Title: Hippeastrum 2019
Post by: luca on February 28, 2019, 08:21:15 PM
My Hippeastrum  teyucuarense

 H. teyucuarense is reported in the department of San Ignacio (province of Misiones, Argentina), where grows in a single hill called "Rock of Victoria" (Teyú-Cuaré Provincial Park, Province of Misiones, Argentina) among rocks and rich soils.

Rare in cultivation.

Maybe synonym of   H. glaucescens and H. iguazuanam

Jörg,

Makes me think of H Aulicum.

Hello,
nice Hippeastrum species shown!

I like to share a small story. All started some 20+ years ago with 1 bulb present for christmas bought from a discounter...
It flowered, grew and clumped up, see image 1 from 2012.

Finally was repotted in a 60 cm diameter container, grown outside in summer, stored in my garage over winter during dormacy.
In 2013 I counted ~25+ bulbs. Image 2
The flower stems can grow 90-100cm high and each flower can reach 20 cm in diameter if you fertilize...Image 3

Now in 2019 the clump became to congested. Time to repot... Image 4

Image 1 of the post shows the flower last summer (June). Around 20 flower stems were emerging, however the flower size was smaller then usual...

In Image 2 you see a pot full of roots. Incredible. It was impossible to separate the bulbs without any losses of roots...

In total 52 bulbs in all sizes were separated. Image 3. :D

I repotted the 5 largets bulbs in my container. I used a dry sand compost mix with organic fertilizer.
The other bulbs got single potted and donated for a school party with tombola.

My bulbs remain stored dry in my garage until the bulbs start growing. When new flower stems reach finger lenght I start watering.
I put the pot outside when it is frost free and I grow them until mid of November dependent on first frosts. I stop watering by end of September.

The hybrid name is 'Naranya'. A dutch grower told me when I showed him my images.
End of story... :)

Quite a story, Armin - and a very successful one at that!  I can  see in image SRGC-20190306_141314_002.jpg that the  many bulbs are  distorting  even that big strong pot!

Large bulbs & tubers have already made several of my pots simply burst.  Smaller ones just get compacted and start to grow in layers.

Maggi & Francois,

indeed, the pot was quite distorted and close to burst. :)

Hippeastrum brasilianum is blooming this week. Although this species is said to be self-fertile, my plants have never shown that trait. As its name suggests, it is native to Brazil, in Espirito Santo state. These plants were grown from seed from Mauro Peixoto planted 12 July 2005.  Since two separate clones are blooming at once, I have tried cross pollinating them.

This species is Hippeastrum yungacense, which is native to Bolivia.  It was described by Cardenas and Nelson in 1965 in Plant Life 21: 57 (1965).  Hippeastrum escobaruriae is considered to be a synonym for this species.  This plant came from Yann in 2014, and it bloom for the second time this year on March 22.

Hippeastrum iguazuanum in bloom.

Species within subgenus Omphalissa. It is native to the province of Misiones (Argentina) and the Department of Parana (Brazil).

Luca,  I'm glad to see other examples of Hippeastrum iguazuanum.  This plant grew from seeds that Mariano Saviello gave me in 2014.  Mariano said that his plants were self-fertile, but I have not so far been able to set self seeds on my plant.  Have you gotten seeds from your iguazuanum yet?  I have another scape coming on this plant, so I will try again for seeds.

These are Hippeastrum puniceum, from Brazil. The seeds came from Mauro Peixoto and were planted in November, 2007. They have been blooming each spring for several years now. This batch is number 2264, a mixture of seed lots from several localities in Brazil.  They set seed very easily.  I am used to seeing puniceum as a bright red flower, but these from Brazil all have this interesting pastel color.

This is Hippeastrum evansiae, another native to Bolivia.  It is somewhat variable, especially if you include H. anzaldoi as a synonym of evansiae.  For many years, no one could seem to get seeds from evansiae.  It is self-sterile, and there was apparently only one single clone of it in cultivation.  Recently, several other clones have appeared, and we are now able to produce seeds of this nice little species.

My #2053 (above and next one below)

This one was collected by the late Bill Janetos in Bolivia.

This one is not white to the human eye, only to the iPhone camera.  It looks to be a nice light lemon yellow to my eyes.  It came to me from Telos Rare Bulbs by way of William Hoffmann.  My #3010.

