Lovely plant, switches from pale blue to deep purple and keeps the purple for months! So many blooms. Highly recommended.

I had great germination on entire packet. Beautiful purple blooms. Had color from these for months! Will be planting more next year but in clusters for a more full and striking visual.

I'm sorry to report that these did not grow. The excessive rain interfered with many, many of my seeds. But I am certain the seed quality was not the issue.
