Spindly growth occurs when one plant receives a great amount of sunlight, while the other would develop as a deformed one, due to lack of sunlight and other natural resources needed for photosynthesis.
Securigera varia (synonym Coronilla varia), commonly known as crownvetch [2] or purple crown vetch, is a low-growing legume vine. It is native to Africa, Asia and Europe and is commonly used throughout the United States and Canada for erosion control, roadside planting and soil rehabilitation.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

Often the entire seed stem, or even the entire plant will come out of the ground if the seeds catch on clothing or fur, aiding seed dispersion. During the plant's first year of growth it has only a basal rosette of foliage, [7] with the flowering stalk ascending the second year. The leaves are dark green and irregularly shaped.
Vinca difformis in habitat, Cáceres, Spain. Vinca plants are subshrubs or herbaceous, and have slender trailing stems 1–2 m (3 + 1 ⁄ 2 – 6 + 1 ⁄ 2 ft) long but not growing more than 20–70 cm (8– 27 + 1 ⁄ 2 in) above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely.
Vinca minor (common names lesser periwinkle [1] or dwarf periwinkle) is a species of flowering plant in the dogbane family, native to central and southern Europe. Other vernacular names used in cultivation include small periwinkle , common periwinkle , and sometimes in the United States, myrtle or creeping myrtle .
Partially shelled popcorn seed saved for planting. In agriculture and gardening, seed saving (sometimes known as brown bagging) [1] is the practice of saving seeds or other reproductive material (e.g. tubers, scions, cuttings) from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees. [2]
Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma , either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination , so pollinizer trees are planted in orchards.
