detailed seed-starting info below

One of the common annuals found in sixpacks in all the big stores during the spring rush, grown for its puffy flower clusters of pure blue. The photographic effect of the blues in some flowers turning to pink is sometimes called the 'Ageratum Effect' - apparently they reflect infrared more strongly, which is incorrectly interpreted as visible red by (some) cameras. Luckily, it appears my current camera isn't fooled. We hadn't grown it in a while, so I started some from seed this year. The seedlings were weak-growing, and only a few survived, but I was surprised at how large the plants grew once the temperature turned warm much larger than the ones I remember from those annual packs.

This plant used to grow in our garden, but it slipped away...
