PERENNIALS

A perennial is a plant that lives for more than two years and persists for many growing seasons. 

Perennial seeds are those that can remain dormant in the soil for a long time and then germinate when the conditions are right. The germination of perennial seeds depends on many factors, such as temperature, moisture, light and nutrients.

The time taken for perennial seeds to germinate varies from species to species. Some take a few weeks or months while others need up to 2 years. Not all seeds germinate at the same time and most species DO NOT have a 100% germination rate. Some species need to be chilled, scarified or soaked in water in order to germinate. 

Some perennials flower the first year while others flower the following year and every year after that. Patience is the key to growing perennials from seed, however it is a great choice for gardeners who don't want the hassle of having to replant every year. Perennials are also more resistant to pests and diseases because they have an established root system that helps them survive through the winter months. 

In cultivation, some perennials that bloom most vigorously in their first year are treated as annuals or biennials and are uprooted after flowering. Tender perennials may also be grown for a season, then discarded in autumn where not hardy. Herbaceous, or soft-stemmed perennials die back to ground level each autumn, then become dormant before producing new shoots in spring. 

The top growth of many perennials dies down in autumn; the roots, safely insulated below ground, store food in order to permit rapid growth when favorable conditions return. Woody (largely trees and shrubs), deciduous plants protect themselves by shedding their leaves, the parts most vulnerable to winter cold, in autumn; their buds remain dormant until triggered into growth by increasing warmth and light in spring. Many hardy evergreens produce small leaves with a reduced surface area, which is often leathery or covered with an insulating layer of hairs to minimize the drying effects of strong winds. 

These plants often root deeply to levels where the soil will not freeze. They may also adopt a ground hugging habit or produce aromatic oils that help to conserve water and act in a similar way to antifreeze.
