This was another penstemon that did not make it in newfoundland, presumably due to too much winter wet. It forms a low, spreading mat of small, blue-grey leaves and small violet flowers with blue lobes. It would probably do better in a wet climate if grown in an alpine trough or a scree. It is an attractive plant in or out of flower.
