Phlox is a genus of 67 species of perennial and annual plants in the family Polemoniaceae. They are mostly found in North America in diverse habitats. They flower in spring, sometimes in fall or summer. This is a very delicate plant and requires good care for keeping it fresh and living. They are wither white, pink or lavender, trumpet- shaped flowers arranged in an elongated cluster along the length of the stem. Because of its commercial desirability, Garden Phlox has been significantly hybridized to give different coloured blooms.
Permaculturists employ techniques from a broad range of disciplines. These tools are selected and applied according to how well they allow permaculture's principles to be applied.
Greenhouses are building or complexes in which plants are grown. By providing a more controlled convenient environment, they expand the growing possibilities for the crops. Inside a greenhouse, gardeners have control over temperature, humidity, soil aeration, soil moisture and drainage, fertility levels, and light.
Vegetables are classified according to which part of the plant is eaten. Some vegetables fit into more than one category when several different parts of the plant are edible, e.g. both the roots and leaves of beetroot can be eaten.
