Autumn Monkshood

Aconitum carmichaelii 'Arendsii'

Striking blue blossoms open on long flower spikes supported by glossy dark green foliage.

Monkshood are wonderful old-fashioned perennials, perfectly suited for large border plantings. This late-flowering selection has incredible, tall spikes of deep violet-blue, hooded flowers, a total surprise when they appear in mid-autumn. Attractive dark green, glossy foliage. Stems may need to be staked in summer. An outstanding cut flower. Plants prefer a site that will not dry out in summer, away from thirsty tree roots. Easily divided every 3 to 4 years, in early spring. CAUTION: toxic if eaten/harmful via skin.
