Hippeastrum 2011

[Cris]

This is the first Hipp of this year....I don't know it's name. I thought in Vittatum, but I've doubts...

[Ezeiza]

Seems to be the real vittatum, a very rare species in cultivation.

Lovely Hippeastrum Cris. 

Well, I grew H. vittatum from seed more than 15 years ago with not a single flower to this day - am I dumb or what? 

[orpheos]

i've bought this one as vittatum... isn't it?

[jshields]

Probably not vittatum; almost certainly a hybrid.  My own vittatum has so far never bloomed.

I agree with Jim, this is a hybrid. 

Jim, I think they require a lot of sun to bloom properly or at least that is what I've been told, where are your H. vittatum from?

I got this one from Kelly Irvin in 2004, Josh.  I have some much younger vittatum bulbs from seed from Mauro Peixoto in a different greenhouse, and all of them are in partial shade.  Maybe I should move some out into full sun and see what happens (will they bloom or get virus infections first?)

I got rid of all the vittatum I had many years ago, since I suspected all were hybrids of various sorts.

Jim, sadly that's the problem with leaving plants outside  I have a few from Mauro as well and they seem to be doing quite well.  Do you know where Kelly got his H. vittatum?  His plants are much different than anything I've seen, they're very interesting!

Josh:

Kelly is a he!

Thanks Arnold hehe!

Did your Rauhia wake up this year?  Mine are starting!

Jim, vittatum has a white ground with red stripes. It is Peruvian, not Brazilian and very uncommon in cultivation although someone recently showed on in flower at this same forum.

If you sprinkle with  systemic insecticide granules, there is no reason why you will have sucking insects. A useful tips from commercial narcisus hybridizers is to grow plants that are very attractive to aphids like cereals, (barley is the plant commonly used) and treat these with systemic insecticides on a regular basis. This way aphids never reach your valuable plants. And if you fertilize these, they become irresistible to them.

Alberto,

    I'm a bit confused, the plants found in Brazil are actually other Hippeastrum than H. vittatum?  This is one of the problems with the genus, many plants are considered a synonym for H. vittatum and are named wrongly!  H. canterai, H. guarapuavicum and H. harrisonii are all said to be synonyms but it's hard to know what is true unless some DNA work is done for proof..

   According to Kew tho H. vittatum is found from S. Brazil to Argentina (Misiones).

[Rogan]

My H. vittatum plants I grew from Chiltern Seeds' seeds, so they may very well turn out to be hybrids - but they won't flower!  

P.S. I just picked this up in another thread where Ray was saying, about Peruvian Daffodil (Clidanthus): "It seems to me that to get these to flower they must have a good source of potassium, dry winters, no frosts and hot summers."

It's worth a try!

[Rogan]

H. calyptratum, open for business - extremely odd, but quite enthralling!

[santo2010]

I agree, Odd but enthralling! Beautiful!
