Cultivation details
Succeeds in most fertile well-drained soils[233], though it prefers a sunny position in a moist but well-drained rich sandy loam and a neutral or alkaline soil[1, 200]. Strongly resents winter wet[1].
This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. Plants may require protection in severe winters[1], though they have proved reliable in Cornwall[K].
This species provides some of the nicest salad leaves that we have tried to date, it has an excellent potential as an edible ornamental in the garden, though it is not really suitable for commercial cultivation[K]. The plants have a basal rosette in winter and continue to grow slowly in all but the coldest weather, providing edible leaves most winters[K].
The species in this genus do not often hybridize and so seed can generally be relied upon to come true[221]. The plants are self-fertile[221].
A very ornamental plant[1]. It is closely related to C. pyramidalis, but is more reliably perennial[221].
Members of this genus are rarely if ever troubled by browsing deer[233].
Propagation
Seed - surface sow spring in a cold frame. The seed usually germinates in 2 - 4 weeks at 18°c[138]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer.
Basal cuttings in spring[200]. Once they are a few years old, plants produce a number of rosettes and these can be carefully removed in the spring and used as cuttings[221]. Harvest the shoots when they are about 10 - 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
Root cuttings are said to work[221]. The plant has a thick fleshy root with a number of crowns. Whilst this can be divided if great care is taken not to damage the root, it is not really recommended because the divisions take a long time to become established[221].

[1] F. Chittendon.RHS Dictionary of Plants plus Supplement. 1956 Oxford University Press 1951 Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[46] Uphof. J. C. Th.Dictionary of Economic Plants. Weinheim 1959 An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[50] ?Flora Europaea Cambridge University Press 1964 An immense work in 6 volumes (including the index). The standard reference flora for europe, it is very terse though and with very little extra information. Not for the casual reader.
[61] Usher. G.A Dictionary of Plants Used by Man. Constable 1974 ISBN 0094579202 Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[105] Tanaka. T.Tanaka's Cyclopaedia of Edible Plants of the World. Keigaku Publishing 1976 The most comprehensive guide to edible plants I've come across. Only the briefest entry for each species, though, and some of the entries are more than a little dubious. Not for the casual reader.
