aves ofsimilar size. Plant texture can be felt as well as seen. One good way to study texture is by closing your eyes and feeling the plants. The leaves,branches ,bark and buds,of various plants all feel distinctly different. Some are smooth,some prickly,some downright thorny。 each sensation is apart of the plant’s textural character. The farther one stands form a plant,the finer its texture will appear. For that reason,the distance of view must be considered during the textural study of planting design. Color Color results from light peration,absorption,and reflection. Light rays of variable lengths enter a plant leaf to be either absorbed or reflected. If all light rays are absorbed,none are reflected back to the surface。 the result is the absence of coloror black. If all rays are refiected back to surface, the rays are a mixture of different color rays,which results in a color hue. Light rays produce red,orange,yellow,green,bulue,and violet colors. Blends of these color rays produce all of the primary,secondary,and tertiary hues we see. Intenseity is a meansurement of the quality of the basic color in the blend. Bright greens,for example,are said to be intense. Another measurement of light reflection produces a dark color。 a color。 a larger amount of light reflection produces a lighter shade. Plants with a dark bluegreen foliage reflect large amounts of light. The foliage of most plants is dominated by the green hue, meaning that green light rays are reflected in the largest quantity. Plant foliage colors range from blackgreen(grayish),to bluegreen,to the bri。
