Eupatorium cannabinum (Hemp agrimony) 9 cm Pot

Growth habit & appearance: Eupatorium cannabinum forms an upright clump of striking, reddish-tinged stems topped with domed sprays of pale rose to dusky pink flowers. The foliage is divided and slightly coarse in texture, giving the plant a wild, riverside character. In midsummer the tall stems and soft, tufted blooms create a strong visual presence and draw in butterflies, bees and hoverflies in large numbers.

Growing conditions: Native to Europe and fully hardy, Hemp agrimony thrives in damp ground, stream edges, wet meadows and lightly shaded woodland margins. It tolerates both full sun and partial shade, but performs best where the soil holds moisture without becoming stagnant. In drier gardens, incorporating leaf mould or compost helps maintain the steady moisture levels it prefers.

Traditional & herbal uses: Traditionally noted for supporting immune response, and historically associated with feverish conditions, flu-type symptoms and gentle laxative effects.

Maintenance & harvesting: Cut back old stems in late winter or early spring to encourage fresh growth. In naturally damp areas maintenance is minimal, but in dry spells provide occasional watering to prevent stress. Harvest aerial parts during peak flowering on a dry day, and roots later in the season once foliage begins to decline. Plants can spread slowly via rhizomes, so divide established clumps every few years if tighter control or rejuvenation is needed.
