Hippeastrum mandonii is starting to bloom in the big greenhouse. This is pretty late for mandonii. Last year, it didn't bloom at all, and the year before that it refused to set seed when self-pollinated.

Right at Christmas time in December, 2015, many of my Hippeastrum aulicum bulbs bloomed.
[attach=1]
I pollinated these flowers among themselves like mad. Now, about 1 month later, it looks as if only very few actually are maybe going to make seeds.

You'd wonder just what these plants do want, wouldn't you? Very rewarding when thing do go right , though!
-
I also pollinated my flowers in 2014. Allthough I started with 2 bulbs they must be the same clone and so not self-fertile (like many Hippeastrum species), in the end small seedpods did develop, but there were no seeds in. Perhaps we should have a pollen exchange here to overcome nature's barriers to inbreeding. But still check for provenance (my bulbs also come from the USA).
-
A pollen exchange would be a good idea, especially for anything in the Amaryllidaceae. I have my approach to storing pollen described at:
http://www.shieldsgardens.com/info/Pollen.html (http://www.shieldsgardens.com/info/Pollen.html)
In my experience, Hippeastrum pollen is only good for a little less than 12 months, so none of the pollen I currently have stored in the freezer will be viable anymore. The stuff on hand is at least a year old, or older.
I have H. psittacinum (ex seed from Mauro) about ready to bloom, if anyone is interested in that pollen.

Sadly we in Australia cannot receive pollen from overseas now because of the threat of varroa mite to our honey-bee population :(

Jim,
The seed of the various Hippaestrum species germinated extremely well and are coming along (i.e. getting big). It will most likely be anther season until they start blooming. I will be glad to share pollen with those that are interested when they start blooming.
-
This is Hippeastrum psittacinum, raised from seed from Mauro Peixoto. This species is native to Brazil, and I think it is probably closely related to H. glaucescens and H. iguazuanum. This bulb is blooming for the first time, and with two scapes! I think other seedlings from this batch probably bloomed last year.

I am trying to self-pollinate this one, since no other bulbs of psittacinum are showing any signs of a scape so far.

Sorry about the cockeyed images. I had them rightside up to begin with, but they were in OneDrive, Microsoft's cloud system. So I will blame Microsoft for screwing up my pictures!

I've straightened them up, Jim! :)

Thank you, Maggi! The world may be getting a bit too complicated for me.

I doubt that, Jim! I The sideways "thing" seems to happen at random - but quite often. I think it's something to do with how the initial files were saved - but I don't know really! :D

Hippeastum vittatum flowering now.

Hippeastum vittatum flowering now.
I am not at all sure what vittatum is supposed to look like. It is probably extremely variable, since H. harrisonii is also supposed to be a synonym of vittatum.

Hippeastrum harrisonii
On another note, my self-pollination of H. mandonii seems to have failed. Selfing psittacinum results are still up in the air.

Mine is similar to the one pictured on the PBS Wiki, but with less pronounced white markings.
-
The bulb which I bought from Himalayan Gardens as Hippeastrum (Rhodophiala) rosea is flowering again. They have sent me a replacement so we will see if that turns out to be the true species.
-
Not what you expecting but not too bad a flower :-\
How big is the flower?
cheers

Eight cms. long and wide. Probably a hybrid. Could be H. `Gracilis`.
-
Hippeastrum blossfeldiae flowering in the polytunnel today. Huge.
-
Hippeastrum bukasovii, probably a hybrid, seed from Doug Westfall. Other parent unknown. A lot of its siblings are also in bud right now in the greenhouse.

Below, Hippeastrum psittacinum hybrid. Other parent unknown.

and finally an old hybrid of mine blooming again:

Hippeastrum [papilio x mandonii]

More Hippeastrum blooming in the greenhouse:
Typical Hippeastrum morelianum
[attach=1]
Hippeastrum glaucescens
[attach=2]
[attach=3]
More scapes coming.
Jim
-
According to Mauro Peixoto, from whom I got all these seeds, this is the "Atibaia" geographic form of the very variable Hippeastrum morelianum. Since this looks alot like psittacinum when side-by-side, this could be a morelianum-psittacinum natural hybrid.
[attach=1]
I have resisted the temptation to cross these two forms of morelianum, but I did try to self the plant of the more typical form. This Atibaia plant I will leave virgin, at least for this season.

Jim, what minumum temperatures can these plants take?
I grow a number of South African Amaryllids (Boophone, Brunsvigia, Cyrtanthus, Haemanthus, Gethyllis) in a sand plunge (minimum plunge temp +7’C, minimum air temp +4’C) in a greenhouse.
Would these minima be suitable for Hippeastrum sp.?

Sorry, Steve. Unlike the South African species, these South American plants need to be kept well above 0°C. My South African house hits +/- 1°C every winter on cold nights with no problems. I keep the house with the Hippeastrum plants at close to 10°C. HH. morelianum, psittacinum, aulicum, reticulatum, striatum, and others that slipped my mind, are from Brazil and mainly forest understory habitats.
When you try it, maybe you should try an Andean species, perhaps Clinanthus.

Many thanks Jim.
You have prevented a crime (Hippeastricide)! ::)

Hippeastrum cybister is blooming. From IBS seeds many years ago, one clone (#960.G) now blooms almost every year. Until now, no other seedling from those seeds has bloomed, but now there is bloom on another (#960.B) which I am using to pollinate G. I hope I finally get some seeds of cybister to share.
[attach=1]
Another Hippeastrum glaucescens blooming today, sibling to those that bloomed a week or so ago:
[attach=2]
And there are scapes shooting up on young seedlings bulbs (as little as 2 years old) of Hippeastrum yungacense and H. iguazuanum. I had iguazuanum ca 30 years ago but lost it in a greenhouse freeze. I don't think I ever had yungacense in my greenhouse before!
Finally, another Hippeastrum [papilio X mandonii] is blooming today, #1455.A:

Hippeastrum 'Black Pearl'
It is darker in real life.

Wow! Great plant!

Midsummer hippeastrum flowering - although this one also flowered already earlier in spring. I assume it's hybrid, unnamed because the label got lost. But I like those smaller flowers more than the huge Dutch hybrids.
-
I'm going to repot my Hippeastrum Aulicum at the end of this month, just before getting them back to growth after their summer dormancy, and have a 5 offsets available. Some are already close to flowering size - perhaps one more growing season needed - others will take you probably 3 years of patience before displaying flowers. Pm me with your contact details & shipping address if you want one of the offsets - the original bulbs come from the USA. I don't need anything in return, but feel free to make a donation to the SRGC if you want to compensate in any way the shipping costs. I will send the bulbs early September.
The picture below shows the flowers last winter - these should brighten up your home for Christmas.
Happy growing :)

Hippeastrum aulicum
Today the flowering season starts, two more buds are coming. The bulbs come from a gardener in Germany who told us that it stood in a corner of the greenhouse since the times of his grandmother. He even didn't know what it was. It seems to be a 'robustus' type because it makes lots of baby bulbs.
