I didn't look closely at the seeds when they were planted. They have been
flowering for a week now. I should have seeds in another month. Scapes
are 12 to 20 cm. with about 10 flowers. Looking very closely, the scapes
look to be glandular-hairy. Petal color is very dark - definite lavender or
purple rather than pink. Stipules are "conspicuous" - I can make out little
hairs pointing straight up from the crown of each rosette if I look closely at
the plant from the side and with good light behind the plant.

D. prolifera (and D. adelae) grows well in indirect light and should do well
in an east or west facing windowsill if they're grown with baggies over them
to raise the humidity to near 100%. Direct sun for an hour a day shouldn't
be a problem. I've never noticed a big difference in temperature inside the
baggie after two hours of direct sun. Poke a hole on top of the baggie with
your finger to allow for air exchange. I water from the bottom with a tray
only when the plant needs it. You can check the wetness of the soil by
looking at the condensation of water on the baggie, or by lifting the plant
and feeling the weight. My plants only need watering every three to four
weeks. Temperatures on the windowsill run from 45 to 70 F in winter and
70 to 80 F in summer. D. schizandra is probably a little more sensitive.
I have a mass of D. adelae growing in a seedling tray 24" x 12" and 2" high
with a plastic cover over it. Never counted the individual plants, but
there's probably well over 100.
