Diversity of plants image version 5.png
Plants are a major group of life forms and include familiar organisms such as trees, herbs, shrubs, grasses, vines, ferns, mosses, and green algae. About 350,000 species of plants, defined as seed plants, bryophytes, ferns and fern allies, are estimated to exist currently. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering and 15,000 bryophytes. Green plants, sometimes called metaphytes, obtain most of their energy from sunlight via a process called photosynthesis.

Aristotle divided all living things between plants (which generally do not move), and animals (which often are mobile to catch their food). In Linnaeus' system, these became the Kingdoms Vegetabilia (later Metaphyta or Plantae) and Animalia (also called Metazoa). Since then, it has become clear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts, both technical and popular. Indeed, an attempt to perfectly match "plant" with a single taxon is problematic, because for most people the term plant is only vaguely related to the phylogenic concepts on which modern taxonomy and systematics are based.

Primula scotica
The flora of Scotland is an assemblage of native plant species including over 1,600 vascular plants, more than 1,500 lichens and nearly 1,000 bryophytes. The total number of vascular species is low by world standard but lichens and bryophytes are abundant and the latter form a population of global importance. Various populations of rare fern exist, although the impact of 19th century collectors threatened the existence of several species. The flora is generally typical of the north west European part of the Palearctic ecozone and prominent features of the Scottish flora include boreal Caledonian forest (much reduced from its natural extent), heather moorland and coastal machair. There are a variety of important trees species and specimens; a Douglas Fir near Inverness is the tallest tree in the United Kingdom and the Fortingall Yew may be the oldest tree in Europe. The Shetland Mouse-ear and Scottish Primrose (pictured) are endemic flowering plants and there are a variety of endemic mosses and lichens. Conservation of the natural environment is well developed and various organisations play an important role in the stewardship of the country's flora. Numerous references to the country's flora appear in folklore, song and poetry.

Persicaria capitata (Pink Knotweed, Japanese Knotweed or Pink bubble persicaria) is an ornamental plant of the genus Persicaria in the family Polygonaceae. The spikes are 5–10 millimetres (0.2–0.4 in) long and 5–7 mm (0.20–0.28 in) in diameter. P. capitata is a prostrate herb, native of Asia, and naturalised in parts of Australia.
