Echinopsis species 'Dominos'

Postby Justin » Fri Jul 05, 2013 3:00 am

I bought the plant under this name. I did not find much information on internet about it.
I suppose to be a cultivar or a hybrid of Echinopsis. I'm not sure if the name 'Domino' it is a cultivar name or just a commercial name. Anyway it's a beautiful plant.
Most likely the name "Domino" comes from her areoles look. Especially when many plants are together. The show of areoles remember of pieces of Domino game.

At around 2 am, the bud began to open. On each photo, on the comment is noted the time.

When the sun rose, the flower began to close. At around 10 am it was closed forever. And this is the whole story of this flower.

are you sure this is 'domino'? it looks like an E. subdenudata to me
beautiful flower though!

Altman has them labeled as Echinopsis hybrid "Domino". Guess they didn't bother to add the subdenudata. I picked one up at Home Depot - the usual too much peat & globs of glue/flowers. The good deal was, with such a smooth body, the glue came off without much damage. Had to wash the peat off the roots but seems OK so far. So cheap I figured it was worth taking a chance.

I think he may be just a cultivar / selection oe a variety of E.subdenudata.

Here, the label of original pot, how I bought this cactus.

It is Dominos no Domino. I edited the topic title, the name to be exactly as on label. Sorry for this.

On the side of the label (not shown in picture), is mentioned: Altman Plants Vista, CA.
On the web page of Altman Plants, searching for Echinopsis I found

http://www.cactusshop.com/library/products.aspx

Under common name they have "Domino Cactus". I suppose it is the same, even for the genus it is mentioned Pseudoechinopsis.
I can't find anything about genus Pseudoechinopsis. Maybe it is about thee section Pseudoechinopsis, of the genus Echinopsis
http://www.erowid.org/references/refs_view.php?ID=7114
But, I don't have an overview of the genus Echinopsis, so all these are just guesses.

Comparing
http://www.cactusshop.com/library/Image ... px?id=2830
and
http://www.cactusshop.com/library/Image ... px?id=1509

First I noticed a difference in the appearance of areole. In the first case the areole wool appear more like big dots. In the second case, E subdenudata, they appear like short horizontal stripe.
The difference of ribs can be due to the different age of plants or other causes. Or it can be and a real difference.
To be noted the difference in minimum temperature indicated.


Looking here
I noticed the areole on the first photo and on the other photos presented below on the page. That make me to suppose to be just an cultivar of E.subdenudata.

In cases like this I prefer to keep the label name, hoping the more information will be available in time.
I do not know if it is a registered cultivar or just a trade name.
I have not noticed the flower to have perfume. But maybe next flowers will have, or maybe I was not able to notice it.

That's really nice!

We've got a stick cactus in the front garden, blooms are only good for one day and already semi-wilted by the time I get out of bed. I'd need some determination (do-able) and a good bounce flash and reflective umbrella (which I don't have).

Echinopsis by our door is much more cooperative. Stays open till about mid morning, and blooms for a couple of days.

How do these guys know when to start opening? Good sense of circadian rhythm? Temperature?

Echinopsis 'dominos' and Echinopsis subdenudata are the same species, however 'dominos' is just a form with more woolly aeroles. Altman no doubt love to make up names for plants, so they seem more exotic or something. I'm fairly certain it's just a sales tactic. :P Minimum temperatures should always be taken with a pinch of salt, as a lot of plants will take lower temperatures than is documented for them. The minimum temperatures are always erring on the side of caution. :) They probably use light to know when to open their flowers.

Happy growing!

There is always one more glochid. Somewhere.

My Echinopsis sub. is blooming right now ( its almost 100 degrees here right now) for the second time this year. I love this plant even though the flowers don't last long!
