Generic delimitation in Astereae has long been a source of disagreement among botanists. The ways in which they treat the large and diverse genus Aster usually reflect their philosophy on generic concepts, and although there are many variations, in general there have historically been two schools of thought. The first approach maintains a very inclusive generic concept of a large genus Aster, with subdivision of the genus into several subgenera. The second approach was to segregate many distinctive small genera from Aster, thus adopting a narrow generic concept As a result of new in-depth studies of phenotype features and, more recently, DNA sequences, combined with reasonably strict adherence to the tenets of phylogenetic systematics, the genus Aster is now much more narrowly and more naturally defined than before. Consequently many of the species, including this one, that were formerly accepted in a looser definition of that genus have now been transferred to several more narrowly defined genera.

Kalimeris pinnatifida is a herbaceous, perennial plant with a creeping rhizome. It produces a cluster of erect stems 40 - 150cm tall[
The plant is cultivated as a vegetable in Japan and is also commonly grown as an ornamental[
E. Asia - central Japan.
Hills and low mountains[
|Cultivation Status||Ornamental, Wild
Prefers a moist loamy soil[
] though it succeeds in most soils[
]. It is easily grown in average, medium, well-drained soils in full sun to part shade., preferring full sun in the northern part of its range, but appreciating some afternoon shade in hotter climates[

Seed - sow spring in a greenhouse and only just cover. Keep the compost moist. The seed usually germinates in 2 - 3 weeks at 15°c[
]. Grow on in cool conditions, about 10°c[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division in spring. This should be done at least every 3 years in order to maintain the vigour of the plant.
