Average soil works well for this startlingly beautiful dark purple spikey flowered speedwell. If you prefer putting it into a container, go ahead; make a dramatic statement by setting it above all other plants if you wish. There's nothing like variance in height to add more dimension to your flower garden! It's good in the full or partial sun and flowers towards the beginning of summer.
