The pale yellow-green of the witch hazel flower. The dark waxy green of the magnolia leaf. The slight green cast of the March lawn as it stirs to life — these are the greens I see here today.

But in my mind are other greens: the Cliffs of Moher, their ancient, mossy backs emerging from the fog on the west coast of Ireland. The furze that carpets the barren ground. The fields emerald in the sunlight. The many greens of the old sod. It is a day when sentimentality is allowed, singing is encouraged — and green is celebrated.
