AKA Purple JEMS) buds display a broad colour palette, ending with a stunning royal purple. Purple Ryder plants produce large purple nuggets covered in a sticky layer of resin. The reward is a well-balanced stone that satisfies the palate and relaxes the body. Flavour is on the floral side with a hint of sweetness. Low ambient odour!
Passing directly from the seedling to the flowering stage, Purple Ryder altogether does away with the vegetative growth stage, in a process called autoflowering. In other words, when planted, it sprouts, grows a couple sets of leaves, then immediately and automatically begins flowering (males at about day 17, females at day 20). As a result, it is the quickest, most compact, and most discrete plant available.
