Hemp Agrimony (Cnáib uisce)

Eupatorium cannabinum must be one of the most popular among bees and butterflies. Native throughout Ireland and found by ponds, rivers, on seacliffs and indeed in ditches, this is a big plant, with nice upright and reddish, branched stems carrying racemes of wide flat flowerheads with tiny pink flowers from July to September. Will add height to any border and, for sure, visitors to the wildlife-friendly garden.
