Treescanalsobedividedintodeciduousand coniferous categories.
Deciduous trees are plants that drop their leaves every year, usually during periods of dryness or cold weather. Their branches remain free of foliage until conditions improve. For the tree, this means that it can save energy by not working to keep the leaves green and healthy.
Trees lose their leaves when they go dormant, which is a means of self-preservation. The majority of plants require sun, light, and water to survive, and when any one of these elements is lacking, the stress triggers hormonal changes. These changes prompt the tree to put more energy into simply surviving.
Coniferous trees keep their leaves and then shed only the oldest leaves.
Conifers are the trees of the coldest regions. Only conifers are found north of about latitude 55 degrees. Conifers are fast growing trees that have adapted to a variety of environmental conditions.
Coniferous trees can be small bushes or one-hundred meter high redwoods.
Coniferous trees grow up instead of out and are of a triangular shape. The leaves can be long needles, or small, flat scales. Seeds grow in cones. There are three major groups of conifers – firs, spruces and pines – and they can be identified by their needles.

Garden Types of Plants
Annuals
Annuals are plants that live for a year or less based on Latin “annus”, meaning “year”. Annuals are also known as seasonal flowering plants which flower only for three to four months. They are normally grown through seeds. They grow, flower, make more seeds and die, within a year. Annuals are great for creating instant effect and adding color to your garden. Planting annuals also gives you the option of changing the layout of your garden after a year. Most annuals are tender and some of them like phlox look beautiful and are excellent as borders and hedges.
Biennials
A plant that takes two years to grow from seed to fruit is a biennial, based on Latin “biennis” meaning “two years”. These are also seasonal flowering plants that flower only in the second year of planting. To have blooms year after year with biennial flowers, you have to plant seeds every year.
Perennials
The Latin “perennis” means ‘many years'. Perennials are those flowering plants that last longer and keep on flowering. Most take two years until they are old enough to bloom. Once you plant them there is no need for replanting year after year. But they are not a good option, if you want to change the layout of the garden frequently. Most perennials grow best in slightly acidic soils and prefer six to eight hours of sun per day. Watering should be deep, infrequent and applied directly to the soil. This type of watering will promote deep rooting and will help reduce leaf diseases.
