Garden bouquet. Slow flowers.

This is what I want a florist to provide when I send flowers to family and friends too far away for me to deliver the bouquets in person –  the large one for a table greeting,  the small, scented one (not needing water:  gets better as it dries) for someone in hospital or otherwise wanting and needing a touchable reminder of the outdoors. 

The mixture of simple garden flowers and grasses and a fern and an herb or two convey what I want to express.  And what I like to receive; as I did yesterday from some very special people.

So far I have not come across a flower shop that provides this service.

I wonder why.  Sending flowers through a florist is not cheap.  I wonder what percentage of the cost is in the actual greenhouse flower and how much a delivery charge. Garden flowers would seem far less expensive and more accessible and worthy of consideration as a commercial endeavor by a florist.  Seems to me a flower seller could fill this niche and make a success of it.  

Sort of in the sense of 'stopping to smell the roses' but not the hot house kind.
