Have you ever happened to receive one of those plant compositions in a small pot, with all the plants perfectly blooming all together? They are usually very attractive so people buy them, very often spending a lot of money, and thinking it is better to make this kind of gift instead of cut flowers, because plants will live for a long time. They do live longer than cut flowers (usually) but in most cases they die immediately after they stop blooming. They are grown in nurseries and assembled to be pretty on shelves for the time buyers bring them home. They are forced to bloom and clumped up in small pots almost without any growing media.
Such was the composition I received. After a while the composition was brown and dead.
