Organic shapes are figures that have a natural look and a flowing, curving appearance. Different from geometric shapes, they are often also referred to as curvilinear or free form shapes, as they can be made of angles, curves or both. Examples are found in leaves, plants, and animals. Moreover, they generally do not have measurements that are uniform or perfect. From a practical standpoint, this makes it much more mathematically complex to calculate measurements such as area and volume. People also often use organic figures in gardening and landscaping. These types of shapes work well for this because their lack of linearity gives a more natural, blended look to the yard or garden. Landscapers can achieve an organic style either by how they design elements like trim, ponds and general layout, or they can get the organic feel with the specific plants they pick.
