Anyone grown this new ageratum Artist Alto Blue?

19 years ago

I just bought six plants of Ageratum Artist Alto Blue. They are a Proven Winners plant. I have been looking for a tall ageratum to replace Blue Horizon, which I can't find anymore. Has anyone grown this new ageratum in the "Artist" series, color is "Alto Blue"? My big question is how tall does it get? The tag says 12:-18" but I'd like to hear from anyone who has grown it. Any other tips? The small plants look great but I hope they get tall.
