A green leaf is green because of the presence of a pigment known as chlorophyll, which is inside an organelle called a chloroplast. When abundant in the leaf's cells, as during the growing season, the chlorophyll's green color dominates and masks out the colors of any other pigments that may be present in the leaf. Thus, the leaves of summer ...
These maps show a scale, or index of greenness, based on several factors: the number and type of plants, leafiness, and plant health. Where foliage is dense and plants are growing quickly, the index is high, represented in dark green. Regions with sparse vegetation and a low vegetation index are shown in tan.
Variegation is the appearance of differently coloured zones in the foliage, flowers, and sometimes the stems and fruit of plants, granting a speckled, striped, or patchy appearance. The colors of the patches themselves vary from a slightly lighter shade of the natural coloration to yellow, to white, or other colors entirely such as red and pink ...
In botany, an evergreen is a plant which has foliage that remains green and functional throughout the year. [1] This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season. Consisting of many different species, the unique feature of evergreen plants lends itself to various environments and purposes.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

It is a slow-growing tree which may reach 35 m (115 ft) tall [5] with a trunk up to 1 m (3 ft 3 in) in diameter. [citation needed] The bark is dark red-brown.The leaves are scale-like, 2–4 mm (0.079–0.157 in) long, blunt tipped (obtuse), green above, and green below with a white stomatal band at the base of each scale-leaf.
This is the time in which deciduous trees begin the process of colorful changes in their foliage. In New England, a large percentage of trees produce a pigment known as an Anthocyanin , which results in brilliant reds and purples commonly seen around this time; a change that is particularly pronounced in the region's sugar maple trees.
