>BlankHello - I wonder if anyone could give advice on propagating P.triste.
I've pasted below a couple of items I saved from several years ago (on
Fat-Plants I believe..). I grew two triste's for a year but discarded them
to concentrate on hybrids in my limited space. An interesting plant

Leaves are carrot like, being quite finely divided, and very
hairy. Flowers are produced on branched stems, and
are variable from almost all yellow through yellow with
slight brownish patches on the lower petals. Easily propagated
from seed, but even easier by tuber divisions. This species
should be grown in a large container, as the tuberous root system
is very large, and a plant will never reach the beauty of a
mature plant in a small container.
Plants that are watered all year tend to struggle and
make very weak growth. They should be allowed dormancy
