height on seed packet says 30" and mine have grown that tall, but want to lean to ground rather than stand upright. branches will grow upright off any branch that goes over sideways. I do not find folliage attractive, tends to curl inward, maybe something wrong with them. I would call color "periwinkle" lavender/blue, the plants saving grace. The flowers look almost fluorescent in the late afternoon/early evening light. OK if something is planted in front of them to hide folliage. I will probably not buy again.

Zone 9b - This has been a no care plant for me. Blooms year round with minimal care. I love it! It spreads and stays low. Looks really good with pinks. SILady

Something about the tall ageratums that I prefer over the short bedding types. 'Blue Horizon' is a great cultivar. It blooms all summer, makes great cut flowers, and the butterflies LOVE it. It grows 16-18 inches tall and is a wonderful garden plant. It's seeds are sterile so don't bother collecting them... buy from a reliable source.
