For years,it's been assumed that the inside environment limits the variety of plants that people are subjected to.Lately,however,plants that are usually only grown outdoors have found their way into inside spaces.There are a few simple reasons why this is.
The modern inside environment can be a good place for a wide variety of outdoor plants.Plants that ordinarily cannot grow in colder outdoor weather can be protected by the inside spaces,where temperatures are easily controlled.Plants that used to be found only outside,such as trees,have become more and more popular as decorations inside houses.Orchids (兰花),which were once only found in hot places,have begun to grow well in inside places.A large number of smaller plants have also found their way into homes.
One reason that the modern home has made exotic (引进的) outdoor plants more practical is the modern use of windows.In the past windows were used less often in buildings than they are today.It is partly because of the ability of large windows to admit a large quantity of light from the sun and to keep the heat in at the same time,that many outdoor plants have been able to make their move inside.
It is true that most of the plants that have been successful in moving inside have been small.Some of the best-suited varieties are the vines (藤本植物).Many vines that grow in natural locations make excellent decorations where other plants prove difficult to grow.Although some trees can be grown inside,it is not likely the larger varieties can be used.Unfortunately,most homes just don't have the space to grow a monkey tree.
