so beautiful in bloom but... what cactus is it?

[sickboy83]

after days of waiting, it bloomed today. but I don't know her name

Looks like Echinopsis subdenudata

[Arjen]

sure looks quite a bit like it, but isn't e. subdenudata supposed to be a nightbloomer?
and all the ones I have seen before were globose, etoliation here?

[Loph]

looks stretched to me too. mine are also only night bloomers, but i think that rule could be easily broken in certain situations.

I think they are night bloomers, but mine stays open for a while in the morning. If they are primed to close as the day gets brighter, and that one is in a low light situation, it may be able to stay open longer in the morning.

Whatever, when the flower is open in the daylight you can enjoy it more!

Curious - in line with my question on pot shape influencing plant shape.

How much has the smallish pot influenced the shape of this plant as opposed to low light? Which is more responsible or am I way off here?

[Hardy_whv]

There are so many hybrids of the E. eyriesii, E. oxygona and E. subdenudata group that I personally thinks it's impossible to state, that such a plant is a certain species, unless you have it from reliable sources with the name tag still on it.

Some Echinopsis of this family (i.e. eyriesii) grow higher when getting old. So it does not automatically have to be a deficit of sunlight.

Concerning pot size: Abnormal height-growth is not caused by pot size. It's always a lack of sunlight IMHO.

Looks like Echinopsis subdenudata

that would be my guess too, or a hybrid with a lot of subdenudata in it.....
