    Default Paph. delenatii



    The tale of Paph. delenatii is quite the interesting one from a standpoint of orchid conservation. It was initially discovered by a French army officer in northern Vietnam in 1913, and was named after the director of a French botanical garden. However, all of the collected plants died shortly after importation, save for one plant sent to the firm of Vacherot and Lecoufle in Paris. That plant was selfed and is believed to have given rise to all the Paph. delenatii in cultivation, thereby showcasing the potential of artificial propagation in maintaining a rare species in cultivation. The species was rediscovered in 1922 and was formally described at that time.

    For nearly 70 years, there would be no further reports of Paph. delenatii in the wild, and the species was thought to be extinct. In the early 1990s, however, the species was rediscovered in Vietnam, populations were stripped, and plants quickly made their way to Asia, Europe, and the United States. Fortunately, the "new strain" of delenatii is now widely available in cultivation, and with that one hopes that the desire for wild-collected delenatii has decreased accordingly.

    Paph. delenatii is an easy enough grower under standard paphiopedilum conditions. It is one of the few fragrant paphs, with a pleasant scent that has been described as citrus or rose-like. Of note, Paph. delenatii is perhaps the only member of section Parvisepalum that does not grow in close contact with limestone. Quite the contrary, it is reported to grow in acidic, granite-derived substrates, and for this reason lime supplementation is not recommended. The new strain of delenatii produces flowers that are extremely similar to those from the original strain, save for perhaps slightly larger flowers and diminished or absent fragrance. In addition, new color forms of delenatii have been discovered in recent years, including a pure white alba form and another form reported to have a solid dark red pouch.

    That is wonderful! I would love to see the one with the dark red pouch. I bet it is something! Thanks for the wonderful information again, Jason. I always feel like I learn so much from posts like this one.

    Cheers,

    It's always a pleasure to see a beautiful delenatii. Thank you very much Jason.

    My first delenatii came from lecouffle and was much bigger than the others, and hard to grow (collected ???). It is still in life now but I always suspected that this delenatii was different from those you find now in cultivation.

    I notice too that a delenatii do not like much dolomite (calcium) et prefers a acid Ph (6-6.5)

    I think the last delenatii form you speak about is "dunkel" or "vinicolor". I will be able to show here the flower of this form in few weeks (in spike now).

    Very informative, thanks. I killed my delenatii a few months back, don't know why - could be the neem oil or the spider mites. But I bought another one immediately and has been very careful with mite preventions.

    Thanks for the info and pic Jason. I have a delantii and am hoping to keep it alive long enough for it to flower. I don't have much luck with paphs

    I love delanatii...took me a long time to learn how to grow it correctly...I treat it more like a phrag...bark mix with sphagnum. I keep it wet, but not as wet as a phrag. Now I find it an easy plant to grow and bloom....Take care, Eric

    yes philippe, the dunkel form is the one with the dark pouch. saw a few for sale years back at the NY show but didn't feel like spending 100 on a small seedling. the leaves are supposed to have a red margin on that strain...

    The leaves also vary on the dunkel form. There are a few of them in the greenhouse. Jason, I have seen some fairly recent pics of orchids in a market place and there were piles of collected delanatii.

    Maybe it's easer and less expensive in Europe to find the dark form, especially in Germany

    Just to compare leaves:

    Regular delenatii


    alba form


    Dunkel form. The margin is very dark