Have produced seeds your Hippeastrums?
Title: Re: Hippeastrum 2019
Post by: jshields on June 16, 2019, 12:42:54 PM
Luca, et al.,

I have produced some seeds, and have sent some out, mainly to folks who have sent me seeds in the past.  Overseas postage has gone up considerably in the last few years, so I do not ship seeds out willy nilly anymore.  I suppose I should send my leeft over seeds to one of the seed distributions.  Hippeastrum seeds do not keep well after the first few months.  So i have not gotten around to sending any to the SeedExs for the last couple of years.

But It's a pity lost rare seeds.

In the picture H. harrisonii seedlings. Raised from your donation to PBS   ;-) . 2 years ago

This seedling bulb of Hippeastrum yungacense recently bloomed for the first time for me.

This grew from seeds sent to me by Ann Shubin in Australia.  Its sibling bloomed in March.

This cute mini Hippeastrum is from Taipas in Brazil. It still lacks a scientific name, but Mauro Peixoto and his collaborators are working on giving it one.  So far. most who grow it are calling it simply Hippeastrum "Taipas."  I think its proper designation at this point is Hippeastrum sp. nov. ex Taipas.  Mauro offered seeds of this species two or three times.  I got the seeds for this plant in 2008.  I had a bounteous bloom of Taipas seedlings a few years back and distributed seeds from that year, but have not gotten seeds from them since.  I will try again this year, as another plant of Taipas has a scape starting to grow.  I am storing some of its pollen just in case.  Mauro has not offered seeds of Taipas for several years now.

[attach=1]

The peduncle is about 42 cm high on this greenhouse-grown specimen, the pedicel is 30 to 35 mm long, and the diameter across the face of flowers, petal tips to petal tips, is 70 mm (2.8 inches).  Regis Bastian, in Brazil, thinks this species is probably related to the new Hippeastrum species, H. ramboi, whose naming he participated in.  These are exciting time in genus Hippeastrum!

Very cute this small hippeastrum...

How long do flowers last?

Hippeastrum "Taipas" blooms every year?

I think Taipas should bloom almost every year if you have enough plants of it growing.  I am not so sure that every bulb will bloom every year.  "Taipas" flowers last for several days if you don't mess with pollinating them.  They are part of a complex of late Fall and Winter-blooming species in Brazil in the process of being named now.   Two of these new ones are Hippeastrum multiflorum and H. ramboi.  Taipas did well in my greenhouse, but it remains to be seen if these other two will also thrive there.  It is said that H. multiflorum is like a weed, so I ought to be able to grow it.

Hippeastrum calyptratum is blooming just now in my greenhouse, and I want to post these pictures before I forget it.  Calyptratum is native to Brazil, where it grows in an epiphytic manner.  They don't usually survive let alone bloom in my greenhouse, but  this one batch of seeds from Mauro Peixoto has produced three surviving bulbs, two of which are blooming or ready to bloom.

[attach=1]      [attach=2]

 I have stored some fresh pollen from this one and will try to produce a few seeds when the second bulb blooms shortly.  Note that the pollen was not yet ready when the pictures were taken.    I normally donate my extra seeds to the Pacific Bulb Society's BX/SX  --  https://www.pacificbulbsociety.org/ (https://www.pacificbulbsociety.org/)

The Hippeastrum aulicum plants are starting to bloom in the greenhouse. It seems too early to me for this, but here they come! Hippeastrum aulicum is native to Brazil, where it has sometimes been found swinging from a vine on a tree. This is the form from Corupa, from seeds supplied by Mauro Peixoto.

I expect to get a lot of seeds from the various accessions of aulicum that I have.  They should bloom off and on until about January.

Although I'm in Europe, my Aulicums have also been growing much too early.  In fact, they already started to push some new leaves by end of June - where normally I give them a dry summer rest during July & August - still in full leaf from the previous growing season.  Anyway, I did not water them this summer, their growth was suspended, I resumed watering last week and immediately they responded with fast growth.  I expect they will flower in about one month - as they did last year, and which is about 1 month earlier than in previous years.

Here is another of my Hippeastrum aulicum accessions starting to bloom.  This is my #2144, which also came from Mauro Peixoto.  Unfortunately I neglected to record the location data that accompanied these seeds.


[attach=1]         [attach=2]



These petals look rather opulent for ordinary aulicum, at least to me.
