How it is grown

Succeeds in most soils, including dry ones, preferring a rich moist soil and a sunny position but tolerating partial shade. Plants flower less freely in a shady position though the flowers can last longer in such a position. Grows well in heavy clay soils. Succeeds in short grass if the soil is moist. Prefers a pH between 6 and 7. Hybridizes freely with other members of this genus. Plants take a year or two to become established after being moved. They increase by means of runners and form loose spreading clumps. The roots are not swollen. Plants seem to be immune to the predations of rabbits. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk. The fragrant flowers are very short-lived, they open in the late afternoon and die in the morning. However, plants produce a succession of flowers for several weeks of the summer, each scape carrying between 4 and 20 blooms.

Propagating it: Seed - sow in the middle of spring in a greenhouse. Germination is usually fairly rapid and good. Prick out the seedlings into individual pots when they are large enough to handle. Grow the plants on for their first winter in a greenhouse and plant out in late spring. Division in spring or after flowering in late summer or autumn. Division is very quick and easy, succeeding at almost any time of the year. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Things to keep in mind

Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component. (This report does not make clear what it means by blanching, it could be excluding light from the growing shoots or immersing in boiling water.)
