Houseplants can bring cheer to a room.
Houseplants - Houseplants 1
It is a source of frustration to many home-owners (and a source of great annoyance to commercial growers) that most people expect a bunch of flowers to last a week but a houseplant to last forever! A rule of thumb is this: a flowering plant will have a limited period of life but a foliage plant will last much longer.
With care you might get a well-budded cyclamen to last several weeks but if you want to adopt a plant that will become part of your family then go for a crassula - with care it will last longer than you do!

Most gardeners believe that hippeastrum and amaryllis are one and the same thing but plant experts disagree
