Broccoli, a plant of the Cabbage family, Brassicaceae, is a cool-weather crop eaten boiled, steamed, or raw. The Roman natural history writer, Pliny the Elder, wrote about a vegetable which might have been broccoli and some recognize broccoli in the cookbook of Apicius, but its history is unclear. Broccoli was certainly an Italian vegetable long before it was eaten elsewhere.
The flower of a Blessed milk thistle (Silybum marianum). Originally a native of Southern Europe through to Asia, it is now found throughout the world and considered an invasive weed. Thistles can be toxic to cattle and sheep, but their extract can be used to cure amanita poisoning. A different extract can also be found in Rockstar Energy Drink.

Immature cones of a Colorado Blue Spruce (Picea pungens), a species of spruce native to western North America. It is a medium-sized evergreen tree growing to 25 to 30 metres (82 to 98ft) tall, exceptionally to 46m (151ft) tall, and with a trunk diameter of up to 1.5m (4.9ft). The cones are slender and cylindrical, 6–11 centimetres (2.4–4.3in) long, and are reddish to violet in color, maturing to pale brown 5–7 months after pollination.

Native to Europe and Western Asia, it has become naturalised in North America, Africa and Australia, and is an invasive weed in some areas. It is a ruderal species, able to colonise bare ground, but also persists well on pasture as its thorny leaves and stems make it unpalatable to most grazing animals. The flowers are rich in nectar, attracting bees and butterflies, and the seeds are a favourite with goldfinches, linnets and greenfinches. The downy pappus, which assists in wind dispersal of the seeds, is used by birds as nest-lining material.
