People purchase flowers and plants as gifts and for their own enjoyment. This growing business niche should be considered like any other retail business with a perishable product line. There are two ways to become an owner of a floral shop. You could start one from the ground up and build the business. The other way is find one that is for sale and make the purchase. There are valid reasons to go either way. The big plus for buying an existing business is they have a following from an existing customer base. This fact will mean an immediate cash flow to the new owner. A purchase of an existing business will cost far more than starting one from scratch. This is the basic reason to start from scratch.
