Ted,

Rob certainly knows his Paph info...spot on
everytime!

Following on delenatii breeding..almost all
delenatii crosses prove to be infertile beyond the
initial crosses.
Yes there are vigorous primary crosses (species x
species) such as you have, but the next
generations prove to be almost universally
impossible. A great pity as many saw it a route
for pink breeding.

There are also some very difficult delantii
crosses to flower such as Delrosi (P.delenatii x
rothschildianum) you probably will have to wait a
good 10 yrs plus to get them to flower.

In passing most people in the volume business are
now beginning to realise that you will never be
able to produce large numbers of Parvisepalum
hybrids. (Unless they get some super fertile
clones - I believe there are some around but not
many). A few hundred but never thousands from a
pod. Most of the Dutch have given up on them as a
pot plant.

In passing if you want to explore some info on
Paph breeding check out my website for a section
on Paph seed.

Terrific. I take it, from what you say, that
delenatii is both a prolific
producer of seed and hardy to the point of being
almost indestructible.
Does it generally pass that on to hybrids it is
used to make?


Well, if I can grow it, perhaps
indestructable. It is pretty
bulletproof for a species. And in terms of seed,
enough for my
purposes, which was never more than a few flasks.
Some crosses don't
take. Some hybrids are not fertile. Most
probably are, although all
the combinations haven't been tried, of course.

more orchids, obtain more credit
