Perennials—especially small flowering plants—that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several years in their natural tropical/subtropical habitat but are grown as annuals in temperate regions because their above-ground biomass doesn't survive the winter.


Perennial plants are most commonly herbaceous (plants that have leaves and stems that die to the ground at the end of the growing season and which show only primary growth) or woody (plants with persistent above grounds stems that survive from one growing season to the next, with primary and secondary growth, or growth in width protected by an outer cortex),Perennials typically grow structures that allow them to adapt to living from one year to the next through a form of vegetative reproduction rather than seeding. These structures include bulbs, tubers, woody crowns, rhizomes and turions. They might have specialized stems or crowns that allow them to survive periods of dormancy over cold or dry seasons during the year. Annuals, by contrast, produce seeds to continue the species as a new generation. At the same time, the growing season is suitable, and the seeds survive over the cold or dry period to begin growth when the conditions are again suitable.

The meristem of perennial plants communicates with the hormones produced due to environmental situations (i.e., seasons), reproduction, and stage of development to begin and halt the ability to grow or flower. There is also a distinction between the ability to grow and the actual task of growth. For example, most trees regain the ability to grow during winter but do not initiate physical growth until the spring and summer months. The start of dormancy can be seen in perennials plants through withering flowers, loss of leaves on trees, and halting of reproduction in both flowering and budding plants.Each type of plant must be separated differently; for example, plants with fibrous root systems like daylilies, Siberian iris or grasses can be pried apart with two garden forks inserted back to back, or cut by knives. However, plants such as bearded irises have a root system of rhizomes; these root systems should be planted with the top of the rhizome just above ground level, with leaves from the following year showing. The point of dividing perennials is to increase the amount of a single breed of plant in your garden. (Source: en.wikipedia.org)
