Coming Along.

Great looking specimen tree. Planted last April in container. Bloomed by mid-May. And although the flowers aren’t as colored up as advertised just yet, it’s still one of my favorites.

True Blue Butterfly Bush (Tree Form)

Blooming nicely. Received in April, planted after 7 days in the garage to avoid a late frost. Produced flowers soon after and still going strong.

Off color

Beautiful leaf color, a nice grey - green. The flowers aren’t the same as the picture , they are more of a lavender. Maybe it’s just transplant shock and they will adjust, they are still pretty.
