This species is said to be difficult (but not impossible) to divide (in early spring only!) and I've never attempted it. It can also be grown from seed.
The RHS awarded this plant its coveted Award of Garden Merit. According to their information, it likes its soil moist but well drained, tolerates a wide pH range, and grows on "loam, chalk, or sand".
