Yellow seems to be the dominant color of early spring. Daffodils, carolina jessamine, witch hazel, Lady Banks rose, forsythia - it seems the list is endless. Here are two yellows that I photographed yesterday. My Lady Banks rose has just started and I will be posting a photo of it later.
Kerria Japonica (also known as Easter Rose) blooms before the leaves appear. It is a graceful and dependable shrub.
Carolina Jessamine is a fast-growing vine that can be used in a variety of ways. I have mine growing on a low picket fence next to my tiny vegetable garden.
