Part of a plant’s form is the result of the growth habit of the plant. In some evergreens,for example,the branches overlay one another. The plant’s form takes on an irregular line because of this habit should always be considered to be an element of form. The best way to study plant forms is to visit a park,arboretum,or other area where mature are in plentiful supply. Compare the forms closely to classify specific plants and note the minor differences within classifications. Visit to a nursery are helpful for studying the forms of young or intermediategrowth stages of plants. The silhouette formed by a group of plants is probably the most important contribution of form to landscape position. The form of plants in silhouette must allow for function(shade,screening,wind protection,enclosure,and so on),while providing pleasing lines at the same time. Stems,leaves,bark,and buds are the physical features that determine the texture of a plant. Textures ranging from fine through medium to coarse are visible because of the size and shape of these features and the way light and shadow play off them. Larger leaves,stems,and buds usually create an effect of coarseness. But the number of branches and leaves and the spacing between them also affect the texture. Thick,tight f
