Yes, I have several. What do you want to know ?

Or, how about this. Treat it a bit like Neofinetia − i.e. grow in sphagnum
moss, doesn't mind being a bit above the pot with the roots outside the
clump of moss before entering the pot/basket or whatever. Needs good light
to flower. Although it used to be considered to be an Aerides, ( Sedirea is
an anagram of that ) which implies, warmth, Malaya or Indonesia conditions
etc, in fact it will happily grow a bit cooler. I don't know how cool − some
Japanese things will stand frost they say ; if you want to experiment,
that's fine by me, but not with my plants.. I grow all my orchids with
Cattleya conditions.

Burnham have their "mother plant" which has half a dozen or more growths -
although it's a monopodial, it will do this as will Neofinetia − and I have
seen it with half a dozen long spikes on it too − but that's exceptional.
The best I have done so far is about 14 flowers n a single spike, but now
that I follow the above regime, my plant is getting bigger every year, so
here's hoping.

If you want a pic of the plant − not in flower at the moment, let me know
and I'll put one up/

Thanks Geoff for the info. I bought it from the chap on eBay which sells
the Neofinetia's. So I will grow it with them and see how it goes. I do not
think it is flowering size but it is growing well.

I would like to see a picture of your plant, please.

Thanks

you the present size, but they do flower much smaller than this.

Growing orchids for 26 year's+ I only had one Paph. which was given to me by the late botanical artist, Barbara Everard. She grew mainly Paphs. in what I remember was a relatively small lean-to greenhouse.
I will not go into the long tale of the illegal importation of Paph. sanderianum. Edinburgh Botanical gardens had a couple of the plants and flowered one. It was painted and you could buy prints from Dick Warren, who at the same time grew some from seed. I think the initial seedlings were £20+ and I tried a couple later on when the price went down, with no luck. To cut it short , has any member ever flowered this plant and would have a picture of it. The chap who owned Exmoor Orchids , Peter Tremain, flowered it, but never saw it.

I have never seen it in flower, and even to see its hybrids is a rare thing
, even as a member of the Paph Society for many years.

I have had seedlings from Dick Warren (Equatorial Plants) but been
unsuccessful, but that is not unusual , his flasks contain plants of say 1-
2 cm leaf-span at the largest (usually) and everyone finds them difficult.
This indeed is true of 95% of all seedlings sold , they are too small.

On the other hand, when I have bought paph species in flask ( before that
became too difficult for other reasons I won't go into now) from USA, the
average size of the seedlings was 5cm +. In terms of viability, that is a
whole different ball-game. I also buy Paph seedlings in flask from
Ratcliffes , I guess most nowadays are surplus flasks from EYOF, and they
are a similar size.

What a difference with the bigger size , one of the paphs I deflasked 26
months ago has the first flower almost fully open , I'll post when it is
quite out , and I have twenty or more plants now big enough to flower all
from paph flasks bought at the same time , the last time they had any on
offer I assume. I also have perhaps twenty different batches of deflasked
seedlings of other things, bought from various sources over the last two
years all still in my dew-point cabinet, and not big enough to come out into
the wide world, and years and years away from flowering.

The difference with the bigger seedlings I think is that they have been
re-plated once or twice, instead of just sold almost as soon as the leaves
can be seen Of course, most of Equatorial Plants sales (?) are to
professional nurseries, who can buy their flasks, re-plate themselves, grow
into big husky seedlings in flask, and then take them out and produce
flowering plants in a small number of years, We can't, unless we are going
to set up a lab of some kind.

Back to sanderianum , the other thing is that Dick sold those seedlings for
years and years , maybe still does ; I asked him once if he managed to get
Edinburgh to set a seed pod periodically , and the answer was no , it had
only been done once , but every time he de-flasks, there are a few
protocorms which are still proliferating , maybe he then divides them) which
sets him off again with a new mother flask

A sort of Peter Pan operation. Maybe they don't want to grow up and flower
even when they do leave the flask for the wide world ?

I wonder, by if Edinburgh still have the parent plant ? They have a National
Collection fo Dendrobes, too , but when I have been there , perhaps three or
four times in my life, I have never seen hide nor hair of any orchids
whatsoever. Perhaps they have them all in their herbarium , pressed and
dried and mounted.. or am I just a cynic ?

