I recall that CPN covered some of these uncommon hybrids a few
years ago. The capensis crossed with some of the rosetted forms
produced a quite nice hybrid. There were however chromosomal limits
as to which drosera could be crossed with which, if I recall the
article correctly.

Janice, in case it's not clear, most (all?) sundew flowers only open
for an hour or three each day, one per day. As they are used
they close up, leaving some of the petals sticking out of the
end of the capsule, which gradually dries. On a multi-bloom
scape, such as capensis, the scape starts to straighten out
further as the flowers bloom. Most drosera seed looks like
finely ground pepper, and can be easily mistaken for dust or
flower fragments if you're used to larger seed.
