    This little gem has decided to put out 9 stalks this year, most of them are so closely spaced you cannot distinguish them. I took a series of pictures because I love the buds as much as the open flowers, they look like little aliens to me.

    That is incredible. Can you share some of your culture conditions? I recently replaced mine, and seem to have trouble with getting keikis instead of spikes

    Heike, that is stunning. Congratulations.

    Mine just sits there doing nothing. I recently moved it to brighter light so maybe that will help it. How bright do you grow yours?

    Gorgeous and tremendously well-grown! I killed one a few years back and haven't attempted it again yet.

    Thanks for the kind comments!

    Calvin and Kelly, I don't feel that I'm doing anything special, here's what I wrote last year:

    Recently I've gone down with the fertilizer to about 100 µS (because of more sensitive plants in the same aquarium). I think perhaps the rather dry cultivation is most likely to be different from the standard. Also, the lamp has been a 5000 K for some time now.

    Great culture! By any chance do you know is that one of the 4n forms that has been available?

    Thanks! Marni, I don't think so, the flowers aren't bigger than usual and I didn't get it with any name addition. I'm not sure there were 4n plants available here in Europe.

    I got quite a few plants of a 4N Aerangis luteoalba v rhodosticta from Popov many years ago. I later did a sibling cross of them (also years ago) and the seedlings in flask were very difficult. But none of my plants ever bloomed as well as yours.

    I see, this I didn't know. I bought mine as a seedling maybe 4 or 5 years ago. Do the 4n plants have bigger flowers?

    My very favorite Aerangis species, perhaps for the entire Angraecoid family. Nicely done!:clap:

    Aerangis luteo-alba f. rhodosticta DSC_1375.jpg Aerangis luteo-alba has been a favorite of mine for over 30 years when it was known by the more appropriate name of rhodosticta. Luteo-alba was based on a herbarium specimen that didn't show the red. To the best of my knowledge, no specimen of the yellow-tipped variety has ever been grown. I helped introduce it back in the 1980s when my professor brought back seed from Kenya. I find it trivially easy IF you give it what it wants. In nature, rhodosticta grows on vertical tree trunks in gullies in places like Masai Mara, Kenya. Still fairly dry compared to a lot of genera we grow. I mount them on cork with just a pad of sphagnum to start out. The very thick roots will attach to the cork quickly and they will tolerate rather dry conditions in semi-shade. I find this method worked essentially 100% including just out of flask. No coddling! I have had them bloom in flask. Most will bloom in 2 – 3 years from seed. Cattleya temperatures but very tolerant at both ends.

    I didn't know that Popow had sold 4n plants! It might explain what I'm experiencing now...some years ago I too purchased plants from Popow, and some others from an unrelated source. Popow's plants flowers were quite "rounder" if not bigger. And I crossed Popow's plants (4n?) with the other source (probably 2n). Now I only have plants from this crossed batch. And haven't been able to set any pod since on that species! I guess my plants are sterile triploïds...

    Absolutely beautiful in presentation and the culture behind it. Congratulations for your great success. Would be intersted in the fertilizer schedule used to produce such a prolific plant. I have two smaller ones. One blooms constantly and the other arrived blooming but it was stressed from the trip. Nevertheless, they are iconic examples; and, yours is in the contest for the top! /drc

    Pixietoe (Heiki) is a wonderful grower. She might not see this for awhile, so don't feel ignored if she doesn't get back to you soon.
