One of the things that bothers me about the cut flower industry is how, over the past couple of decades, we have become conditioned to buy what is most convenient for the large scale producers and importers.
90% of the flowers available to buy in the supermarket or florist shop conform to the size which will fit easily into a standard florist package box - smallish head, long straight stem. This cuts costs right down all along the production line from mechanised growing, spraying and harvesting to a certain number of boxes fitting onto a pallet or into a refrigerated van.
What has been lost is a sense of different scales - whether that is eight feet tall plume poppies or miniature astrantia - if it doesn't fit into the system you are unlikely to be able to get it. The most convenient is rarely also the most appropriate or attractive.
One of the flowers shops that I have come across via Amy Stewart's site is the Bonny Doon Garden Company which addresses this, producing a range of posies - many of which fit into a teacup like the one in the photo. I think that these are an ideal solution for those occasions when you want to send flowers - say to celebrate the birth of a baby - but know that the recipient will be inundated with flowers. An arrangement like this - our one is an an elegant C19th gold and white cup - can fit next to a bedside, comes ready arranged so it won't need another vase, and when the flowers fade there will be something left, a beautiful cup which will perhaps become a family heirloom. This one sold on Friday but I usually have a range available from £11.50 at the van, from £16.50 delivered within a 12 mile radius. They are also available as table centres for weddings and parties for when a "village fete" kind of feel is required - it is one way of getting a pretty vintage tea set, though I also loan the cups and saucers out.
I always feel sad when I see so many bunches of flowers propped in sinks or even just left on kitchen work surfaces as there are just no more vases to put flowers in.
