How Are Month Flowers Selected?

There is a flower for every month. Each calendar month has got it's got its own unique flower, i.e. Rose is a flower for the month June while Daffodil is March's flower. Months flower actually reflects the months it's being associated with. Since every season has got unique characteristics/features that's why every season should get its own flower also to represent it. Also different colour shades give soothing effects in different environments. For example; black colour looks very odd in summers.

In most regions of the world summers fall in May, June and winters fall in December, January with notable exceptions of Australia and New Zealand that's why month colours are more appropriate for rest of the world rather than Australian's sub-continent. In the Australian sub-continent summers fall in the months of December, January while winters fall in May, June. Also taken into consideration is the availability of a flower in a particular month.

December's flower is Paper-white. It's a white-coloured flower and depicts snow and winter of December. January also falls in snow season that's why its flower is Carnation. It's again a white-coloured flower.

The "flowers of the month" concept can be dated from the Romans.  Flowers were given in each month because that's the month that they were available to give (they bloomed).  Modern conventions had deviated, depending partly what new flowers were available in other parts of the world, or when flowers are cultivated in greenhouses.

January: Snowdrop (traditional, blooms in this month).  Modern=Carnations.  

February: Violets (modern association with St. Valentine's Day), primroses more traditionally.  Primroses actually start blooming in February, in warmer parts of Europe.

March: Jonquil or Daffodils.  Also tend to bloom in this month.

April: Daisy or sweet pea, start blooming this time of year.

May: Hawthorn or Lily of the Valley.  Doesn't look like a lily at all, but is a bell-shaped flower.  Roman legend said that the Nightingale (famous singing bird) won't return until the Lily of the Valley bloomed.

June: The Rose or honeysuckle -- again, the season when it blooms naturally in Europe.

July: Larkspur.  Blooms starting in July.  Greek legend says that the first larkspur grew from the blood of the fallen warrior Ajax.

August: Poppy or Gladiolus.  Gladiolus signifies strength of character.  Poppies are late summer flowers.

September: Aster or Morning Glory.

October: Calendula.  Maybe the only flower left to be seen in early Roman winters.

November: Chrysanthemum.  This wasn't even introduced to Europe until the 1700s.  Since November in early Roman times fell in mid-winter, I have a feeling there simply wasn't a flower for this month originally.

December: Narcissus (Daffodils) was traditional.  Because originally the month called "December" fell in early spring.  Holly became the choice in the middle ages in Europe (red berries appear on holly in December).  Poinsettia is the modern choice.
