Nothing announces the coming of spring better than the blooming of forsythia. Even in dead winter this tough shurb is ready to go as soon as a warm spell comes along. The bright yellow flowers that cover the gracefully arching stems bring a burst of warmth to even the grayest landscape. And you can bring the stems indoors and force them into bloom if the warm spell doesn’t come when you want it. But please give it plenty of room to reach its full potential beauty; and don’t prune it as though it was a boxwood topiary! Let it grow naturally so its lovely form can be enjoyed.
