So in a moment of frustration with my vandas, I ordered a vandaenopsis (half phal half vanda), thinking it might be more friendly to my conditions. Well, now my vandas are happy, and my vandaenopsis just arrived in the mail. I'm not quite sure what to do with it.
I can't find much online about it, except "Well suited for windowsill culture" (which really doesn't explain anything in my opinion, because each of my windows gets different amounts of light, so no two windowsills are the same), and "These grow well in bright phalaenopsis conditions." So, do I treat it like a phal? That doesn't seem right.
It arrived in a plastic pot with some nasty looking bark and shriveling roots. I cleaned it up, gave it a good soak and potted it in a vented clay pot with coarse bark...then I put it outside with my catts. I'm baffled on this one. My phals are in bark, indoors, away from bright windows. My vandas are in vases outside in the heat. How the heck do I find a mid-point between those two extremes?
Has anyone ever grown one of these things? The grex name is Vandaenopsis "Newberry Whimsy." Any help would be appreciated! Thanks!
Grow it like a Phalaenopsis.
I would grow it like a Phal, but brighter.
It is a quite recent hybrid, registered only in 2011, so no information exists about its offspring. But my educated guess would be that is fertile. Fertility or sterility are not the functions of how far the genera are in the artificial human classification, but more of genetics and genomics. Usually plants with same no. of chromosomes will produce fertile offspring. It has got to do with the equal distribution of chromosomes during gamete formation. Vandas and Phals. both are naturally diploid and have 38 chromosomes (n=19). So the resulting offspring also has 38 chromosomes 19 from each parent. Whe this plant wants to form its haploid gametes it can form 2 equal gametes. Now consider a hybrid of a Phalaenopsis and Angraecum. Angraecum sesquipedale has a diploid no. of 42 chromosomes, so its gametes will have 21 chromosomes. The resulting hybrid will have 21+19 = 40 chromosomes. Now when it will form its own gametes it will have to divide its 40 chromosomes equally among the two gametes. Mathematically it is simple 20 chromosomes each, but biologically it is not the same. All the genetic information from the Angraecum parent is distributed on 21 chromosomes whereas genetic information the from the Phalaenopsis parent is distributed on 19 chromosomes. So a gamete that has 20 chromosomes has either more genetic information than necessary (19+1) or less than necessary (21-1) in either case the gamete is non functional. I will write more about this with diagrams and make an article about it over the weekend.
I've been seeing so many of these around lately on this board, it's starting to frustrate me! I've yet to find anyone that sells them and I LOVE them.
People of my generation have had some bad experience with Vandaenopsis. In the late 1950s and 1960s quite a number of breeders tried crossing Phals with vandas. I personally knew 2 who crossed Phal amabilis and V Rothcildiana with the intention of prducing 'blue' phals. Both were failures or hoaxes/cons/scams. Many including myself fell victim and paid quite exorbitant prices for the seedlings. Others came out with Vanda x Phal Doris 4n (the 'hot momma' of the day). After 3-4 years all came out looking like pure white phals. That put paid to Phal x Vanda matings for a time at least.At the time Paraphalaenopsis was classified as a Phalaenopsis and this 'happy hooker' was able and willing to mate with all and sundry within the vandaceous group, and so we had Vandaenopsis registered as a Genus then, which would now be a Paravanda. 3 well-known Vandaenopsis of the period come to mind (they were registered as Vandaenopsis then)Vdnps Prosperitas (Phal/Para denevei x V dearii ); Vdnps Kapden (Phal denevei x V Kapoho); Vdnps Khoo Kay Ann (Phal denevei x V Prolific). Oh yes we had Arachnopsis Eric Holttum ( Phal denevei x Arachnis Maggie Oei).
My point is, a true Vandaenopsis would be a very rare find indeed and I exclude all those that are crossed with Paraphalaenopsis or Doritis (now also classified as Phal by some taxonomist).
Haha I really like the term 'happy hooker' for the Paraphals. Yew, all the shady stuff "failures or hoaxes/cons/scams" that you mentioned have really given a bad name and reputation for the Vandaenopsis, and actually that is whay they might be rare, but I really see no reason why not many people are again starting with good Vandaenopsis crosses. On the other hand there are a plethora of Renanthopsis made with true Phals and not Paraphals. They seem to be quite beautiful, variable and fertile. Renantheras are also breeding freely with vandas, so I think we have another happy hooker in them and the terete leaf vandas which are very promiscuous
And here I thought all free flowering orchids were nymphomaniac's.............................. AL
