This post is on plant combination number 3. I realized that all three plant combinations include a blue flowering plant: Virginia Bluebells, Blue-Eyed Grass and now Willowleaf Bluestar.
Blue, in all its shades and hues from royal purple to light blue or violet, is actually a great supporting plant. True blue is a primary colour. It works best with the softer hues of pink, pale yellow, white and creams. Think spring time. You will find its neighbour purple or violet on the colour wheel opposite the reds. Planting these complementary colours creates stronger contrasts which typically are found in summer and fall gardens.
Above left is Willowleaf Bluestar or Amsonia Tabernaemontana . A great plant for its willow-like leaves and pale blue star shaped flowers in spring. This is one of those sway- in- the- breeze plants, and mine grows over 3 feet tall and wide. I have heard of its wonderful yellow leaf colour in the fall but this has not been my experience. It gets little TLC apart from some compost at its base every year or two, and bugs and diseases seem to leave it alone. To its right is a perennial Geranium sanguineum 'Max Frei' and a dwarf Willowleaf Bluestar.
My dwarf Amsonia is not a cultivar like , for example 'Blue Ice', but rather Amsonia tabernaemontana var. montana. I think that puts it in the natural hybrid category, but really who cares! This baby tops out at 1 foot in my garden and stands more at attention than its larger cousin. Plus its flowers are a darker blue when in bud. Teamed with these bluestars is the Geranium Max Frei, a vibrant hue of pink especially on cloudy days, that makes the entire combination pop.
