single variegated hippeastrum seedling

18 years ago

In the past year I have repeatedly published the valuable advice to perform sowing of hippeastrums on the highest scale one can afford.

On a production bench of 3 m2 I can sow out a maximum of 3000 seeds in 12 boxes of 50 cm x 18 cm.

Thus I could always easily follow my recommendation and have sown all seeds derived from all my exotic crossbredings, among them 120 seeds of

H.aulicum v.robustum x H."Giraffe"

The sense of mass sowing is to explore the degree of uniformity and the relevant differences in shape and growing characteristics and... to discover some accidental specialities - I like to say ornamental anomalities, with a higher detection probability.

I have now made a simple but f_cking good observation of a particular kind of variegation.

The white ligament is developed on the leaves of one side only (I considered even that just nobody will believe me)-

and it has nothing to do with a discoloration which is restricted on the midrib of those "affected" leaves of the respective one line.

This latter has successively come to light in the younger leaves, as the ligament tends to broaden, to slip towards the left half area of the leaf surface and tend to split, too (three thin green streaks can meanwhile be seen embedded in this broader ligament)

This developmental dynamics are so exciting, and my anticipation is fortified because I must wait for every 2nd next leaf to determine what kind of progress *g* the variegation has undergone.

Interseting Hans, Please update it's Progress as I'm Interested in seeing if it Continues 1 into the next Generation and what affect it has on the Flowers
Thank you for Sharing this with us...

Hans-Werner, that is fascinating and very lovely.

I'm curious: do you know what might cause variegation on only one "side" (for lack of a better word) of the leaves? I've heard of this sort of thing with Iris germanica blooms, but have never received a satisfactory explanation as to its cause.

At any rate, what a great discovery. If that were my plant, I would be feeding it like never before, trying to push new growth to see what happened to the variegation. :) There sorts of things really try a gardener's patience...but are worth the wait, I think.

What is the probable ploidy of this seedling? I'm curious about what you might cross it with. Do you have H. 'Santos'? This one has beautifully variegated leaves, although they are not as striking as the leaves on your seedling--the variegation on Santos is dark green/light green. But what might crossing your seedling with a variegated hybrid do for the offspring? (I believe Santos is diploid. At least I hope it's diploid, and not triploid. I attempted to cross it with various 4ploid hybrids last year, and got nothing. So this year, if it gets over sulking after repotting, I will try it with 'Emerald' and the like.)

Sorry for so many questions; it's just such an interesting phenomenon. Thank you for posting on it.

No problem, Bergit; My amaryllis did not suffer at all, as I expected. They only suffer if they are exposed to cold and WET. That is the important difference! Provided the uppermost part of the bulb and the green parts of the plants and particularly the HEART remain completely dry no fungal diseases get access to the plant - although its resistance forces are lower when kept cold for a prolonged time. Unfortunately (but as expected, too,) these both beautifull scarlet red 3ploid H.aulicum x "Liberty" failed in producing seeds... The last Hippeastrums to come into bloom will be the highlight of the season. These are as I already indicated elsewhere 4 seedlings of H.papilio + ("Ambiance" x "Donau"). OhOh...Big curiousity and excitement meanwhile! Hans-Werner

Amaryllis ( Hippeastrum ) and how I came to love them.

So this is my story! When my dad bought our house in La, CA about 25 years ago it came with several Amaryllis bulbs planted along the driveway. I dont know what kind but i will definitely put a pic once they bloom again. But they are like red trumpets on a green stalk. One day maybe when i was like 10 my parents decided to put cement over the strip of dirt where the bulbs were planted. My uncle was gonna throw the bulbs out but my neighbor saw him and asked if she could have them and he said sure. Our house was built in 1944 but i have no clue as to how long the bulbs were there. About three years ago i went over to my neighbors house and she said i could have a pot of the amaryllis bulbs. She had many by now with all the offsets that grew. I planted them all in a sunny area in my backyard along with another amaryllis plant that grew up out of nowhere. I woke up one morning, went to my back yard and saw a bright pink flower between some wood and the cement. very unusual place for a flower. I dug it up and it was very deep in the soil. it didnt have any leaves just the stalk and flowers. and the next year nothing grew up. the year after that it was the first amaryllis to bloom again with no leaves. and this year it only grew leaves but no flower :(. im guessing it was planted toooo deep. It had an offset but i think i put it in my garden somewhere idk. This amaryllis?, not sure if it is but surely looks like it, is the most beautiful amaryllis that ive seen. its bright pink and had about 6 or 7 flowers on its single purple/brown stalk. I planted it in a differnt area and it did not take well. just yesterday I put it in a pot with good soil and put it in a sunny area. Hopefully it grows back so i can get it identified as well and also pollenate it!!!! I think it has a good chance of surviving. I actually cut a little off the top of the bulb like a couple centimeters or two just so its neater but idk hopefully i didnt kill it. And about a couple months ago I pollenated all my flowers and I got the 12 + pods of seeds from my neighbor and planted them. I had to throw some into the garden because there were so many. I actually check my planted seeds every other day and they are taking root so yay!! I will have a lot! So if annnyone ever wants to trade for other amaryllis bulbs let me know! idk if i can ship bulbs in the mail? Can i? Would i ship it in a little baggie of soil? idk Well thats how i came to love Amaryllis and im only 18 so lets see how long my passion lasts. Im guessing forever! If you have any advice or suggestions please let me knowww :D

