Annual, any plant that completes its life cycle in a single growing season. The term is usually applied to herbaceous flowering plants in which the dormant seed is the only part of an annual that survives from one growing season to the next. A growing se
Perennial, any plant that persists for several years, usually with new herbaceous growth from a part that survives from growing season to growing season. Trees and shrubs, including all gymnosperms (cone-bearing plants), are perennials, as are some herba
In northern countries only few wild plants flower in November, but the gradually drying stems of the chicory plant persist even in cold winters. The piercing blue flowers appear from late spring right through to late autumn and the strong, deep perennial roots and the flat leaf rosettes protect...
Rhizome plants such as potatoes gather energy in the form of starch or other sugars (glucose, sucrose, and fructose), and these rhizomes are thicker compared to stems growing above the ground. Rhizomes also protect perennial plants by providing them with energy throughout winter. ...
The living root system can be gained with the help of perennial plant systems. But many farmers focus on annual crops due to which there are no living roots in the soil. This aspect reduces the fertility and nutrients of the soil. It is a good option to grow perennial crops again to ma...
Most flowering plant species reproduce primarily by outcrossing, including the great majority of trees, shrubs, and perennial herbs. Adaptations that prevent self-fertilization include self-incompatibility (genetic recognition and blocking of self-pollen) and dioecy (separate male and female individuals)....
