I got 3 of these a few months ago and the plants looked quite tiny, they are bursting with blooms now and so pretty. They appear to really thrive in full sun, I have one in a shadier spot and it is growing more slowly and has not flowered yet. The flowers are a lovely pale periwinkle blue with a vibrant orange eye. The contrast is very striking. I'm also growing the black knight, white profusion, and bicolor. Now that I've seen these bloom, I am pretty pleased! Highly recommend!

Fragrant trusses of rich violet-blue flowers with an orange eye are wonderful in the late summer border or the late summer bouquet. Sun/Med
