Before we delve into the "money" mystery of this iconic houseplant let's start with the basics. The Money Plant or Jade Plant is one of the most famous and popular of the many succulent Crassula that are used as indoor plants. Very easy to look after with amazing longevity it was somewhat more popular in the past than it is today. The insulting phrase "old fashioned" might be slung around when describing this Crassula, but as with anything, fashions go around. So if you like it, pay no attention to the insults, instead be proud and display your Jade Plant boldly.
Great growth will come from being placed in a position with a great deal of natural sunlight. However the plant will get by in slightly darker places and will even do well in a windowless room (it would obviously need artificial lighting!).
As with most succulents, Jade Plants are tough and adaptable to many situations and a variety of treatments, however they wont last long if you constantly over water. Water well, then wait for the soil to dry out before doing it again. In Winter you want to give enough to keep the soil just barely moist.
