This is a list of all fictional plants that appear in J. R. R. Tolkien's Middle-earth writings. Under the Species heading, only those that differ from real-world plants are included.
In Quenya, an Elven tongue devised by Tolkien, the general term for plants, as distinct from animals (kelvar), is olvar.
A kind of shrub that grew around the hill of Amon Rûdh in Beleriand, described in the Narn i Hîn Húrin as "long-legged", sweet-smelling and creating gloomy "aisles" beneath the roof of branches.Christopher Tolkien stated that aeglos was "like furze (gorse), but larger, and with white flowers"; he also compared it with the yellow-flowered gorse bushes said in The Lord of the Rings to have grown in Ithilien. The name, shared by the spear of Gil-galad, means 'snow-thorn' in Sindarin.
The name alfirin, apparently meaning 'immortal' in Sindarin, was used by Tolkien twice. In The Lord of the Rings, Legolas sang about "the golden bells ... of mallos and alfirin" that grew in the land of Lebennin in Gondor; while in the story of Cirion and Eorl it is stated that "the white flowers of alfirin" bloomed upon the mound of Elendil on Amon Anwar.Christopher Tolkien surmised that in the second case the flower should be equated with the simbelmynë, which was also white-coloured and never-fading, and that in Legolas's song the reference is to a different plant.
The end of the line where zero's the sign
A hole in the mind, deaf, dumb and blind
Nothing to cry not even an eye
Zero again the end of no end
A vacant space lacks a familiar face
An unknown face finds a vacant space
The memory killed by a hole soon filled
Zero again there remain no remains
