ACONITUM CARMICHAELII VAR. ARENDSII
This is the rarely-offered, very latest form of any of the "Monkshood" plants to flower here at Plant World. It's a cross between A. carmichaelii and A. carmichaelii var wilsonii and the long stems produce buds in August and September with the deepest inky blue flowers opening still later. These magnificent spikes of extraordinarily large flowers are only damaged by the first frosts in late October and November.
For best results, sow seeds as soon as you receive them in a cool place onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. These seeds can be very slow indeed to germinate, and as a rule they wait for spring before emerging whenever they are sown. Please be very patient, and do not discard the seed pan, no matter how long it takes for germination to occur.
