Hi Filippo, Loyd Wix, ChrisTeichreb and other P. villosists

I also believed that P. villosa is a long-day plant and that my earlier
cultivation failures were due to insufficient day length. In the meanwhile
Jan Schlauer has found literature clearly showing P. villosa from North
Corea at 42 degree N which is at the same latitude as e.g. Rome or Boston.
Since 4 years I cultivate P. villosa from Scandinavia and Siberia in a
cooled setting where temperature does not exceed 18 Celsius even in full
sun, at 47 degree N without artificial day length extension. But I agree
that this species needs much sun and is - as also P. variegata and algida -
really very delicate to cultivate.

Right! I I'd really be some years younger without this species ;-). Juerg
