Ageratum choices recommended by Nancy Szerlag in her Annuals For Michigan by Lone Pine Press.
A. houstonianum forms a large, leggy mound that can grow up to 24" tall. Clusters of fuzzy blue, white or pink flowers are held above the foliage. There are many cultivars available; most have been developed to maintain a low compact form that is more useful in the border.
‘Bavaria’ grows about 10" tall with blue and white bicolored flowers.
‘Blue Hawaii’ is a compact plant, 6–8" tall, with blue flowers.
‘Pinky Improved’ is a compact plant with subtle, dusky pink flowers.
‘Summer Snow’ has white flowers. The tall variety
‘Blue Horizon’ produces blue lavender blue flowers on 2 to 3 foot stems.
