Cauliflower is one of several vegetables in the species Brassica oleracea, in the family Brassicaceae. It is an annual plant that reproduces by seed. Typically, only the head (the white curd) is eaten. The cauliflower head is composed of a white inflorescence meristem. Cauliflower heads resemble those in broccoli, which differs in having flower buds.

Broccoli is an edible green plant in the cabbage family, whose large flowering head is used as a vegetable. The word broccoli comes from the Italian plural of broccolo, which means "the flowering top of a cabbage", and is the diminutive form of brocco, meaning "small nail" or "sprout". Broccoli is often boiled or steamed but may be eaten raw.

Cabbage (Brassica oleracea or variants) is a leafy green biennial, grown as an annual vegetable for its dense-leaved heads. Closely related to other cole crops, such as broccoli, cauliflower and brussels sprouts, it descends from B.  oleracea var. oleracea, a wild field cabbage. Cabbage heads generally range from 1 to 8 pounds (to kg), and can be green, purple and white. Smooth-leafed firm-headed green cabbages are the most common, with smooth-leafed red and crinkle-leafed savoy cabbages of both colors seen more rarely. It is difficult to trace the exact history of cabbage, but it was most likely domesticated somewhere in Europe before 1000 BC. By the Middle Ages it was a prominent part of European cuisine, although savoys were not developed until the 16th century. Cabbage heads are generally picked during the first year of the plants' life cycles, but those intended for seed are allowed to grow a second year, and must be kept separated from other cole crops to prevent cross pollination. Cabbage is prone to several nutrient deficiencies, as well as multiple pests, bacteria and fungal diseases. The Food and Agriculture Organization of the United Nations (FAO) reports that world production of cabbage and other brassicas (these plants are combined by the FAO for reporting purposes) for calendar year 2010 was almost 58,000,000 metric tons . Almost half were grown in China. Cabbages are prepared in many different ways for eating, although pickling, in dishes such as sauerkraut, is the most popular. Cabbage is a good source of beta-carotene, vitamin C and fiber. Cabbage when contaminated is sometimes a source of food-borne illness in humans.

Rubus laciniatus, commonly called evergreen blackberry or cutleaf blackberry, is a species of blackberry that is native to Eurasia. It has been introduced to Australia and North America, and become a weed and highly invasive species in forested habitats in the United States and Canada, it is very difficult to control. Evergreen blackberry is a deciduous shrub that grows up to 3 meters tall with prickly shoots. The flowers are in clusters, the petals are pink or white. The fruits are shiny and black, similar to the common blackberry, with a unique and fruitier taste. The fruits are not true berries in the botanical sense. [Wikipedia]

The blackberry is an edible fruit produced by many species in the genus Rubus in the family Rosaceae. Blackberry is a perennial plant that grows to 3-6 meter tall. The pale pink flowers are produced in late spring and early summer. The fruits are rich in vitamin C, anthocyanins, flavonols and ellagitannins (PMID: 22082199), they have shown the beneficial effects to human health (PMID: 22082199)
