VARIETIES: There is a single species – A. Sylvester, formerly known asaruncus. It may take a year or two to become properly established, but given the right conditions Aruncus will reach 6 ft or more. Set the plants 2.5 ft apart. A. Sylvester is too large for most gardens – choose the variety ‘Kneiffii’ (2 ft) where space is limited.
SITE AND SOIL: Any reasonable garden soil will do – add organic matter before planting. Choose a spot which receives some shade during the day.
PROPAGATION: Divide clumps in autumn – mature plants are difficult to split.
