Sometimes pictures say more than words! The first two are flowers that traditionally bloom in the winter. The daffodils were the first of the year last year, pictured on a lovely sunny day. The Veronica was a little sparse when I took the picture, but later became a mass of soft pink blossom that is a joy in winter.

This rose never ceases to amaze us. It flowers in profusion from June until early February, this picture was taken in late December.
And this poor Magnolia is flowering in spite of snow in April. Maybe the next question should be 'when does winter end?'
