Division in spring or autumn is also straightforward — larger clumps can be replanted directly into permanent positions, while smaller clumps are best potted up and grown on in a cold frame until rooting well, then planted out in summer or the following spring.

Other Uses

The seed of all thistle species yields a good oil by expression, though no details of potential yields are given.

Notes

There are about 150-250 Cirsium species. They grow in temperate regions.
