Graceful and elegant. I am in zone 5a so I grow it in a rolling planter and move it into my unheated garage in the winter. It blooms for months and is compact and upright. It does require acidifying which I implement with an acid based fertilizer. It can become chlorotic but with Muracid or Ironite bounces back quickly. In acid soil it is blue lavender. I only moderately acidify so mine are pinky mauve.
