The act of sending flowers should take into account the nature of the occasion but should also reflect the giver and the receiver to be more personal and seen as special attention and not just a stereotyped gift. That means knowing something about their preferences. A florist in there area might know what sort of foliage they like if you don't know.
You wouldn't want to send live flowers to someone who cannot have them, so for get well occasions, always call the hospital and ask what is and is not allowed. Even at home, some patients can't have live flowers and plants, but there are other options your florists can provide such as well made artificial flowers or even flower art in crystal or other media.
As a nice touch, it is good to have the flower delivery in a special container such as a vase, basket or planter, so that the gift will last longer than the cut flowers. Many people believe that a live plant is a more appropriate gift for someone who is ill or older, since it implies that they will enjoy a longer life. A low maintenance plant is the best choice for a gift for someone who is sick.
You can personally arrange for flower delivery by stopping by a local florist who knows what you want, or by calling the florist on the phone. However, you can now order flowers online to be delivered almost anywhere in the world. You may want to start with the web site of your favorite florist, using their delivery network. You may also decide to look for online flower delivery on your own.
When you arrange for flower delivery, an important tip is giving the provider good information about when the person is likely to be home or at the place you are having the floral gift delivered. If it is to a hospital, have the alternate home address available and make sure they will check for discharge before making a futile attempt.
Local availability can vary, so it is important to realize that if your floral order is delivered to another area it might not be identical to what you picked out. The local florist will do their best to create a floral arrangement as close to the original flowers as possible. However, it might not be exactly the same.
