The genus Cremanthodium is often regarded as being
difficult in cultivation but in my experience of one species, C. ellisii, this
has not proved to be the case. If a few basic requirements are met, most
growers (at least in Scottish or similar climates) should have some success and
enjoy its fine display of "mini sunflowers".
According to Polunin, C
ellisii has a wide distribution from Kashmir to SE Tibet. I have personally
seen it growing in Central Nepal on cliff ledges, at the base of rocks and on
east facing slopes at about 4500m. The plants on the open slopes formed large
colonies while the cliff dwellers were mainly solitary. It is certain that
these plants have a good supply of water during the growing season due to the
monsoon, do not suffer baking hot temperatures at any time and are protected by
snow cover during the worst of the winter weather. All this gives a good
indication of its cultural needs Although it should be noted that we have never
found winter protection necessary here at Tough in Aberdeenshire.
We obtained
seed of C&Mc 383 collected at 4050m above the Rohtang Pass in Himachal
Pradesh. Not all the seed was viable but a reasonable number germinated and
were pricked out into 7cm plastic pots. After a short growing period of about
two months, and in mid-summer, the seedlings disappeared and at first sight
appeared to have damped off This was not, however the case. Next spring they
re-appeared and grew on quickly. We have had a similar experience with C
arnicoides and wonder how many pots of these seedlings are thrown out, believed
dead when in fact they are simply dormant. It could be that this early dormancy
is brought about by overly dry conditions but this has not been proven. We have
seen the same sort of behaviour with Dodecatheon.
We kept the plants in their
pots until August 1993 ( mainly because I forget to plant them out before then)
and then found a space for a group of them in a bed beside our house which is
sheltered from the south by a north-facing gable end and from the west by high
shrubs. The soil here is acid, fairly heavy and moisture retentive but the bed
is raised and well drained. It only gets sun in the early evening and is a very
cold spot in the garden all year round. The plants flowered for the first time
in June 1994 with only one or two blooms but in July 1995 they flowered again,
producing a wealth of nodding blooms on stems of about 25 cm and setting a
great deal of seed.
The main requirements of this species would appear to be a
very cool moist spot that never dries out nor becomes saturated in winter, some
protection from slugs which relish the new foliage and a good deal of patience
on the part of the grower who will, in the end, be rewarded by this unusual and
very attractive plant.
