"The artist must decide whether the correct botanical information has been conveyed in the the drawing in the best way possible. When and flowers are huddled together they can be repositioned to give a more open design; and leaves lining up with stems can be moved slightly so that the drawing can be clearly understood. It is difficult to know whether to include insect damage and nibbled bits, as well as leaves that have been on the plant all year and look discoloured and weary. When you are illustrating a plant that retains its bare leaves all through the year, such as a , it would be unwise to tidy up the plant and remove the older leaves as this would destroy part of the plant's life history. Leaves with autumnal fruits will not appear as fresh as they would in the spring."
