(plant seeds, vegetative parts, cuttings, etc.)
Reproduction
by seeds. Seed - sow
spring in a cold frame. Prick out the seedlings into individual pots when they
are large enough to handle - if you want to produce clumps more quickly then
put three plants in each pot. Grow them on in the greenhouse for at least their
first winter and plant them out into their permanent positions in spring once
they are growing vigorously and are large enough. Division in
spring. Very easy, the plants divide successfully at any time in the
growing season and the divisions can be planted straight out into their
permanent positions if required.

Medium to course soils. pH between 6 and 8.
Care requirements after
installed (water weekly, water once etc.)
Requires little moisture.
Normal rate of growth or
