I bought my first Arkansas bluestar at a Master Gardener’s Fall plant sale. It was a puny little plant but since I had never had one but had always heard they were great garden plants, I bought it for 25 cents. I didn’t get around to planting it until the following year but it survived. It did nothing the first year but since I always give a new plant at least 2 years before pitching it this one was given another chance. That second year in the garden the large clump that emerged from the soil produced clusters of light blue flowers above delicate, fine foliage. The flowers only last a couple of weeks but the foliage provided a nice contrast with the other plants in the border and provides a lovely backdrop for lower growing annuals and perennials all summer long. In fall the foliage turns bright yellow and adds a really spectacular bright spot in the garden. A native of south central US, it does well in borders, cottage gardens, rock gardens, and open woodland gardens.