Soultan - I'm very happy to hear you're having the meeting taped!! Great idea! Perhaps it will help change things a bit in your favor! I am more than interested to hear how things go at that meeting! What a shame the orchid-lady's greenhouses are in disrepair... any time I see an empty greenhouse, I always think what a waste it is, going unused like that... and it's also a shame that you have no sunny window space to place your seed trays in... that all being the case, I hope you have your seeds stored well! Perhaps when everything is said and done, and the construction is over, you can finally find the space and time to get them planted. Primeribs - There was a time, not that long ago, that I would have said your name is making me hungry... I love prime rib! Nice thick, juicy, medium-rare to rare prime rib swimming in its own juices! Mmmmm! But I haven't eaten meat in a long time! I'm not a vegetarian... I went healthy and decided to lose weight and boost my body with good nutrition. I have Lupus, so my immune system needs a lot of help! I eat 2 meal replacement shakes a day, fruit and yogurt, and a handful of vitamins. I've lost almost 40 lbs., I hardly ever get sick, and I feel pretty darn close to "great"!! As far as seed viability goes, I think genetics has a lot to do with how long they last. Storage method would also be a factor, as Elizabeth noted. As with any seed, though, the longer you wait to plant them, the lower the germination rate... I keep all my seeds in little paper envelopes in a closed container, and for some reason, I never seem to be able to throw out old annual and perennial seeds that I've saved. It's the "packrat gene" in me! Last spring, I planted several packets of perennial seeds that were at least 4 years old, maybe older... the germination rate was very low, almost non-existent! I did manage to grow a few plants from each packet, but I sure wish I had planted them sooner! I did notice, however, that even some of the fresh seed I bought this year had a low germination rate... I wonder why that is? Even the green beans I planted had a low rate, and those seeds grow like weeds normally!!

Nice to "meet" you, Orchid Boy! I'm just beginning to collect orchids... and to learn about their many different requirements. I found out a bit too late, I think, that clay pots and Phals do not mix in the chilly northern winters, even indoors! I plan on trying a few other orchid types this spring, to get a feel for what my environment can support... Dendrobiums, Cimbidiums and Epidendrums are the three I'm thinking of, since I already have an Epi that's doing well... or maybe a Catt... I do like your crosses, and where you're going with your breeding program! I got one giant pod from my Exotic Star... it was a self. The more I look at the red/greenish bloom you posted, the more I like it... the coloration of the pollen bearing parts is very unique! (I keep forgetting the terms for the individual parts!)

Hello Amanda:

Do not worry about your many questions - instead I thank YOU for your interest.

So at first I like to confirm that the plant is cared the very best way for, sitting in an "own" 13cm (2l) TEKU-Tainer under Osram L-Fluora tubes (200 W / m2; 16 h/day ) and guess, I even know rather accurately its actual water consumption at 22-24Â°C that is 45 mL / day.

As regards to inheriting this fine ornamental property to generative progeny I am not at all optimistic.
I assume that this feature is somewhat more "superficial" - not at all embedded into the generative cell line initials (sorry for unadeqate terminology) I would just feel big satisfaction if I could finallly "bring" this variegation on the leaves of both lines.

My speculation is that bulblets from the variegated side will emerge variegated leaves only. That alone is good motivation to do the very best for the plant. Fortunately and as can be seen from the line of seedlings laying on the floor this exceptional seedling is one of the best growing of the grex from this H.aulicum x "Giraffe" cross.
And furthermore both parents are well known offset producers

The ploidity of this seedlings should be 2n; this is common for species and rather the primordial hybrids.

2n cultivars cross with other 2n cultivars (selfing being mostly impossible).
2n cultivars can SOMETIMES accept pollen of 4ploid hybrids.
One which accepts promiscuitely all pollen regardless to coming from 2n or 4n cultivars - that is the above mentioned mother plant H.aulicum v.robustum.
To the reciprocal attempt, I NEVER experienced any 4n cultivar to accept pollen from 2n, while these often big blooming hybrids are easily crossed among one another and selfed, too.

If you believe this beautifull straight white ligamented gracile H."Santos" with its dark variegated leaves to be 2n - what would you presume in the case of the similar "Baby Star" ?! - (It is a 4n from the gracilis subgroup)
But please do not give up trying "impossible" crossings. It is only a question of time and of the number (of attempts)

{{gwi:3636}}href> {{gwi:3638}}href> {{gwi:3640}}href>

Incredibly but true: The bulb has meanwhile formed a first offset.
But - alas - the first two leaves of this bulblet are... green - oh no - solely green

Hi Hans-Werner, It continues to be impressive!!! Were the offsets produced on the side of the mother bulb that is producing all green leaves?? It looks like from the pic that one side of the bulb is all green leaves whereas the other side has the variegated leaves. Once you get an offset from the variegated side then you will know whether it can be vegetatively propagated or if you will have to stabilize it with a cross I would think. As you may know the only variegated Amorphophallus konjac in existence started with just a smidge of white on the leaf from one side of the tuber. Daughter tubers from that side of the plant ended up being variegated, but those from the all green side were not so I think this is probably pretty typical for bulbous plants, although perhaps this is not the case...a variegated plant nut could help on this!! Please keep updating us :o) Dan

Yes I find this variation of the striped character very impressive, too.
Now please have a closer look on the enlarged version of the center image. You can see the little green pin, below, on the left side?!
This skew orientation is exactly that from the variegation itself, not that from the whole leaf bunch of the left side/line.
I have to wait for a further offset in the latter orientation. Or perhaps for several - and this is simply thrilling.

But I am thankfull that this young plant exhibits offset formation in this early stage (1 y old) and I am confident that I shall have definite info - provided by further bulblets -within 2006.
