Fractal Broccoli
Broccoli, a plant of the Cabbage family, Brassicaceae, is a cool-weather crop eaten boiled, steamed, or raw.

Sunflowers (Helianthus annuus) are large flowering plants native to the Americas. They most commonly grow to heights between 1.5 and 3.5 m (5 and 11 ft), although the tallest known sunflower reached 12 m (39 ft) high. The large inflorescence is composed of a flower head (or "composite flower") of numerous florets (small flowers) crowded together. The florets within the sunflower's cluster are arranged in a spiral pattern and will mature into seeds. The seeds are used as snack food, expeller pressed into sunflower oil, made into sunflower butter (a peanut butter alternative), or milled into flour.

Cirsium vulgare is a species of thistle in the plant family Asteraceae. 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.
