    I think 3 blooms for young plant is reasonable. On average the spike only carry 3-5, unless you got those line breeded clones from KrullSmith. They are just specticular =)

    Thanks for all the comments, y'all. I'm really excited about this paph - it's like discovering a whole new world of slipper orchids. I couldn't tell from photos in my books how beautiful and different Paph. lowii is. I'm glad 3 blooms is okay - I have hopes for more the next blooming. In answer to you question about size, Jason - this is a VERY small plant, especially since the blooms and stem were so large (tall). It has one old growth, the growth that is blooming, and one new growth. As far as I can tell, this isn't a division, so it really IS a young plant. I hope it has survived 12 days without me!




    This is the only photo I have that shows anything like the proportions - but that is a bud vase, and the opening is just a little more than 1/2 inch in diameter. The stem that is visible in this picture is less than a quarter of the whole stem. The plant was in a 3.5" pot - which in no way could support this stem and blooms - so I had to put it inside a 6" clay pot to keep it from tipping over. It got S/H'ed with the rest when I left for vacation, so I'm really hoping it makes it through.

    Phillip and I are both doing well now, visiting with my 17 year-old son, Henry, and sitting by the pool. Home by Tuesday - and hopefully some orchid nurseries in between!

    P.S. I took this photo with my new cellphone (vendor name not disclosed!)

    Allow me to add to your confusion Maura ; triploidy is nothing to do with 3 flowers, any more than diploidy is to do with 2 flowers - it just means 3 sets of chromosomes instead of the2 sets which most plants ( and people too ! ) have. I won't go further down this road as to why... but many triploids seem to be sterile, and if they are not, my opinion is that some of the pollen cells or seed cells have reverted to the diploid condition.
    But 3 is not bad for this species ; most of the true "multiflora" paphs are seen in photographs with 4 or even 5 flowers, but this demands a bigm, strong, almost certainly multi=-growth plant in absolutely peak condition. Anything less - like a younger plant , one flowering with only one mature growth and few if any older growths still active to spport it, will certainly have less. Paph rothschildiana "Commander" FCC/RHS was regularly shown in UK with 5 flowers - on a plant filling a 10 inch pot, and with two other flowering growths at the same time, but I know someone - a great cultivator - who is siad to have paid thousands for a division, and never managed more than 4 flowers in the first 5 or so years he had it...

    Allow me to thank you for adding so kindly to my confusion, sir! I went back and read my post with the lowii photo to see how confused I sounded and I can see where I may have gone wrong. I actually am quite aware that triploidy is having 3 sets of chromosomes, and that, in general, plants, as well as people(!) have 2. The idea of triploidy applying to the 3 flowers never occurred to me, but has amused me immensely this morning as I contemplate our plans to to take in the Orchid Show at the Marie Selby Gardens in Sarasota, Florida - 2 hours north of where I now sit. My understanding is that somehow triploidy, in producing both larger "better" flowers, sacrifices the number of blooms and, in most cases, the ability of the plant to reproduce, whereas quadriploidy (I assume that "4N" refers to that, but I may well be wrong), on the other hand, results in a plant with stronger, better blooms (perhaps more of them - I forget), AND makes the plant a good candidate for a "stud" plant, as it is also fertile. What I really don't understand is the biogenetical aspects of going from 2, 3 and then to 4 sets of chromosomes. How would one do that when paphs are reproduced with pollen and seeds? How would that affect the genetic structure? And are triploids truly the infertile "beauty queen contestants" of the orchid world? Wouldn't that be like athletes on steroids? An unfair advantage????? My mind goes round in circles like this sometimes - a little knowledge is more confusing than dangerous in my case.

    In any case, my mind has been put to rest about the number of blooms on my lowii - indeed, if it ever blooms again with such robust elegance, I shall trot it down to AOS judging to see what they have to say about it. In the meantime, I enjoy it tremendously. Do you grow any lowiis? Are there any common lowii hybrids - with other species in this genus, I mean?

    [QUOTES from =mauraec;293981]

    "Do you grow any lowiis?" - just a couple.
    "Are there any common lowii hybrids - with other species in this genus, I mean?[" most famous ones (?) Julius ( x rothschildianum) ; Berenice ( x phillipinensis) Toni Semple ( x haynaldianum ) Robinianum ( x parishii ) , , Mercatelliaa ( x stonei) , Song of Love ( x liemanianum ) - I have all of these - and there are maybe 50 others registered. Also some 2nd generation crosses are well-known, e.g. Saint Low ( lowii x Saint Swithin ).

    I'll do you a short post on ploidy to follow.

    [QUOTE=mauraec;293981] What I really don't understand is the biogenetical aspects of going from 2, 3 and then to 4 sets of chromosomes. How would one do that when paphs are reproduced with pollen and seeds? .

    I/QUOTE]

    When a cell is about to divide it duplicates its contents, so you get to have four sets of chromosomes; then a new cell wall grows to divide the contents into two sets, each with the "proper" diploid set. If the wall does not grow, and it can be stopped by an appropriate chemical poison - e.g. colchicine, then you have a tetraploid ( not quadriploid) cell which will usually go on to cell division by again doubling its contents, so that each new cell also ends up with four sets, as a tetraploid. Such plants are not twice as big , do not have twice as many flowers etc etc. but what you do get is a plant with thicker leaves, thicker petals ("more substance" - which usually means longer lasting flowers ) stronger colours - maybe doubling of the number of anthocyanine or whatever pigments in the cells you see . But , the downside is that they are slower growing - they have that much more work to do - which is why ( perhaps) the better forms of Paph rothschildianum and the big multifloral paphs - for example - commonly take 10 years from deflasking to flower the first time, and don't make a new flowering growth each year, and takes two, three, four years to mature the new one- hence longer intervals between flowering.
    The proverb which covers this is " There ain't no free lunch".
    When the tetraploid is crossed with the diploid, you get triploids ( you can work this out now I trust..) Here you get the benefit of the improved substance etc without the penalty of the slower growth. Usually infertile - that's the no free lunch with them..
    But there are exceptions to all these things - and I can only speculate why some triploids breed freely - maybe the triploidy does not apply to their pollen , maybe there is a way round cell division when there are three or five or seven or whatever sets of chromosomes...

    Hope this helps.

    Will post a set of pics from our show when I get a little time , but the house is full of a second set of family, taking me to another birthday celebration meal..( and secretly I am desperate to get into the greenhouse to get on with my repotting... but I daren't say that out loud ! )
