Blue Ageratum is an annual with one of the truest blue flowers to be found. And they are very easy to grow from seed.

It is in the daisy family so needs deadheading, otherwise, it is care free.

Ageratum looks lovely in containers as a filler, paired with dusty miller, blue salvia and white alyssum.
