Cornus sanguinea ‘Midwinter Fire’

Halving the number of days between December 21 and March 21 lands us on Tuesday February 5, 2008 sometime around noon. As this midwinter hump approaches I am curious about the use of seasons. While I know that “winter” and “summer” are created by the tilt in the Earth’s axis which places us in northern hemisphere closer or further from the Sun at different times of year resulting in variable temperatures; what I don’t know is where winter starts. I mean at what latitude do people call the season winter (for the english speaking world). Do other languages account for more than four seasons? There is of course the rainy season and the dry season in many places. Can seasons be named after colors? Certainly we could look at the color studies of Johannes Itten (page 23) and pick out the seasons quite easily…

In any event, the Red Twig Dogwood is a wonderful plant with particular winter interest that thrives in full sun and should be cut back at the end of each winter. It lives with the other Cornus species in the Dogwood collection at the National Arboretum and is tough to miss this time of year. Happy midwinter…
