Lilium formosanum

John:
Funny that you should mention Lilium formosanum as I am currently
botanizing in Taiwan and one of my goals was to observe this species in
situ. At elevations of 3000', it reaches 5-6' tall and indeed as you
climb, the stature drops to plants that flower at only 1' tall when you
reach the alpine regions above 9500' elevation. It will be very
interesting to see if these "dwarf" forms have changed genetically when
they are grown at lower elevations. As you also indicate, it typically
has only one flower per plant, but where they have been transplanted into
cultivation, some stalks have as many as 8-12 flowers. So far, all plants
have purple striping on the flower backs. These alpine forms should love
the weather in the UK.
My sole contribution to the Flora of Tropical East Africa has been to
write
the account of the Liliaceae - this sounds quite grand, but in fact the
only
representative is the alien Lilium formosanum! Nevertheless this warrants
a
'fascicle' (individual portion of the work) of its own, and is available
from RBG Kew for the sum of £12.90 (one folded sheet of A4 paper inside
covers!). Please note that the author does not receive royalties.
Anyway, in researching this species I came to the conclusion that var.
pricei is probably not tenable, as there seems to be a continuum of
stature
in the wild, and that the minuscule things in cultivation under that name
are probably the result of selections from selections brought back by
William Price from 'Formosa' (Taiwan) in 1912. These would probably be
best
treated as L. formosanum Pricei Group in horticulture. Incidentally,
William
Price lived about a mile up the valley here and is remembered by some
older
residents: he accompanied H.J. Elwes of Colesbourne on his journey to
Taiwan. He also collected a clone of Pleione formosana long-known as P.
pricei, but now called P. formosana 'Oriental Grace'.
The other thing that is very striking is that in wild/naturalised
situations
it is almost always single-flowered, whereas in cultivation it can be
multi-flowered. I have not seen the JC Raulston stock (mentioned by Jim
Waddick in starting this thread) in flower, but have seen its towering
capsules in winter and thought it was magnificent even then. L. formosanum
is in general not a great success in the UK, perhaps because of virus, but
also I think it needs a hotter summer than we can provide (even in a good
year).