I knew Dick Warren quite well but have not spoken to him for years. I took his newsletter for 15+ years and bought a load of seedlings over the years.
95% did not grow to flowering size. As Geoff. said they were just too small.
Being an analytical chemist(retired) I made a glove box and grew my own orchids from seed. I could replate them and grow them on to a good size and had a better chance to reach flowering size. It took 3 years to flower Aspasia lunata. I used to buy seed from a BraIlian nursery ,Alvim Seidel.
I actually grew orchids from seed at the start using a large poly. bag wiped out with bleach. It worked quite well.

Hello peter − I often wonder how the early hybridists produced any plants
and have been reading my old 'Orchid Reviews'. They mention that Sir
Jeremiah Colman published privately a book on growing from seed and being
an amateur 'divulged secrets that those in the trade would not'. i have
tried several methods such as mossy bricks and round the parents roots
but, except for Disa, without success. I wonder if anyone has read that
book?

My wife bought me a few paph flasks for my Xmas present 2 years ago (
December 2008). I think I have shown some pics of the seedlings , from time
to time. Here is the first to flower − P.Lemon Hart x (Betty Bracey x Jolly
Green Gem).

One chuffed Paph Grower !...

Geoff

p.s. Tricia − I'll number and title this and include in my next batch in the
usual way ,so you won't need this for the archive from this particular
mailing, but I was just sending this to the originator/supplier for comment
- and , truth to tell , to show off a bit. Its always nice to flower
something quicker than the originator − although I don't actually know if
this is the case here.

Browsing my garden centre ( looking to stock up on RoseClear _) I was − as
so often − surprised and disappointed at the very poor range of insecticides
now on offer, due of course top the latest batch of EU Rules, or at least -
I suppose − the interpretation of them by DEFRA or somebody. But I did find
a product called (Westland) Plant Rescue, said to be effective against most
of the pests we suffer from , i.e. Mealy Bug, Scale and Red Spider Mite. (
also whitefly, thrips and aphids − which may worry you if you also grow
other ornamentals in the same greenhouse ). I bought one for spot use if
and when needful.

Geoff,

According to the labels that I can find, Westland Plant Rescue is a
mixture of thiamethoxam and abamectin, but the Westland advertisements
found so far do not state the concentration of either chemical.
Thiomethoxam is a neonicotinoid, thus related to imidichloprid, etc.
Abamectin is what is commonly sold as Avermectin and Avid.
Thiamethoxam sold here for greenhouse use is under the name
Flagship. At least one regional chemical supplier has a 25%
concentration of Flagship in 8 oz plastic bottles for US$205 each! I
am unaware of any home garden packaging for thiamethoxam over here,
at least nothing that is approved by numerous States and thus
widespread.

What is the labelled concentration on your bottles?

I would be interested to hear of your success with this mixture. It
should work well for many of the common plant and nuisance pests in
orchid houses, but I find no recommendations for hard scale, such as
Boisduval's.

Geoff, I know they are meant to be grown in darkish places but aerangis fastuosa and aerangis luteo-alba var rhodosticta are grown in normal light but completely shaded from the sunny brighter parts of the greenhouse. ie they are under 50% aluminium strip shading and plants growing outside throw a shadow over that part.

Yes, it is so difficult talking about light you don t happen to have a lux meter, and be able to give actual readings, I expect.

Geoff, when I spoke to David about this some time ago, he used the
term 'Stygian gloom' − just checking, it was regarding Aerangis
wasn't it, David?

It gives a good idea, even without a lux meter :-)

To steal ideas from one person is plagiarism; to steal from many is research.

Re; Light, illumination, measuring and lux meters

Browsing through iPhone apps I came across a a lux meter. Not free; it costs all of 0.59p !

It calls itself Pro but, then so does my toothbrush.

Anyway, if you happen to use an iPhone and your technical budget runs to 59p, you could do worse than give it a try. So long as it gives consistent results I guess it doesn t matter too much if the readings are only ball-park figures. In any case, I once borrowed a university physics department instrument for playing with artificial light but that proved to have a mind of its own unless I set up an accurate jig for repeated measurements of the same source.

An old Weston Master light meter can also be re-calibrated but I forget the conversion figures.

Hello Geoff,
This might be difficult or even impossible.
I bought a Bewi Automat in Germany when I was in the RAF in 1958 because I couldn t afford a Weston Master on 25 bob a week. I used it with my rollieflex and it gave good results.Anyway I have just dug it out and it still works!! At 100 ASA it gives a reading of 1 second at f 22 but no lux readings.
Maybe you can convert that back somehow.
