Broadleaf Species
Broadleaf species are in its simplest form have thin broad leaves, compared to t needle like or scale like leaves that Conifers have. Taxonomically they are in the angiosperms or flowering plants division. Examples species, include, Oaks, Ashes, Elms, Privets, etc.
Compared to Conifers their evolution goes back only to between 140-100 million years. They became the dominant species of plants about 100-60 million years ago, with anywhere between 250,000-400,000 species, depending on who you read.
Broadleaf reproduce with flowers that are evolutionary more diverse and sophisticated than Conifer reproductive devices Cones. Flowers have adapted to allow pollination from a host of agents including wind, water, incest's, birds and animals.
Broadleaf embryos are formed in protective coating the endosperm, that provide the embryo, with food and protection from the elements. The endosperm form a major source of food to many insects, birds and animals including humans, who in-tern have all helped with the flowering plants wide dispersal and indeed domination.
As Bonsai they form one of the most versatile groups. With whole range of seasonal interest, from spring foliage, to flowers, to innumerable leaf shapes, sizes, textures and colours, with most many deciduous species their is also the added season attraction of a trees fine branches in winter. |
