The difference that fresh makes

It's probably not a huge surprise that I am enamored of flowers.  I'd be lying if I said that I love all flowers equally.  I'm not trying to knock anyone's appreciation of flowers and it bears saying that nothing beats flowers that you harvest from your own garden or that come from a local flower farmer.  Most flowers that are available for purchase (to consumers or florists) have been harvested at the best stage for longevity in shipping and transport.  This is a careful science and often involves some fairly advanced chemistry.  A huge number of these flowers are grown in countries where labor costs are extremely low (a real mixed bag for the foreign employees - nice to have a job but not so nice that so much of the profit from the industry goes to others) and environmental safety standards are also extremely low.  They can use chemicals on the flowers they wouldn't be able to use here.  Sometimes these flowers are given an extra fumigation to prevent insects from hitching a free ride along with the stems.  The entire picture is kind of impressive from an efficiency and operational standpoint!  
It's not what I'm looking for in a flower at all.  When I grow flowers I take great care with each seedling or bulb.  I don't harvest flowers at the first opportunity because I enjoy how the flower matures.  When I cut flowers to arrange for myself, I like flowers at their most full expression.  When harvested early, they never achieve this size or openness.  Something that I've observed over the years is that many of the flowers I grow actually sparkle in the sun.  A florist friend told me this is a result of the petals being fully hydrated.  Flowers are meant to shimmer!  I've never seen this on a flower at a store.  There is a range of color that petals can't approach when they've been harvested at the first opportunity, held in cold storage for weeks (the case for tulips, narcissus, and peonies), and transported through a variety of means before being available for purchase.  Sure, you can recut the stems and help freshen them up but it doesn't rejuvenate them to the same point a freshly cut mature bloom gets.  The picture above isn't the best from a photography perspective but it shows the sparkle of the tulip petals that I'm talking about.  No filter!  The glow of the petals is honestly how they look. 
As I've grown in my flower farming, I've also grown to appreciate the entire life cycle of the flowers.  I'm not yet to the stage where I harvest seeds (except accidentally in the case of things like Orlaya, celosia, cerinthe, and a few other self sowing wonders) but I have no doubt I'd be doing that if I had more space.  My favorite way to enjoy flowers these days is in the garden.  Cutting them for arrangements is a pleasure too but different than watching them interact with the wind and the bees and the sunlight.  That's part of why I am a very vocal advocate of growing your own.  Not everyone can do that, and I believe it's better to have any flowers than none at all.  If you are able to grow your own Just Do It! If you aren't, the next best thing is to support your most local flower farmer.  You will get the freshest blooms and they will enjoy your support.
