It is yellow, it climbs and flowers in Autumn. It’s a hardy herbaceous perennial and thrives on a wall of any aspect. I have seen it equally magnificent on walls north and south.
It is described as scandent and clambers everywhere. This can be it’s Achilles heel as it will scramble all over other plants. It is perhaps best planted with a space to itself with netting to cling to. An alternative strategy is to let it grow over a coarse hedge or shrub.
Although D.macrocapnos is completely hardy, it overwinters best at the base of a wall.
Although it is herbaceous and dies to the ground, I have never succeeded in propagating it by division. It is quick and easy from seed, as is the almost identical Dicentra scandens.
Both are available from Chilterns Seeds.
