Hippeastrum 2016

[johnralphcarpenter]

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


Hippeastrum glaucescens




More scapes coming.

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.



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.



Another Hippeastrum glaucescens blooming today, sibling to those that bloomed a week or so ago:


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.
